risk data for machine payments
Endpoint
rpc.nodeflare.app/data/balances/x402
Multi-chain balances API: native + ERC-20 token balances for one address across up to 17 EVM chains (Ethereum, Base, Arbitrum, Optimism, BNB, and young chains like Robinhood, Ink that Alchemy/Moralis omit) in a single request. Pay per call in USDC, no account or API key - built for AI agents. Priced about $0.0003 per chain.
The live price in the envelope is higher than the catalogue price. An agent holding a “no more than a cent” limit compares that limit against the price it was just sent, not against the price that was promised — so it pays.
More than a twofold gap gives block; anything smaller
gives warn with the exact percentage.
prepay verdict
in that case is warn: unknown is a risk, not a clean bill of health.Recent probes

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
