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, conforming to the API Commons Rate Limits specification.
It captures 4 rate-limit definitions, measuring compute_units_per_second and compute_units.
The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.
Tagged areas include Web3, Blockchain, RPC, NFT, and Indexing.
