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 (block data, balance in wei, transaction hash, contract return value, etc.) or an error object with code and message if the call fails.
Example use cases
Check Celo wallet balance
“What's the CELO balance of address 0x1234567890abcdef1234567890abcdef12345678 right now? Use the Celo RPC to call eth_getBalance.”
Fetch latest Celo block
“Get me the latest block on the Celo blockchain — I need the block number, timestamp, and transaction count.”
Broadcast signed Celo transaction
“I have a signed raw transaction hex for Celo — can you submit it to the network using eth_sendRawTransaction and give me the transaction hash?”

POSThttps://synapse-api-brown.vercel.app/api/celo/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call Celo RPC access without managing your own node or committing to a subscription. It's ideal for infrequent or agent-driven Celo blockchain interactions billed in USDC via x402, covering all standard eth_* and net_* JSON-RPC methods on the Celo network.
Side effects
- Invalid JSON-RPC method name returns error code -32601
- Malformed params array causes parse error -32602
- Payment failure (402) blocks request if USDC not available
- Network congestion or Celo node downtime causes timeout
- Submitting to wrong network (e.g. Ethereum mainnet method quirks) returns unexpected results
