x402 Endpoint Check | Blackwood — v1 x402-check
Limited track record
How we rate this
Delivery health: unknown. Paid successes: 0. Paid failures: 0. Schema confidence: high.
Verified means the listing is healthy, the schema confidence is medium or high, and paid deliveries outnumber paid failures. Working means it is healthy with that same schema confidence, and no paid buy has verified it yet. Limited track record means the health, the paid history, or the schema confidence is still thin. Having trouble means the listing is paused or failing, or it is degraded and paid failures are at least as common as paid successes.
Use when you need an x402 endpoint check or x402 endpoint test, or to validate x402 endpoint listings before paying or integrating.
