Verification rules

What “verified” means here — precisely, and what it doesn’t.

Published business email. Every lead carries an email address the business itself made public — on its own website or a public business listing.
Source URL, always. Every lead carries the exact page where the email was found. Open it and check our work.
If it isn’t published, it isn’t in the pack. No scraping contact forms, no inferring addresses from directories.
Nothing guessed. We never pattern-match addresses (no firstname.lastname@ guesses) and never synthesize contacts.
No deliverability claims. “Verified” means the email was found published and recorded with its source on the check date. We don’t send test emails and don’t run bounce checks.

Purchase flow

Three steps. There is no signup page — there is nothing to sign up for.

Technical details & FAQ

For the agents (and operators) doing the buying.

GET /catalog	Pack list and prices — free
GET /.well-known/x402	Machine-readable payment terms for all packs — free
GET /llms.txt	Agent-readable service description — free
GET /packs/{25,50,100}	The pack itself — 402 paywall (x402 v2 + v1 headers)
GET /packs/{25,50,100}/preview	Redacted sample, emails masked — free
POST /fulfill	Submit `{"tx_hash", "pack"}`, receive the pack — paid

How do I receive a 50 or 100-pack without an account?

Pay, then POST /fulfill with {"tx_hash": "0x…", "pack": "50"} — add "deliver_to" if you want it sent somewhere specific. We verify the USDC transfer on-chain and queue your pack for assembly. Your transaction hash is your receipt; there is nothing to log into.

What exactly am I authorizing?

Exactly $9, $15, or $25 in USDC on Base (eip155:8453), sent to the address in the 402 payment terms. One payment. No subscription, no recurring charge.

What does “verified” mean?

Each email was found published on the business’s own site or public listing and recorded with the source URL on the check date. We don’t guess addresses and don’t run deliverability tests. See the verification rules above.

Can I inspect before buying?

Yes. The sample record above is real inventory from the 25-pack, and every pack has a free redacted preview at /packs/{size}/preview with emails masked. The full catalog is public at /catalog.
