How this service works
Preflight an agent RPC or x402 chain-data request before payment: endpoint origin, method risk, chain fit, price, and budget checks.
Output
Returns a structured preflight advisory including: endpoint origin safety verdict, method risk classification, chain/network compatibility result, price evaluation, and budget sufficiency check — helping the agent decide to proceed, warn, or block the request before any payment is made.
Example use cases
Budget guard before paid RPC call
“Before my agent sends a paid eth_call request to the Base mainnet RPC endpoint https://mainnet.base.org, preflight it to make sure the method risk is low, the chain is Base, the price is $0.005 USDC, and that stays within my $0.50 daily budget.”
Block risky write method before execution
“My agent is about to call eth_sendRawTransaction on an unknown RPC origin — can you run a preflight check on it first to see if the endpoint is safe, what the method risk level is, and whether I should block the call?”
Verify chain fit for cross-chain agent task
“I have an agent trying to read chain data from what it thinks is Polygon but the RPC origin looks unfamiliar — preflight the request to confirm the chain ID matches Polygon mainnet and that the endpoint origin is legitimate before any payment goes through.”
Technical details
Endpoint
GEThttps://nohands-coinbase-bazaar.bytoken2023.workers.dev/v1/x402/agent/rpc-preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is about to make a paid x402 or RPC chain-data call and needs a pre-execution safety gate — especially when the endpoint origin is unfamiliar, the method could be destructive (write/send), the chain identity needs confirmation, or budget enforcement is required. Prefer this over the budget-route planner when you need a single-request go/no-go decision rather than multi-step routing.
Side effects
- Invalid or unreachable RPC origin URL returns an origin safety failure
- Unknown or unsupported chain ID returns a chain fit mismatch error
- Missing required parameters (origin, method, chain, price, budget) returns a 400 bad request
- Price exceeds declared budget returns a budget-exceeded block result
- Unrecognized RPC method returns an unknown method risk warning
