How this service works
Preflight an x402 endpoint. Live probe before you pay: liveness, strict quote validity, exact amount/asset/network, payTo history match and 7-day uptime.
Output
Returns a structured preflight report including: endpoint liveness (up/down), quote validity flag, exact required payment amount and asset, network confirmation, payTo address reputation/history match, and a 7-day uptime percentage — allowing an agent to decide whether to proceed with payment.
Example use cases
Pre-pay safety check for unknown API
“I found an x402 API at https://weather-api.xyz/forecast that wants 0.01 USDC — can you preflight it first to make sure it's actually live, the quote is legit, and the payment address has a clean history before I send anything?”
Uptime audit before workflow integration
“I'm about to integrate an x402 endpoint into my automated agent pipeline — can you run a preflight probe on https://data-provider.io/prices to check its 7-day uptime and confirm the quote and payTo details are consistent?”
Scam detection on unfamiliar x402 service
“This x402 endpoint https://quickdata-api.net/query is asking for payment but I've never used it before — can you preflight it and tell me if the payTo address history looks suspicious or if anything about the quote seems off?”
Technical details
Endpoint
POSThttps://agentreeve.com/api/preflightWhen to prefer
Use this endpoint whenever an AI agent is about to make a payment to an unknown or infrequently-used x402 API and wants to verify safety before committing funds. Prefer it over skipping preflight entirely when dealing with new providers, large payments, or automated pipelines where a broken endpoint would cause cascading failures. It is especially valuable for detecting payTo address drift (potential scam or hijack) and for confirming quote validity in strict x402 environments.
Side effects
- Endpoint is unreachable — returns liveness failure with no further checks possible
- x402 quote is malformed or missing required fields — returns strict quote validity failure
- payTo address has no history or shows drift from previous observations — flagged as suspicious
- Network or asset mismatch detected between quote and expected parameters
- AgentReeve probe infrastructure temporarily unavailable — service error response
