Prepaid credits · for existing keys

Prepaid credits, for keys already issued.

This page is for holders of a key already issued. Send the key as a Bearer token on a paid route: it is debited per request at list price, only when the call succeeds. Wallet-scoped routes (memory, usage) need a wallet and refuse a key.

Debited only on a successful call Never expires
Not on sale right now

We are not selling prepaid balances at the moment. Keys already issued keep working and spend down exactly as before - nothing is stranded and nothing expires.

Two ways to pay are open: pay per call from a wallet over x402 or MPP, with no account and no balance to top up, or buy a finished report by card.

keep it secret · balance at GET /api/credits/balance · agents with a wallet pay per call over x402 / MPP

How it works
# any paid tool, any language - just the header
curl -X POST -H "Authorization: Bearer a402_…" -H "content-type: application/json" \
  -d '{"domain":"example.com"}' https://agent402.tools/api/whois

# a report, the same way
curl -X POST -H "Authorization: Bearer a402_…" -H "content-type: application/json" \
  -d '{"ticker":"AAPL"}' https://agent402.tools/v1/dossier
