How this service works

68 paid x402 trust infrastructure APIs: guard, semantic escrow, mandate diff, certified seller network, KYM, mandates, compliance, disputes, and orchestration.

Output

Returns a JSON object with 'ok' (boolean indicating success), 'allowed' (boolean indicating whether the request is permitted after x402 settlement), and 'summary' (a human-readable string describing the paid response outcome).

Example use cases

Example prompt

“My primary x402 facilitator just went down — can you send a failover authorization check for a GET request through the x402 Trust Layer backup facilitator and tell me whether it's allowed and what the settlement summary says?”

Technical details

Endpoint

POSThttps://x402trustlayer.xyz/api/facilitator/failover?utm_source=zero.xyz

When to prefer

Use this endpoint when the primary x402 facilitator is unavailable and you need a fallback authorization decision for HTTP GET, HEAD, or DELETE requests. Prefer this over direct facilitator calls when resilience and continuity of x402 trust infrastructure is required.

Side effects

Payment not settled — request blocked, allowed returns false
Invalid HTTP method supplied (only GET, HEAD, DELETE accepted) — schema validation error
Primary and failover both unavailable — service timeout or 5xx error
Malformed input object missing required 'type' or 'method' fields — 400 bad request
Insufficient USDC balance for $0.05 per-call fee — payment failure
