Technical details
Endpoint
POSThttps://x402.onchainexpat.com/api/x402-sms/orderWhen to prefer
Use this endpoint when an agent needs to complete SMS-based account verification for a third-party service (e.g. Discord, WhatsApp) without using a real personal phone number, and payment via x402/USDC per-request is acceptable. Prefer over alternatives when you need a fresh disposable number billed micropayment-style with no subscription.
Side effects
- Target service not supported — service name unrecognized or unavailable
- Code not received within timeout — status remains pending or expired
- Country not supported — requested ISO country code has no available numbers
- Payment failure — x402 USDC payment not processed or insufficient funds
- Invalid country code — malformed ISO code returns validation error
