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.

A JSON-RPC response object containing the result field (on-chain data, transaction hash, block info, etc.) or an error object with code and message if the call fails
Example use cases
Query on-chain wallet balance
“Check the ETH balance for wallet 0xAbCd...1234 on Ethereum mainnet right now — use the degen RPC and give me the result in wei.”
Fetch latest block number
“What's the current block number on the Polygon network? Use the Synapse degen RPC to call eth_blockNumber for me.”
Broadcast signed transaction
“I have a signed raw transaction hex I need to submit to the Arbitrum network — can you broadcast it using eth_sendRawTransaction via the degen RPC?”

POSThttps://synapse-api-brown.vercel.app/api/degen/rpcWhen to prefer
Choose this endpoint when you need to make arbitrary JSON-RPC calls against one of 57+ supported blockchain networks on a pay-per-call basis without managing your own node infrastructure. It is ideal for DeFi agents, blockchain data pipelines, or transaction broadcasting workflows that require broad multi-chain coverage with minimal setup.
Side effects
- Invalid or unsupported RPC method name returns an error response
- Malformed params array causes a parse or invalid params error
- Unsupported chain or network returns a routing error
- Payment failure via x402 results in a 402 Payment Required response
- Rate limiting or node unavailability returns a 5xx server error
- Transaction broadcast failure returns an RPC error with revert reason
