How this service works
Avoid paying unsafe x402 endpoints: ranked safe alternatives for the same capability.
Output
A list of up to 5 healthy sibling x402 endpoints, each annotated with settlement count, recency signals, and CDP-quality metadata to help the agent choose the best fallback route.
Example use cases
Example prompt
“The x402 endpoint I was using got blocked by preflight — can you find me up to 5 healthy alternative endpoints that handle the same task class, ranked by how recently they've had successful settlements?”
Technical details
Endpoint
POSThttps://x402station.io/api/v1/alternativesWhen to prefer
Use this endpoint when a primary x402 endpoint has been blocked by Preflight or is otherwise unavailable, and the agent needs to dynamically reroute to a healthy alternative without manual intervention. Prefer over manual catalog search when you need ranked, settlement-verified options quickly.
Side effects
- No healthy alternatives found for the given URL or task class — returns empty list
- Invalid or unrecognized URL format — returns 400 error
- Task class not recognized — returns empty or error response
- Rate limit exceeded — returns 429
- Payment not provided or insufficient — returns 402
