deadchannel x402 Risk Probe
x402
deadchannel x402 Risk Probe is a paid API for AI agents from deadchannel.vercel.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Probes an x402 payment-gated endpoint and returns a risk verdict (live, degraded, trap, testnet, or dead), a 0-100 risk score, and the specific problems found — before spending money on it.

How this service works
Use before paying an x402 endpoint you have not used before, when you cannot tell a working seller from a trap, a testnet address dressed as mainnet, or a listing whose price no longer matches its challenge. Returns a verdict — live, degraded, trap, testnet or dead — a 0-100 risk score, and the specific findings behind both, so an agent can decline a bad endpoint instead of learning about it by losing the money. Costs less than the smallest payment it protects.
Output
Returns a verdict string (one of: live, degraded, trap, testnet, dead), a numeric risk score from 0 to 100 (higher = riskier), and a list of specific problems detected with the endpoint — allowing the caller to decide whether to proceed with a paid call.
Example use cases
Pre-flight check before automated spending
“I'm about to wire up my agent to call https://payments.someservice.com/report via GET — can you run a quick deadchannel probe with 2 samples first and tell me if it's live, degraded, or a trap before I burn any USDC?”
Vetting a newly discovered x402 API
“I found this x402 endpoint on agentic.market — https://api.newprovider.xyz/stream — can you probe it with 5 samples and give me its risk score and verdict so I can decide if it's worth integrating?”
Diagnosing a failing paid endpoint
“My agent keeps getting weird responses from https://data.flakyprovider.io/feed using POST — can you run a deadchannel risk check on it with 3 probes and tell me what specific problems it finds?”
Technical details
Endpoint
POSThttps://deadchannel.vercel.app/probeWhen to prefer
Use this endpoint whenever you are about to call an unknown or untrusted x402 payment-gated resource and want to avoid wasting funds on dead, degraded, or malicious endpoints. It is especially valuable in automated agent workflows where multiple x402 APIs are discovered dynamically (e.g. from a marketplace) and need pre-screening before budget is committed. Prefer it over blindly calling the target endpoint when the cost of a failed or fraudulent call exceeds $0.001 USDC.
Side effects
- Target URL is unreachable or times out during probing
- Invalid URL format returns a validation error
- Samples value outside 1-5 range may be rejected or clamped
- The probe itself may be blocked by the target endpoint's rate limiting or firewall
- Ambiguous results if the endpoint has intermittent availability during the probe window
