Polygon errors

Polygon methods return upstream errors in the standard JSON-RPC {jsonrpc,id,error} envelope. Triport's own product errors (auth, tier, rate limit) are plain HTTP responses decided before the RPC layer — see the shared error reference.

Endpoint and plans: Polygon RPC endpoint.

Notable method-page behavior:

  • bor_*, trace, and txpool methods can return HTTP 403 tier_insufficient when their feature or tier gate is not enabled;
  • HTTP 429 rate_limited means the category budget and burst were exhausted; honor Retry-After and retry with backoff;
  • malformed calls, block selectors, tracer configs, and Polygon-native params return -32602;
  • an unknown or orphaned block hash can validly return result: null; handle it separately from the error envelope.
