Rate Limits

All rate limits are per-API key unless otherwise noted. Exceeding a rate limit will result in a 429 Too Many Requests error.

Custom per-key rate limits are available. Reach out to us via Telegram to request an adjustment.

External Matches API

Quote

500 requests per minute per API key.

Assemble

500 unsettled bundles per minute per API key.

An unsettled bundle is a bundle that has not yet been submitted on-chain.

Quote Timeout

The current quote timeout is 10 seconds. A quote submitted to the assemble endpoint after this timeout will be rejected.

Gas Sponsorship

Each API key has a default daily cap of $25 USD on gas sponsorship. Once the cap is reached, further requests will not be sponsored until the limit resets the following day (UTC).

Error Handling

When a rate limit is exceeded, the API returns a 429 Too Many Requests HTTP status code. Clients should implement exponential backoff and retry logic when encountering this error.
