How this service works
Use when an agent wants to test a third-party endpoint for a 402 challenge, latency and response shape without paying it. Returns One bounded x402 endpoint request and payment-flow evaluation. $0.01.
Output
Returns a structured evaluation of the submitted x402 endpoint task and payment flow, including a quality score, pass/fail verdict, and feedback on correctness of the request and payment configuration.
Example use cases
Pre-launch x402 integration check
“I'm about to go live with my x402-gated API. Can you run an evaluation on this endpoint task and payment flow to see if everything is configured correctly and tell me the quality score?”
Debugging a failing x402 payment request
“My x402 endpoint keeps failing — can you evaluate this specific request and payment flow and tell me what's wrong with it?”
Scoring a new endpoint for Bazaar listing
“I want to list my endpoint on the x402 Bazaar — can you evaluate this task and payment flow request and give me a quality assessment so I know if it's ready?”
Technical details
Endpoint
POSThttps://api.oblique.markets/api/v1/paid/endpoint-task-evaluation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically evaluate a single x402 endpoint task and its associated payment flow — particularly when validating integration correctness before listing on the x402 Bazaar, debugging payment configuration issues, or assessing task quality scores. It is purpose-built for x402 protocol evaluation and payment-flow analysis, unlike general API testing tools.
Side effects
- Invalid or malformed request payload returns a 400 error
- Payment not received or incorrect USDC amount causes rejection
- Endpoint URL unreachable or misconfigured results in evaluation failure
- Missing required x402 payment headers cause authentication errors
- Rate limiting or quota exceeded returns a 429 error
