MEHTOR API — AI-FRIENDLY REFERENCE DOCUMENTATION ================================================= This document describes all Mehtor API services in a structured, unambiguous format intended for consumption by AI models / coding assistants. It replaces the original HTML documentation. BASE URL -------- https://api.mehtor.ru AUTHENTICATION --------------- Most endpoints require an API key sent in the header: X-Api-Key: The user can access this via the API Tokens tab in their MehtorAPI control panel: https://api.mehtor.ru/control/panel. Some MehtorSSO endpoints instead use: Authorization: Bearer The user can access this via the MehtorSSO tab if they have a paid plan, in their MehtorAPI control panel: https://api.mehtor.ru/control/panel. (see the SSO section below for exact requirements per endpoint) SERVICES OVERVIEW ------------------ 1. VDL — Video Download Light: download photos, videos, audio, or other content from almost any publicly accessible platform. 2. STT — Speech-To-Text: accepts a voice recording file, auto-detects language, returns transcription. 3. TTS — Text-To-Speech: accepts text + language, returns a realistic voiced WAV file. 4. MehtorSSO — Single sign-on system: lets users log into your app with their Mehtor account and grants your app access to profile data; also provides a secure key-value data store per user/app. 5. CUSTOM ENDPOINTS — If none of the existing endpoints and services meet the requirements. Free creation of an endpoint running on MehtorAPI’s infrastructure to meet the user’s needs. You can create any type of backend here: WebSockets, HTTP, TCP, UDP, everything is supported. Multiplayer and VoIP included. COMMON HTTP STATUS CODES (apply to all endpoints unless noted otherwise) -------------------------------------------------------------------------- 400 Bad Request — a required parameter is missing, or an unexpected extra parameter was sent. 401 Unauthorized — the API token was not provided. 403 Forbidden — the API token is invalid, or it is not permitted to access this endpoint. 404 Not Found — the request path is likely mistyped. 429 Rate Limit — plan quota exceeded, or insufficient account balance. 500 Server Error — internal server error; retry after a short delay. ================================================================== 1. VDL — VIDEO DOWNLOAD LIGHT ================================================================== Recommended workflow (4 steps): 1. GET /vdl/download/info -> inspect the source URL 2. POST /vdl/download -> create a download job -> job_id 3. GET /vdl/status/{job_id} -> poll every ~2 seconds 4. GET /vdl/fetch/{job_id} -> download the finished file once status == "ready" ------------------------------------------------------------------ 1.1 GET /vdl/download/info ------------------------------------------------------------------ Price: €0.0001 per URL Purpose: Fetches metadata about a media URL — title, duration, a direct preview URL. Also detects whether the content is a slideshow/carousel (currently only supported for Pinterest and TikTok). Query parameters: url (string, REQUIRED) — full URL of the video or media page. Example: "https://youtu.be/dQw4w9WgXcQ" Response example (JSON): { "title": "Video Title", "duration": 120, "preview_url": "https://...", "is_slideshow": false, "images": ["https://...", "https://..."], "audio_url": null } cURL: curl -X GET "https://api.mehtor.ru/vdl/download/info?url=https://youtu.be/dQw4w9WgXcQ" \ -H "X-Api-Key: " Python: import requests url = "https://api.mehtor.ru/vdl/download/info" headers = {"X-Api-Key": ""} params = {"url": "https://youtu.be/dQw4w9WgXcQ"} response = requests.get(url, headers=headers, params=params) print(response.json()) ------------------------------------------------------------------ 1.2 POST /vdl/download ------------------------------------------------------------------ Price: €0.0003 per request Purpose: Creates a job to download/generate media.

Example: "550e8400-e29b-41d4-a716-446655440000" Response examples (JSON), one of: { "status": "processing" } { "status": "ready" } { "status": "error", "error": "" } cURL: curl -X GET "https://api.mehtor.ru/vdl/status/550e8400-e29b-41d4-a716-446655440000" \ -H "X-Api-Key: " Python: import requests url = "https://api.mehtor.ru/vdl/status/550e8400-e29b-41d4-a716-446655440000" headers = {"X-Api-Key": ""} response = requests.get(url, headers=headers) print(response.json()) ------------------------------------------------------------------ 1.4 GET /vdl/fetch/{job_id} ------------------------------------------------------------------ Price: €0.0005 per file. Free if the file is not yet ready or an error occurred (i.e., you are only charged when a real file is returned). Purpose: Returns the finished binary file (MP4/MP3). The link/file is only available