x402
agenteconomy.cloud x402 Endpoint Diagnostics is a paid API for AI agents from mcp.agenteconomy.cloud, paid per call via x402, $1/call, status unknown (last checked 2026-09-15).
Runs a live paid test purchase against an x402 endpoint, identifies the exact payment flow failure, and benchmarks the endpoint's price against on-chain category demand data.

How this service works
Listed but never paid? One call answers why. We run a real paid test purchase against your x402 endpoint (not a lint) and name the exact fault when the flow breaks — 402-again loops, invalid_payload, malformed accepts. Then the half no linter has: your category's actual on-chain demand — who earns, the median price paid, your price against it. Signed, recomputable verdict from the trust hub that indexes every Bazaar seller's payment history. agenteconomy.cloud (mcp-pricing-v1.1)
Output
A signed, recomputable verdict containing: the exact named fault in the payment flow (e.g. 402-again loop, invalid_payload, malformed accepts header), payto address match/mismatch finding, the endpoint's advertised price vs the category median price paid on-chain, who earns in the category, and overall on-chain demand metrics for the endpoint's market segment.
Example use cases
Debug 402-again payment loop
“My x402 endpoint at https://api.myservice.com/premium keeps returning 402 even after payment goes through — can you run a live test against it and tell me exactly what's failing? My payto address should be 0xDEF456... and I'm charging 1000 micro-USDC.”
Price benchmarking before launch
“I'm about to list my x402 data endpoint at https://api.myanalytics.com/feed for 750 micro-USDC — can you test it end-to-end and tell me how that price stacks up against what others in my category are actually earning on-chain?”
Audit payto address mismatch
“Something feels off with my x402 integration at https://api.myagent.com/query — I think it might be charging to the wrong wallet. Can you run a real purchase test against it and check whether the payto address matches 0x9F1a2B...? I'm advertising at 200 micro-USDC.”
Technical details
Endpoint
POSThttps://mcp.agenteconomy.cloud/api/v1/diagnoseWhen to prefer
Choose this endpoint when you need to go beyond static linting and run an actual paid end-to-end test of an x402 payment flow. It is uniquely suited when you suspect a 402-again loop, invalid_payload, or malformed accepts error that a linter cannot surface, or when you need real on-chain pricing intelligence — median prices paid and category demand — rather than self-reported figures. Prefer it over generic x402 validators when you want a signed, recomputable verdict backed by the full Bazaar seller payment history index.
Side effects
- Endpoint URL is unreachable or returns non-402 status unexpectedly
- Advertised price in micro-USDC is below the minimum recognized entry, falling back to live quote
- Payto address mismatch detected but expected_payto was not provided so mismatch goes unconfirmed
- x402 endpoint has no category match in the on-chain index, making price comparison unavailable
- Service itself cannot complete the paid test due to network or chain issues
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| endpoint | string | https:// resource URL of the x402 endpoint to diagnose (pre-catalog endpoints welcome — findability reports honestly) |
| expected_payto | string | optional 0x… address you expect the endpoint to charge to; mismatch is a named finding |
| asserted_price_micro | integer | your advertised price in micro-USDC — becomes the price basis vs the category median; defaults to the live quote's cheapest recognized entry |
