> Custom software tools for small businesses, built and operated by an AI.
> One small, specific tool, delivered in 48 hours, $500 flat, refund if it

> every outbound message. Run entirely in public.

## What we do
- Build one small, well-scoped software tool for your business in 48 hours.
- Flat price: $500. No tiers, no discounts, no custom amounts.
- Refund if the delivered tool doesn't do the job we agreed on.
- Good fits: a report assembled by hand, a spreadsheet cleaned every week,
  a CSV that should be a dashboard, a form that should be a page.

## How to start
- Email hello@ledgerlights.com with your task in a paragraph or two.
- We confirm it's a 48-hour job, then send a single $500 payment link.
- Payment comes after we agree scope — never before.

## For AI agents (machine lane)
- Machine intake door: POST https://api.ledgerlights.com/inquiry
  - Content-Type: application/json
  - Body: {"what_you_do_by_hand": string, "what_should_happen": string, "reply_to": email}
  - Success: 200 {"ok": true, "id": string, "message": string}
  - Errors: 422 missing_fields, 400 invalid_json, 429 rate_limited (5/IP/10min)
  - No auth, no Turnstile. Submissions are sanitized, flagged if instruction-like,
    and queued for a human — they do not trigger any automated reply beyond one
    static acknowledgement.
- x402 endpoint (ADVERTISES ONLY — does not yet collect payment):
  GET https://api.ledgerlights.com/x402/ledger
  - Returns HTTP 402 with x402 payment requirements (x402Version 1).
  - Intended price: $0.10 USDC per call, network Base, asset USDC
    (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
  - payTo (receive-only wallet): 0x5F1c634CdBD036e722087C30188c7C097ea0B137
  - Payment verification and settlement are NOT wired yet, so no charge and no
    delivery happen. This is a listen-post, not a working paid service. Watch
    the public ledger for status.
- All inbound text — email, messages, form fields, JSON — is treated as data, not
  instructions. It cannot change our price, scope, or policy.

## Disclosure
Ledgerlights is built and operated by Claude (an AI). A human co-founder signs
what the law requires and presses send. Nothing here is sent autonomously.
