ParaSwap · Rate Limits

Rate Limits

ParaSwap (Velora) enforces rate limiting on its public REST API at https://api.paraswap.io. Specific numerical limits are not publicly documented. HTTP 429 (Too Many Requests) is returned when limits are exceeded. Exponential backoff is the recommended retry strategy. Dedicated API key holders receive higher (negotiated) throughput. The Delta API and AugustusRFQ endpoints share the same base URL and are subject to the same rate limiting policy.

Rate Limits is the machine-readable rate-limit profile for ParaSwap on the APIs.io network, conforming to the API Commons Rate Limits specification.

The profile also includes 3 backoff/retry policies defined.

Tagged areas include DeFi, DEX Aggregator, Token Swaps, Blockchain, and EVM.

Policies

Exponential Backoff
On receiving HTTP 429, clients should implement exponential backoff with jitter before retrying. This is the standard recommendation from the ParaSwap ecosystem.
Client-Side Caching
Price route responses (priceRoute objects) from /prices are valid for a short window (typically a few seconds to a minute) and should be cached client-side to reduce API call frequency.
Partner Identifier
Including a partner query parameter in API calls helps ParaSwap attribute traffic correctly and may affect priority handling for known partners.
