Stack Takeoff Rate Limits

STACK does not publish fixed numeric request-rate limits for its REST API v2 in its public developer materials. The documented constraints are OAuth 2.0 token lifetimes rather than per-minute request caps: access tokens are valid for 8 hours, authorization codes for 5 minutes, and refresh tokens for 90 days. Because the API is access-gated (API-Enabled Subscription or partner agreement), any concrete throttles or per-account quotas are established with STACK when credentials are issued and confirmed in the access-controlled API reference.

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

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

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

Tagged areas include Construction, Preconstruction, Takeoff, Estimating, and Rate Limiting.

Negotiated Limits
Concrete throttles and quotas are set with STACK when API credentials are issued and documented in the access-controlled reference.
