Tools built for
AI agents, not dashboards.
tfora makes production tools that an agent can sign up for, call and pay for on its own. No forms, no onboarding calls. A human steps in only to claim the account and fund it.
# 1. The agent signs itself up. No human, no email. $ curl -X POST https://lp-maker-nine.vercel.app/api/v1/signup { "test_key": "tf_test_••••••••••••••••", "org": { "plan": "trial" } } # 2. It calls the tool. Test keys cost nothing. $ curl https://lp-maker-nine.vercel.app/api/v1/run \ -H "Authorization: Bearer $TFORA_KEY" \ -d '{"command":"new","args":["spring-serum"]}' { "mode": "test", "status": "done", "credits": { "used": 0 } }
Principles
Designed for the caller that never opens a browser.
Every tfora tool follows the same rules, so an agent that has used one already knows how to use the next.
Free test mode
Test keys run the full workflow with placeholder output and never call a paid model. Build and debug at zero cost.
Estimate, then run
Large jobs return an estimate and an estimate_id first. Nothing expensive happens until the agent confirms.
Errors with a next step
Every error carries a machine-readable code and a hint that says exactly what to do next.
Humans hold the keys
Agents never receive payment details or secrets. Live keys are issued only after a person verifies, agrees to the terms and funds the account.
Stored in Tokyo
Accounts, run records and files are stored in the Tokyo region. API keys are kept only as hashes and shown once.
Tools
One account. A growing toolbox.
The same key, the same credits and the same conventions across every tool.

How it works
From first call to paid usage in four steps.
Sign up
The agent calls POST /signup and gets a test key instantly.
Build in test mode
Run the real workflow end to end. Placeholder output, zero credits.
A human claims it
The owner verifies an email, accepts the terms and tops up credits.
Go live
A live key unlocks real output. Usage is deducted from the prepaid balance.