for one hour after the job completes. Path parameters: job_id (string, UUID, REQUIRED) — the job_id obtained from /vdl/download. Example: "550e8400-e29b-41d4-a716-446655440000" Response: - If job is completed: binary file (audio/video, e.g. MP4 or MP3). - If not completed or expired: JSON, one of: { "status": "processing" } { "status": "error", "error": "" } (An "error" response here can also mean the one-hour download window has expired.) cURL (saves to file): curl -X GET "https://api.mehtor.ru/vdl/fetch/550e8400-e29b-41d4-a716-446655440000" \ -H "X-Api-Key: " \ --output video.mp4 Python: import requests url = "https://api.mehtor.ru/vdl/fetch/550e8400-e29b-41d4-a716-446655440000" headers = {"X-Api-Key": ""} response = requests.get(url, headers=headers) if response.status_code == 200: with open("video.mp4", "wb") as f: f.write(response.content) else: print(response.json()) ================================================================== 2. STT — SPEECH-TO-TEXT ================================================================== Two endpoints trade off speed vs. accuracy: - Use /STT/transcribe/fast when speed matters (e.g. real-time voice input in a game or app, live conversation translation). - Use /STT/transcribe/slow when accuracy matters (e.g. digitizing an important recording, or handling sensitive text/data that must be transcribed exactly). Both endpoints share the same request/response shape. ------------------------------------------------------------------ 2.1 POST /STT/transcribe/fast ------------------------------------------------------------------ Price: €0.000001 per second of audio Purpose: Transcribes audio using a small, fast AI model. Form-data parameters: file (file, REQUIRED) — audio file (WAV recommended). lang (string, optional) — hardcode the language code if known (e.g. "en"). If omitted, language is auto-detected. Response example (JSON): { "result": "Hello, this is a test transcription." } cURL: curl -X POST "https://api.mehtor.ru/STT/transcribe/fast" \ -H "X-Api-Key: " \ -F "file=@audio.wav" \ -F "lang=en" Python: import requests url = "https://api.mehtor.ru/STT/transcribe/fast" headers = {"X-Api-Key": ""} files = {"file": open("audio.wav", "rb")} data = {"lang": "en"} # optional response = requests.post(url, headers=headers, files=files, data=data) print(response.json()) ------------------------------------------------------------------ 2.2 POST /STT/transcribe/slow ------------------------------------------------------------------ Price: €0.000002 per second of audio Purpose: Transcribes audio using a larger, more precise (but slower) AI model. Form-data parameters: file (file, REQUIRED) — audio file (WAV recommended). lang (string, optional) — hardcode the language code if known (e.g. "ja"). If omitted, language is auto-detected. Response example (JSON): { "result": "This transcription uses a larger model." } cURL: curl -X POST "https://api.mehtor.ru/STT/transcribe/slow" \ -H "X-Api-Key: " \ -F "file=@audio.wav" \ -F "lang=ja" Python: import requests url = "https://api.mehtor.ru/STT/transcribe/slow" headers = {"X-Api-Key": ""} files = {"file": open("audio.wav", "rb")} data = {"lang": "ja"} # optional response = requests.post(url, headers=headers, files=files, data=data) print(response.json()) ================================================================== 3. TTS — TEXT-TO-SPEECH ================================================================== Choose the endpoint matching your text's language: - /TTS/en for English text - /TTS/ru for Russian text Both return a ready-to-use, copyright-free WAV file. ------------------------------------------------------------------ 3.1 POST /TTS/en ------------------------------------------------------------------ Price: €0.000001 per symbol (character) Purpose: Vocalizes English text into speech. JSON body parameters: text (string, REQUIRED) — English text to voice. Response: binary WAV audio file (Content-Type: audio/wav) cURL: curl -X POST "https://api.mehtor.ru/TTS/en" \ -H "Content-Type: application/json" \ -H "X-Api-Key: " \ -d '{"text": "Hello, this is a test."}' \ --output speech.wav Python: import requests url = "https://api.mehtor.ru/TTS/en" headers = {"X-Api-Key": ""} payload = {"text": "Hello, this is a test."