First Street Rate Limits

First Street's published rate limits, replacing the 2026-05-04 scaffold that carried invented free/pro/enterprise tiers. The real contract has ONE published default — 150 requests per minute — and everything else is negotiated. It also carries a second, independent ceiling most catalogs miss: a query-complexity budget of 700 that can reject a single request no matter how slowly you send them.

First Street Rate Limits is the machine-readable rate-limit profile for First Street on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 2 rate-limit definitions, across the default tier, measuring requests_per_minute and complexity_score.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Environment, Modeling, Risk, Climate, and Rate Limiting.

Policies

Contractual adjustment
Every published number is a starting point. Actual limits are set per contract and bound to the key at issuance, so two keys against the same endpoint can have different ceilings.
Playground counts against usage
Requests made through the GraphiQL Playground are ordinary API requests and count toward account usage; there is no free evaluation lane.
Tile usage counts
Map tile requests, including those made from the published Mapbox/Google Maps examples, count toward overall API usage.
