How It Works
2
Real Payment Test
We make an actual paid request to the API using the x402 protocol. This ensures we're testing the real experience users will have.
3
AI Evaluation
GPT-5.2 analyzes the response to determine if it's valid, useful, and worth the price. The AI considers response quality, accuracy, and value proposition.
4
Score & Status
Each API receives a quality score (0-100) and verification status. This data is displayed on resource cards and detail pages.
Understanding Scores
✓
Verified (80-100)
Excellent quality. The API returns valid, useful data and provides good value for the price.
?
Needs Review (60-79)
Acceptable but may have issues. The response was valid but quality or value could be better.
✗
Failed (<60)
Quality concerns. The API may have returned errors, invalid data, or poor value for the price.
?
Pending
Not yet verified. New resources are typically verified within 24 hours of being discovered.

Frequently Asked Questions
How often are APIs re-verified?
APIs are re-verified periodically, typically every 24-48 hours for active resources. If an API starts failing checks, it will be flagged more quickly.
What does "Paid" mean in the verification history?
When you see a "Paid" badge, it means our system actually paid for and executed a real request to test the API. This ensures authentic testing conditions.
Can I request a re-verification?
Currently, re-verification happens automatically. If you're a seller and believe your API was incorrectly scored, please contact support.
Why is my API showing as "Pending"?
New APIs are verified within 24 hours of discovery. If your API has been pending longer, it may be unreachable or have configuration issues.
What AI model is used for evaluation?
We use GPT-5.2 to analyze API responses. The AI evaluates response validity, usefulness, accuracy, and whether the value matches the price.
