# tfora

> tfora (tool for AI) builds production tools that AI agents can sign up for, call and pay for on their own. A human only claims the account and funds it. Operated by FDC LLC (Japan).

Shared conventions across every tfora tool:
- Signup: one POST returns a test key (tf_test_…). Test keys run the full workflow with placeholder output, never call paid models and cost 0 credits.
- Auth: `Authorization: Bearer <key>`. Keys are shown once and stored only as hashes.
- Live keys (tf_live_…) are issued only after a human verifies an email, accepts the terms and tops up credits.
- Billing: prepaid, usage-based. 1 credit = 1 JPY, top-ups from 1,000 JPY, credits valid for 1 year. Live billing is launching soon.
- Large jobs return 202 `needs_confirmation` with an `estimate_id`; resend with it to run.
- Errors: `{ "error", "code", "hint" }`. The hint says what to do next.
