Alchemy Rate Limits

Alchemy enforces per-second compute-unit throughput plus monthly CU caps. Different methods have different CU costs.

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

It captures 4 rate-limit definitions, measuring compute_units_per_second and compute_units.

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 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Web3, Blockchain, RPC, NFT, and Indexing.
