Access

API keys

Keys are shown once at creation — store them somewhere safe. Revoking is instant and can't be undone.

All keys

Name	Token	Created	Last used

Data policy per key

Every key is sealed by default — audio in, metrics out, nothing retained for training. Sealed keys are covered by our BAA. Healthcare workloads should stay sealed.

Good hygiene

Scope one key per environment, rotate quarterly, and never ship a sk_live key in client-side code.

Real-time speech analysis

v1

Docs

Fluency, pacing, and clarity metrics in minutes. Authenticated endpoints require a signed-in session or a Bearer token.

Authentication

Pass your key as a bearer token. Test keys (sk_test_) hit the sandbox; live keys (sk_live_) are metered. When signed in on this console, requests can reuse your session's ID token instead.

Authorization: Bearer sk_live_xxxxxxxxxxxx

POST /v1/analyze

Upload an audio file, get back metrics. Max 25 MB; wav, mp3, m4a, ogg, flac.

audio	file, required — the recording to analyze
metrics	array — any of fluency, pace, clarity, onsets
baseline_id	string — score against a stored speaker baseline

Request

curl https://api.stutterstep.ai/v1/analyze \
  -H "Authorization: Bearer $STUTTERSTEP_KEY" \
  -F "audio=@session.wav" \
  -F 'metrics=["fluency","pace","clarity"]'

Response

{
  "fluency": 0.87,
  "pace_wpm": 142,
  "clarity": 0.91,
  "duration_s": 318.4
}

GET /v1/sessions

List analyzed sessions for a speaker — week-over-week deltas measured against their own baseline, never a population norm.

Request

curl "https://api.stutterstep.ai/v1/sessions?speaker=spk_8d2&weeks=8" \
  -H "Authorization: Bearer $STUTTERSTEP_KEY"

Errors

Errors return a JSON body with a machine-readable code and a human message. Honor Retry-After on 429.

401	missing or invalid bearer token
413	audio exceeds the 25 MB limit
422	unsupported codec or malformed request
429	rate limited — back off and retry

Playground

Send a live request to the public /health endpoint — no auth required. Authenticated endpoints like /v1/analyze need a signed-in session or a bearer token; sign in to try those.
