0X Rate Limits

Rate limit envelope for the 0x API surface. Rates are scoped per API key (issued via dashboard.0x.org) and shared across all product surfaces (Swap, Gasless, Cross-Chain, Trade Analytics, Sources). Values reflect the public commercial pricing tiers documented at https://0x.org/pricing.

0X Rate Limits is the machine-readable rate-limit profile for 0x on the APIs.io network, in the API Commons Rate Limits shape.

It captures 5 rate-limit definitions, across the free, standard, custom, and any tiers, measuring requests_per_second, seconds, and stream_duration_seconds.

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 serviceUnavailable.

Tagged areas include Cryptocurrency, DeFi, DEX Aggregator, Rate Limiting, and Quotas.
