Every API here is available over the APIs.io API and to AI agents over MCP.
{"openapi":"3.1.0","info":{"title":"Audo API","version":"1.0.0","description":"Audio tools for people and agents: remove noise, enhance voices, transcribe, align a script, cut, remove silence, set loudness, convert, join, swap a video's audio, change speed and pitch, reverse, mute a video, convert/compress/crop/resize/reverse/loop video, find the key and BPM, and media info.\n\nFree API: POST /api/try/<tool> with a file runs the tool on the first part of it, free, a few times a day, with no account or key. For example: `curl -F file=@interview.wav https://audo.ai/api/try/remove-noise -D response.headers -o response.body`.\n\nREST API: /api/v1 runs whole files with credits (1 credit is 1 US cent). Send an API key as a bearer token (Authorization: Bearer audo_sk_…); people create keys at https://audo.ai/keys?utm_source=openapi&utm_medium=agent. Upload a file (POST /api/v1/files), start a job (POST /api/v1/jobs), wait for it (GET /api/v1/jobs/{id}?wait=30), then download the output (GET /api/v1/files/{id}/download). Files are deleted after 24 hours.\n\nEvery response carries RateLimit-Policy and RateLimit headers. Every error has the same shape: a code, a message that says what went wrong, whether to retry, and nextAction, what to do about it."},"servers":[{"url":"https://audo.ai"}],"tags":[{"name":"Free API","description":"One request per tool, free for the first part of a file, without an account"},{"name":"Tools"},{"name":"Files"},{"name":"Jobs"},{"name":"Account"},{"name":"Upload page","description":"What the upload page uses, with the token in its link, so a person can upload without signing in"},{"name":"File links","description":"Signed links to a file's bytes, on the site's own origin.
