Free tier · one call per day · no card
Get your own free-tier quota
The free Santos tools allow one call per day per identity. Without a token that identity is the calling IP — and Claude, Grok, and every other hosted agent reach the API from shared infrastructure, so that single call is spent by whoever gets there first. A token moves the quota onto you.
Issue a token
One 6-digit code by email. The token is valid 30 days, carries one free call per day, and needs no account or card.
Why the IP quota runs out
A hosted agent does not call from your machine — it calls from its provider’s servers. Every user of that platform shares those addresses, so they share one daily free call. Raising the limit would not fix it; the identity is the problem, which is why the token exists.
When you outgrow free
One call a day is for evaluation. Paid endpoints have no quota at all — they settle per call in USDC on Base over x402, with no account and no API key, and a failed call is never charged. See the docs or buy a formatted report if you would rather not run a wallet.
