How this service works
x402-Email Spec v0.1 verifier (paid lane). Validates a sender address, accountability bond, and x402 payment header from an inbound email and returns a routing recommendation (inbox | review | spam). Same input as the free public endpoint at /api/x402/email/verify; this lane adds a signed _x402 receipt for bazaar callers. Live on Base mainnet.
Output
Returns a routing recommendation of 'inbox', 'review', or 'spam' based on the sender's email address, on-chain accountability bond, and x402 payment header validity. The paid lane additionally returns a signed _x402 receipt suitable for bazaar callers on Base mainnet.
Example use cases
Example prompt
“Check whether this inbound email from alice@example.com with her x402 payment header and accountability bond should go to inbox, review, or spam — I need the signed receipt for the bazaar.”
Technical details
Endpoint
POSThttps://theloopbreaker.com/api/x402/trust/email-verifyWhen to prefer
Use this endpoint over the free /api/x402/email/verify endpoint when you need a cryptographically signed _x402 receipt alongside the routing recommendation, especially for bazaar callers or downstream agents that require verifiable proof of the verification. Prefer this when operating within the x402-Email Spec v0.1 ecosystem on Base mainnet and when auditability of the spam/inbox decision is required.
Side effects
- Invalid or missing x402 payment header — payment not submitted or malformed
- Sender address not found or unresolvable — verification fails
- Accountability bond not present or insufficient on-chain — routed to spam
- Base mainnet RPC unavailable — service degraded or timeout
- Malformed request body — 400 error returned
- Payment amount insufficient ($0.01 USDC required) — request rejected
