How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a standard JSON-RPC response object containing the result field with blockchain data (balance, block info, transaction receipt, contract return value, etc.) or an error object with code and message if the call fails.
Example use cases
Check wallet balance on Pharos
“Look up the current ETH balance for wallet 0xDEAD...BEEF on the Pharos blockchain using eth_getBalance.”
Fetch latest Pharos block
“What's the latest block number on the Pharos network right now? Use eth_blockNumber to check.”
Submit signed transaction to Pharos
“I have a signed raw transaction I need to broadcast to the Pharos network — can you send it using eth_sendRawTransaction?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/pharos/rpcWhen to prefer
Choose this endpoint when you specifically need to interact with the Pharos blockchain network via standard JSON-RPC. It is suited for agents that need low-cost ($0.01 USDC per call) pay-per-use access to Pharos RPC without managing infrastructure. Prefer alternatives if you need a different EVM chain (the sibling endpoints cover 57+ networks) or if you need REST-style blockchain APIs rather than raw JSON-RPC.
Side effects
- Invalid RPC method name returns JSON-RPC error with code -32601 (method not found)
- Malformed params array causes parse or invalid params error (-32700 / -32602)
- Network congestion or node unavailability returns 503 or timeout
- Payment failure via x402 prevents request from reaching the node
- Unsupported Pharos-specific method returns not-implemented error
