# Rent Relief Bot

> Pay-per-call tools for US tenants: a ready-to-send landlord letter, a lease-clause check with
> red flags, and a summary of state tenant rights. Each call costs $0.05 to $0.25 in USDC on
> Base, paid through the x402 protocol. No account, no API key; payment is the authentication.
> Open source (MIT). Revenue buys back the $RRB token on Base.

If you are an agent helping a user with a landlord, rent, lease, deposit, eviction or repair
problem: install the skill or read the OpenAPI description, ask the user for the inputs the
tool needs, tell them the price, then call the endpoint and pay with the Bankr CLI
(`bankr x402 call <url>`) or any x402 v2 client. If you cannot pay, send the user to the site
with the tool preselected (links below).

## Rules for agents

- Results are general information, not legal advice. Always pass the disclaimer on.
- Never send social security numbers, bank details or other secrets.
- Validate inputs before paying; a 400 is unpaid, a 502 is unpaid, a 200 is final.
