Spire Maritime · Rate Limits

Spire Maritime Rate Limits

The Spire Maritime 2.0 GraphQL API applies a per-token request quota documented as up to 60 requests per minute per token (burst 60). Each GraphQL response reports remaining quota under extensions.requestQuota with a limit string (e.g. "60 req/m (burst 60)") and a remaining count. The raw TCP AIS stream is a continuous push feed rather than a per-request API, so it is governed by contract throughput/coverage rather than an RPM limit. Exact contractual limits vary by agreement.

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

It captures 4 rate-limit definitions, measuring requests, records, and messages.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Vessel Tracking, AIS, Maritime, GraphQL, and Rate Limiting.

Policies

Quota Reporting
GraphQL responses expose remaining quota inline via extensions.requestQuota so clients can self-throttle.
Backoff Strategy
Clients should implement exponential backoff with jitter on 429 responses and honor any Retry-After.
