How this service works
HALOWERK x402werk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns the health and availability status of one or more x402 payment facilitators (cdp, xpay, x402org), and optionally indicates whether a specified blockchain chain (by CAIP-2 identifier such as eip155:8453) is supported by those facilitators.
Example use cases
Pre-payment facilitator readiness check
“Before I trigger any x402 payments, can you check if the cdp facilitator is healthy and if Base Mainnet (eip155:8453) is currently supported?”
Monitor all x402 facilitators
“Run a health check on all known x402 facilitators — cdp, xpay, and x402org — and tell me which ones are currently up.”
Chain support verification
“I need to know if eip155:8453 is supported by the xpay facilitator before I route my payment through it — can you check?”
Technical details
Endpoint
POSThttps://x402.netzhandwerker.de/facilitator/healthWhen to prefer
Use this endpoint when you need to verify x402 payment facilitator availability before routing a payment, when building monitoring or alerting for x402 infrastructure, or when you need to confirm that a specific blockchain (by CAIP-2 ID) is supported by one or more facilitators. Prefer this over generic uptime checkers because it understands x402-specific facilitator semantics and chain support.
Side effects
- Facilitator unreachable — returns unhealthy or error status for that facilitator key
- Invalid CAIP-2 chain identifier format — may return validation error or unsupported chain response
- Payment failure (0.003 USDC required per call) — request rejected if payment not provided
- Unknown facilitator key supplied — may be ignored or return error
- Network timeout accessing upstream facilitator endpoints
