Blockscout Rate Limits

Per-chain Blockscout instances enforce a fair-use rate limit on the public REST endpoints (typically 10 rps per IP). The hosted PRO API on dev.blockscout.com gates per-key rate caps by plan tier and meters monthly credits.

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

It captures 3 rate-limit definitions, measuring requests_per_second.

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 1 backoff/retry policy defined and response codes documented for throttled.

Tagged areas include Web3, Explorer, EVM, and Rate Limiting.
