Endpoint
POSThttps://synapse-api-brown.vercel.app/api/stable/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single pay-per-call RPC interface that spans AI processing, web scraping, and multi-chain blockchain queries without managing separate API keys or SDKs — especially useful for agents that need to switch between data domains dynamically and want micropayment-based billing via x402.
Side effects
- Invalid or unsupported method name returns a JSON-RPC error object
- Malformed params array causes a parameter validation error
- Payment not provided or insufficient USDC results in HTTP 402 response
- Unsupported blockchain network identifier returns a network-not-found error
- Rate limiting or timeout on slow external data sources may return a timeout error
