Most agents will not buy from this endpoint.
0 of 6 agents would pay
GET /.well-known/x402.json did not return a JSON object. A buying agent has no way to learn what this endpoint sells, what it costs, or how to call it without a human reading the site.
Fix
Serve a JSON discovery document at /.well-known/x402.json describing the resource, its price and its parameters.
Requesting the resource without payment did not return 402 Payment Required, so an agent cannot discover the price by asking.
Fix
Return 402 with an x402 challenge when a request arrives without payment.
The 402 response body did not parse as a JSON object, so its terms cannot be read programmatically.
Fix
Return the challenge as JSON.
The first entry of `accepts` carries no numeric `maxAmountRequired`, so an agent cannot tell what the call costs before making it.
Fix
State the amount in `accepts[].maxAmountRequired`.
The discovery document declares no same-origin sample, so an agent cannot see the shape of what it is buying before it pays.
Fix
Declare a free sample response in `resources[].sample`.
A deliberately invalid request did not answer with a 4xx status. An agent cannot distinguish its own mistake from a broken service, so it cannot retry intelligently.
Fix
Return 4xx for invalid input, reserving 5xx for genuine server faults.
Price is not stated plainly; documentation only mentions a freemium model with no API pricing information disclosed.
No sample response available and no machine-readable API contract provided; cannot validate endpoint functionality before integration.
Discovery endpoint returns 404 with no machine-readable API specification, pricing details, or sample responses available for evaluation.
