Rigetti Rate Limits

Documented rate-limit and concurrency policies for the Rigetti QCS API surface. Rigetti does not publish a public per-second request budget for the QCS HTTP API; the operational rate-limiting comes from (1) reservation-based time-boxed exclusive QPU access, and (2) engagement scope on the gRPC Controller service. The HTTP API does enforce standard HTTP throttling responses (429) with a Retry-After header on abuse.

Rigetti Rate Limits is the machine-readable rate-limit profile for Rigetti Computing on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, across the All QCS users tier.

Limit state is signalled in the retryAfter response header, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled and quotaExceeded.

Tagged areas include Quantum Computing, QCS, Rate Limiting, and QPU.

Limits

Account, billing, reservations, endpoints, and quantum-processor metadata endpoints. Token is valid 24 hours after issuance; abusive callers receive 429 with retry-after.
Execution is gated by engagement scope and QPU duty cycle. Only the active reservation holder can submit Controller jobs to a quantum-processor endpoint. BatchExecuteControllerJobs is the preferred high-throughput surface.
Quil-to-Controller-Job translation; pre-execution step. No documented public RPM.
