How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a standard JSON-RPC response object containing a 'result' field with the requested on-chain data (e.g. hex-encoded balance, block object, transaction receipt, contract return value) or an 'error' object with a code and message if the call fails.
Example use cases
Check DeFi wallet balance on-chain
“What's the current ETH balance of address 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe on Ethereum mainnet? Use the Phantom blockchain RPC to fetch the latest balance.”
Fetch transaction confirmation status
“Can you check whether transaction 0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22060 has been confirmed on Ethereum — use the Phantom API to get the transaction receipt.”
Read smart contract state for a token
“Call the totalSupply method on the USDC contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum via the Phantom RPC gateway and tell me the current total supply.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/adi/rpcWhen to prefer
Choose this endpoint when an AI agent needs raw, low-latency access to on-chain blockchain data across multiple EVM or non-EVM networks via a single pay-per-call interface, especially when you want to avoid managing node infrastructure or long-term API key subscriptions. Prefer it over free public RPCs when reliability and multi-chain coverage (57+ networks) matter, and over heavyweight indexers when you need direct node-level queries rather than pre-indexed data.
Side effects
- Invalid RPC method name returns JSON-RPC error code -32601 (method not found)
- Malformed params array causes -32602 (invalid params) error
- Unsupported network or misconfigured endpoint returns connection/timeout error
- Payment not included or insufficient USDC balance causes 402 Payment Required before the call is executed
- Rate limiting or provider downtime returns 5xx or timeout
