Chainstack Rate Limits

Reconciled rate limits for the Chainstack multi-chain RPC platform. Plan-based RPS ceilings, Request Unit monthly quotas, and 429 throttling on overage. Response Retry-After advised.

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

It captures 10 rate-limit definitions, across the Developer, Growth, Pro, Business, and Enterprise tiers.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, 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, quotaExceeded, and invalidAuth.

Tagged areas include Blockchain, RPC, Rate Limiting, and Quotas.
