verify_address
shallowtech.interpretai/PostAgent · Verify this server
Standalone paid address verification — no mail is sent. Checks whether an address is deliverable and returns the standardized form (US: CASS with ZIP+4; international: per-country matching). Costs a small flat USDC fee per call via x402 (a fraction of a cent vs. mailing). Two-step flow, like the mail rails: call WITHOUT `paymentSignature` to get the 402 challenge and `paymentUrl` (preferred: have the agent's x402 wallet pay `paymentUrl` in-band with the address as the JSON POST body `{"address":{...}}`); or sign the challenge and call again WITH `paymentSignature` to verify and get the result in one round trip. US addresses need line1 + (city+state or zip). International addresses need line1 + country. Note: when mailing through PostAgent you do NOT need this tool — create_mail_quote already verifies sender and recipient for free as part of the quote.