} response = requests.post(url, json=payload, headers=headers) if response.status_code == 200: with open("speech.wav", "wb") as f: f.write(response.content) ------------------------------------------------------------------ 3.2 POST /TTS/ru ------------------------------------------------------------------ Price: €0.000001 per symbol (character) Purpose: Vocalizes Russian text into speech. JSON body parameters: text (string, REQUIRED) — Russian text to voice. Response: binary WAV audio file (Content-Type: audio/wav) cURL: curl -X POST "https://api.mehtor.ru/TTS/ru" \ -H "Content-Type: application/json" \ -H "X-Api-Key: " \ -d '{"text": "Hi, this is a test"}' \ --output speech.wav Python: import requests url = "https://api.mehtor.ru/TTS/ru" headers = {"X-Api-Key": ""} payload = {"text": "Hi, this is a test"} response = requests.post(url, json=payload, headers=headers) if response.status_code == 200: with open("speech.wav", "wb") as f: f.write(response.content) ================================================================== 4. MehtorSSO — SINGLE SIGN-ON ================================================================== Availability: Paid plans only. Purpose: Lets users log in with their existing Mehtor account and grant your application access to selected profile fields. Also provides a built-in secure key-value data store, scoped per user/app, for storing your own application data alongside the user's Mehtor profile. SETUP (one-time, before writing any integration code) 1. Create an application in the MehtorSSO dashboard tab to obtain a Client ID. 2. Configure your redirect URI(s): a primary URI and a fallback URI. Redirection can also be disabled entirely — in that case the user is shown a one-time code on screen and must manually enter it into your app. 3. (Optional) Create a separate API Token specifically scoped for the MehtorSSO endpoint. ------------------------------------------------------------------ 4.1 Step 1 — Build the authorization URL ------------------------------------------------------------------ Base: https://auth.mehtor.ru/ Query parameters to append: type (string, REQUIRED) — type of authorization source, e.g. "app" or "web". client_id (string, REQUIRED) — your Client ID from the MehtorSSO tab. session_id (string, REQUIRED) — a unique, one-time session identifier you generate (UUID4 recommended). Save this value — you need it later to compute the request signature. timestamp (long, REQUIRED) — current UTC time in milliseconds. need_api_token (boolean as integer 0/1, optional) — set to 1 if you want to store data in the Mehtor database / receive a per-user API token for later use (e.g. save_account_data). Set to 0 (or omit) if you don't need this. Example authorization URL: https://auth.mehtor.ru/?type=app&client_id=my_awesome_app&session_id=d174b3e1-171b-4979-a90f-b37166fd13dd×tamp=1795737600000&need_api_token=1 ------------------------------------------------------------------ 4.2 Step 2 — Redirect the user and wait ------------------------------------------------------------------ Send the user's browser/app to the authorization URL built above, then wait for them to log in (or sign up) on the Mehtor auth page. On success: - If redirection is enabled: MehtorSSO redirects the user back to your configured primary URI (or the fallback URI if something went wrong), appending a PKCE query parameter, e.g.: my_awesome_app://callback?PKCE=abcd1234 - If redirection is disabled: the user is shown a one-time PKCE code (8 characters) on screen and asked to enter it manually into your application. ------------------------------------------------------------------ 4.3 Step 3 — Exchange the PKCE code for user data ------------------------------------------------------------------ Two equivalent GET endpoints exist for this exchange — pick the one that fits where the exchange happens: A) Frontend/apps recommended method: signature-based (no server-side secret needed in the request itself). B) Backend recommended method: Bearer-token-based (uses your API token directly). --- 4.3.A GET https://auth.mehtor.ru/api/v1/get_data (frontend/apps) --- Query parameters: PKCE (string, REQUIRED) — the one-time code received via redirect or entered by the user. client_id (string, REQUIRED) — your application's Client ID. sign (string, REQUIRED) — signature of the request (see "How to build the signature" below). How to build the signature: 1. Take your Client ID and the Session ID you generated in Step 1. 2. Combine them with a minus sign: "{client_id}-{session_id}" 3. Hash that string with BLAKE2b, digest_size = 32 bytes (256 bits). 4. Use the resulting hex digest as the "sign" query parameter. Python (signature helper): import hashlib def compute_hash(client_id: str, session_id: str) -> str: data = f"{client_id}-{session_id}" data_utf = data.encode('utf-8') hasher = hashlib.blake2b(data_utf, digest_size=32) return hasher.hexdigest() Python (full request example): import requests import hashlib def compute_hash(client_id: str, session_id: str) -> str: data = f"{client_id}-{session_id}" data_utf = data.encode('utf-8') hasher = hashlib.blake2b(data_utf, digest_size=32) return hasher.hexdigest() PKCE = "YOUR_ONE_TIME_CODE" CLIENT_ID = "YOUR_CLIENT_ID" signature = compute_hash(CLIENT_ID, PKCE) # NOTE: see caveat below url = "https://auth.mehtor.ru/api/v1/get_data" params = {"PKCE": PKCE, "client_id": CLIENT_ID, "sign": signature} response = requests.get(url, params=params) print(response.status_code, response.json()) IMPORTANT CAVEAT: the signature must be computed from "{client_id}-{session_id}" using the session_id generated in Step 1 (not the PKCE code). Keep session_id available in your app's memory between Step 1 and Step 3 so you can compute this correctly. Response example (JSON): { "email": "user@example.com", "name": "John Doe", // additional fields depend on what your app requested // if need_api_token=1 was set in Step 1, you also receive: "api_token": "meh_..." } --- 4.3.B GET https://auth.mehtor.ru/api/v1/get_data (backend) --- Query parameters: PKCE (string, REQUIRED) — the one-time code. client_id (string, REQUIRED) — your application's Client ID. Headers: Authorization: Bearer (REQUIRED — your API token that has MehtorSSO listed as an allowed endpoint) Response example (JSON): same shape as method A above. cURL: curl -X GET "https://auth.mehtor.ru/api/v1/get_data?PKCE=YOUR_ONE_TIME_CODE&client_id=YOUR_CLIENT_ID" \ -H "Authorization: Bearer YOUR_API_TOKEN" Python: import requests url = "https://auth.mehtor.ru/api/v1/get_data" params = {"PKCE": "YOUR_ONE_TIME_CODE", "client_id": "YOUR_CLIENT_ID"} headers = {"Authorization": "Bearer "} response = requests.get(url, params=params, headers=headers) print(response.status_code, response.json()) ------------------------------------------------------------------ 4.4 POST https://auth.mehtor.ru/api/v1/save_account_data ------------------------------------------------------------------ Purpose: Securely save or update user data and application-specific payloads in the Mehtor database. Important: You may only update fields the user explicitly confirmed access to during authorization. Headers: Authorization: Bearer (REQUIRED — the per-user API token returned by get_data when need_api_token=1 was requested) Content-Type: application/json (REQUIRED) Request body (JSON): payload (JSON object, REQUIRED) — key-value pairs representing the fields to update in the user's account or your app's custom data space. Response example (JSON): { "status": "success", "message": "Account data updated successfully" } cURL: curl -X POST "https://auth.mehtor.ru/api/v1/save_account_data" \ -H "Authorization: Bearer USERS_API_TOKEN" \ -H "Content-Type: application/json" \ -d '{ "theme_preference": "dark", "other_app_payloads": { "my_awesome_app": { "level": 42, "pro_status": true } } }' Python: import requests url = "https://auth.mehtor.ru/api/v1/save_account_data" headers = { "Authorization": "Bearer USERS_API_TOKEN", "Content-Type": "application/json" } payload = { "theme_preference": "dark", "other_app_payloads": { "my_awesome_app": { "level": 42, "pro_status": True } } } response = requests.post(url, headers=headers, json=payload) print(response.status_code, response.json()) ------------------------------------------------------------------ 4.5 Important notes for MehtorSSO ------------------------------------------------------------------ - An authorization session (PKCE flow) is valid for only 15 minutes from the moment the authorization link is generated. - Your API Token must have the MehtorSSO endpoint explicitly allowed. - Never share API Tokens publicly; use them only from your backend. ================================================================== 5. CUSTOM ENDPOINTS ================================================================== If there is no suitable endpoint, prepare a detailed endpoint code in Python: FastAPI, and write it to the user. Suggest creating their own Endpoint in MehtorAPI via the “Add Endpoint” tab in the MehtorAPI Control Panel. You can create any type of backend here: WebSockets, P2P helper, HTTP, TCP, UDP, everything is supported. Multiplayer and VoIP included. This is free and available with any plan. ================================================================== QUICK REFERENCE TABLE ================================================================== Service | Method | Path | Price --------|--------|----------------------------------------------|------------------------ VDL | GET | /vdl/download/info | €0.0001/URL VDL | POST | /vdl/download | €0.0003/request VDL | GET | /vdl/status/{job_id} | Free VDL | GET | /vdl/fetch/{job_id} | €0.0005/file (free if not ready/errored) STT | POST | /STT/transcribe/fast | €0.000001/second STT | POST | /STT/transcribe/slow | €0.000002/second TTS | POST | /TTS/en | €0.000001/symbol TTS | POST | /TTS/ru | €0.000001/symbol SSO | GET | https://auth.mehtor.ru/ | Paid plans only (auth page) SSO | GET | https://auth.mehtor.ru/api/v1/get_data | Paid plans only SSO | POST | https://auth.mehtor.ru/api/v1/save_account_data | Paid plans only END OF DOCUMENT
