Output
Returns an analysis of the target x402 URL's payTo address indicating whether the seller is economically phantom (collects payment without delivering real value), along with supporting signals from probing the endpoint.
Example use cases
Fraud check before paying x402 API
“Before my agent pays into this x402 endpoint at https://example-x402.fly.dev/api/results, can you scan it to see if the payTo address looks like a phantom seller or a legitimate service?”
Auditing new x402 marketplace listings
“I'm building a directory of x402 APIs — can you run a phantom seller scan on https://new-provider.fly.dev/product/data-feed to check if it's actually delivering value or just collecting payments with no substance?”
Agent self-protection before spending
“My agent is about to call an x402-gated endpoint at https://mystery-x402.fly.dev/product/report — scan it first and tell me if the payTo looks economically phantom so I can decide whether to proceed.”
Technical details
Endpoint
GEThttps://geld-machen-x402.fly.dev/product/phantom-seller-scanWhen to prefer
Use this endpoint when an AI agent or developer needs to verify the legitimacy of an x402-gated API before authorizing payment — especially when encountering unknown or newly listed x402 providers in the wild. Prefer this over generic URL fingerprinting when the specific concern is economic fraud or phantom payTo detection in the x402 ecosystem.
Side effects
- Missing or invalid 'url' parameter returns an error
- Target URL is not an x402 endpoint — scan may return inconclusive results
- Network timeout if target host is unreachable
- False negatives if a phantom seller mimics legitimate response patterns
- No response schema defined — output structure may vary
