Firehydrant Rate Limits

FireHydrant publishes a single, flat API rate limit that applies per ACCOUNT, not per key — 50 requests every 10 seconds (300 per minute), shared across every API key the organization has issued. It is not tiered by plan. This artifact replaces the 2026-05-04 scaffold, whose per-tier free/professional/enterprise numbers were invented and are not what FireHydrant publishes.

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

It captures 1 rate-limit definition, across the all tier, measuring requests.

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

Tagged areas include AIOps, Incident Management, and Rate Limiting.

Policies

Retry-After
On a 429, honor the Retry-After header, which gives the number of seconds to wait before retrying. FireHydrant does not document a remaining/reset header, so a client cannot pace itself proactively — it must react to the 429.
Shared pool
Adding API keys does not add capacity. Every key on an account draws from the same 50/10s pool, so a noisy automation starves every other integration on the org.
Read replica
https://api-read.firehydrant.io/v1 is a documented read-only host with a much longer timeout for complex reads (may lag the primary by up to 30s). The docs do not state whether it has a separate rate-limit pool.
