Access and keys

The API is for businesses and broadcasters. Every plan is agreed with you, and comes with keys and monthly limits.

Getting access

  1. Contact us with what you want to build and roughly how much: how many words a month, how many hours of live signing, how many videos.
  2. Most start with a trial: about a month with modest limits, to try Signa on your own content.
  3. We agree your plan, and you get live keys with the limits of your plan.

Using a key

Send it as a bearer token on every request:

curl https://api.usesigna.org/v1/api/me \
  -H "Authorization: Bearer $SIGNA_KEY"
KeyMeaning
sk_live_…A live key, with the limits of your plan.
sk_trial_…A trial key. It stops working on the trial's end date.

You can have several keys, for example one per product, station or environment, all counting against the same plan. Ask us for another at any time.

We can't show a key twice

We only store a fingerprint of each key, so nobody at Signa can read it back to you. If a key is lost or leaks, tell us: we revoke it at once and issue a new one.

Monthly limits

Your plan sets up to three monthly limits. A limit that is not set means no limit.

LimitWhat counts
CharactersThe characters of every text you sign, through /v1/sign or /v1/spoken-to-signed-pose.
Live minutesTime connected to /v1/live.
VideosEvery video made with /v1/sign/video.

Months are calendar months in UTC. When a limit is reached, requests that need it are refused with 429 API_LIMIT_REACHED until the 1st, or until we raise it. Errors and limits.
