name: ParaSwap API Rate Limits
description: 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.

rateLimits:
  - api: ParaSwap Market API
    endpoint: GET /prices
    tier: Public (no API key)
    limit: Not published
    period: Not published
    burstLimit: Not published
    statusCode: 429
    retryHeader: Retry-After
    notes: Exponential backoff on 429 responses is recommended by downstream integrators. ParaSwap has not published specific RPS or RPM thresholds in public documentation.

  - api: ParaSwap Market API
    endpoint: POST /transactions/:network
    tier: Public (no API key)
    limit: Not published
    period: Not published
    burstLimit: Not published
    statusCode: 429
    retryHeader: Retry-After
    notes: Shares rate limit policy with the /prices endpoint. Ignoring balance/allowance checks (ignoreChecks=true) may reduce latency but does not affect rate limits.

  - api: ParaSwap Market API
    endpoint: GET /swap
    tier: Public (no API key)
    limit: Not published
    period: Not published
    burstLimit: Not published
    statusCode: 429
    retryHeader: Retry-After
    notes: Combined price + calldata endpoint; same limits as /prices and /transactions.

  - api: ParaSwap Delta API
    endpoint: GET /quote
    tier: Public (no API key)
    limit: Not published
    period: Not published
    burstLimit: Not published
    statusCode: 429
    retryHeader: Retry-After
    notes: Delta API quote endpoint. Ethereum and Base networks only.

  - api: ParaSwap Delta API
    endpoint: POST /delta/orders/build
    tier: Public (no API key)
    limit: Not published
    period: Not published
    burstLimit: Not published
    statusCode: 429
    retryHeader: Retry-After
    notes: Order construction endpoint; EIP-712 signed orders, not subject to gas.

  - api: ParaSwap Tokens API
    endpoint: GET /tokens/:network
    tier: Public (no API key)
    limit: Not published
    period: Not published
    burstLimit: Not published
    statusCode: 429
    retryHeader: Retry-After
    notes: Token list endpoint is typically low-frequency; results are suitable for caching client-side.

  - api: Dedicated API (Enterprise)
    endpoint: All endpoints
    tier: Dedicated API key
    limit: Custom (negotiated)
    period: Custom
    burstLimit: Custom
    statusCode: 429
    retryHeader: Retry-After
    notes: Higher throughput and reliability SLAs negotiated per enterprise client. Contact Velora sales for terms.

policies:
  - name: Exponential Backoff
    description: On receiving HTTP 429, clients should implement exponential backoff with jitter before retrying. This is the standard recommendation from the ParaSwap ecosystem.
  - name: Client-Side Caching
    description: 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.
  - name: Partner Identifier
    description: Including a partner query parameter in API calls helps ParaSwap attribute traffic correctly and may affect priority handling for known partners.
