Pricing & plans

Plan limits are enforced on every API key at api.polyorderbooks.com. Your key inherits the tier on your account.

Checkout for paid plans (Pro, Scale) is rolling out soon. Until billing is live, new accounts receive Starter (free). Contact us for Enterprise or early Pro access.

What limits mean

Rate limits

Per minute — rolling window; when exceeded, responses are HTTP 429 with a Retry-After header (seconds).
Per day — counted in UTC; resets at midnight UTC.

Monitor usage with GET /v1/usage or the dashboard.

Resolution floor

Open markets are captured every 1 second. Your plan controls the finest resolution you may request:

Starter — down to 60s (or 1m, same bucket size).
Pro / Scale / Enterprise — down to 1s.

Requesting 1s on Starter returns HTTP 403.

History window

start_ts cannot be older than your plan’s lookback from now (UTC). Violations return HTTP 403 with the earliest allowed timestamp in the message.

Example — Starter usage response
