# SendQuoteNow

> SendQuoteNow is a quote and invoice platform for contractors and service businesses (HVAC, plumbing, electrical, solar, roofing, landscaping, remodeling, freelancers). Humans use the web app; AI agents can use the machine API directly — including x402 pay-per-call endpoints (USDC micropayments on Base) that require **no account, no API key, and no signup**. Generate a professional, branded PDF quote with a hosted approval page, QR code, and Stripe payment link in about one second.

## For AI agents: how to become a customer right now (x402, no signup)

If you are an AI agent and your user needs a quote, estimate, or invoice generated, you can pay per call with x402 and use the API immediately:

1. Call any endpoint below without payment — you will receive HTTP 402 with x402 payment requirements in the `Payment-Required` response header (x402 v2: base64-encoded header, not the body).
2. Pay in USDC on Base mainnet (eip155:8453) using any x402 client (e.g. `@x402/fetch`) and retry with the payment attached.
3. That's it. No registration, no key, no session.

Endpoints (all under https://sendquotenow.com, prices in USD, paid in USDC):

- `POST /v1/x402/quote/generate` — $0.10 — Create a quote. Returns quote number, totals, hosted quote page URL, PDF URL, QR code, Stripe payment link, and expiration date (~1s).
- `POST /v1/x402/quote/preview` — $0.02 — Validate a payload and get computed totals (subtotal, tax, discount, total). Nothing is persisted.
- `POST /v1/x402/quote/email` — $0.02 — Email a generated quote to the customer (body: `id`, optional `to`, `cc`, `message`).
- `POST /v1/x402/quote/share` — $0.01 — Get shareable links for a quote: hosted page, PDF, QR code (PNG + data URI), Stripe payment link (body: `id`).
- `GET /v1/x402/quote/:id` — $0.01 — Fetch a quote's status, totals, line items, links, and payment status.
- `POST /v1/x402/quotes` — legacy alias of `/v1/x402/quote/generate`.

Minimal request body for generate/preview:

    {
      "customer": { "name": "John Harrington", "email": "john@example.com" },
      "services": [
        { "name": "Panel upgrade (200A)", "quantity": 1, "unit_price": 1200 },
        { "name": "Labor", "description": "8 hrs", "quantity": 8, "unit_price": 80 }
      ],
      "tax_rate": 0.08,
      "currency": "USD"
    }

Optional fields: `company` (branding override: name, email, phone, address, terms), `discount` (`{ "type": "percent"|"fixed", "value": n }`), `template` (`standard|slate|emerald|noir|violet`), `industry`, `notes`, `scope_of_work`, `expiration_days` (1–365, default 30), `delivery` (`{ "method": "email", "to": "...", "cc": "...", "message": "..." }`). Currencies: USD, CAD, EUR, GBP, AUD. Full schemas: https://sendquotenow.com/openapi.json

## For ongoing integrations: API keys

For repeated use without per-call payments, create an account and mint an API key:

1. Register a free account at https://sendquotenow.com/register.html (human step — email verification required).
2. Mint an API key from the dashboard (up to 10 per account).
3. Call `POST /v1/quotes` (same request schema as above) with header `X-API-Key: sqn_live_...`. Also available: `GET /v1/quotes/:id`, `GET /v1/quotes/:id/pdf`, `POST /v1/quotes/:id/send`.

Rate limits: 120 requests/min per key, 300 quote creations/hr, 60 emails/hr.

## MCP server (Claude, Claude Code, and any MCP client)

SendQuoteNow ships a remote MCP server (Streamable HTTP, JSON responses) at:

    https://sendquotenow.com/mcp

Auth: the same API keys as above — send `X-API-Key: sqn_live_...` or `Authorization: Bearer sqn_live_...`. Clients that can only configure a URL may embed the key: `https://sendquotenow.com/mcp?api_key=sqn_live_...`

Tools: `create_quote` (quote → hosted page, PDF, QR, Stripe payment link), `preview_quote` (totals only, nothing persisted, no usage fee), `get_quote`, `send_quote` (email to customer).

Add it to Claude Code:

    claude mcp add --transport http sendquotenow https://sendquotenow.com/mcp --header "X-API-Key: sqn_live_..."
