# LeadFuzion Agent Store

> Buy LeadFuzion historical lead packages (Probate, FirstUp) per purchase, with no account. One package = one item_id. Each package has a fixed price, the same with or without skip tracing; the price is shown free before any charge, and nothing is priced below $0.50.

## What is sold
- Product type: Historical packages only. Lead types: Probate, FirstUp.
- Prices come from the quote (GET /api/v1/packages/{item_id} or the get_package_quote tool), never from this file.
- Every paid call needs a buyer attestation: buyer (who is buying, with a contact), purpose, accept_terms=true and the quote's terms_version. It is recorded with the order.

## MCP
- Endpoint: https://mcp.leadfuzion.ai/api/v1/mcp (Streamable HTTP, JSON responses; protocol 2026-07-28 and 2025-11-25). initialize, server/discover and tools/list are free and need no auth.
- list_packages (free): List lead packages for sale
- get_package_quote (free): Get price and details for one package
- buy_package (paid): Buy a lead package
- Without payment, buy_package returns the price and how to pay (x402 requirements in structuredContent, MPP challenges in result._meta "org.paymentauth/payment-required"); nothing is charged.

## HTTPS
- GET https://mcp.leadfuzion.ai/api/v1/packages?state=&county=&lead_type=&limit= (free)
- GET https://mcp.leadfuzion.ai/api/v1/packages/{item_id} (free quote)
- POST https://mcp.leadfuzion.ai/api/v1/packages/{item_id}/purchase with JSON {buyer, purpose, accept_terms, terms_version} (paid; answers 402 until paid)
- POST https://mcp.leadfuzion.ai/api/v1/orders/redeem with JSON {order_token} (redelivery, no charge; the token goes in the body, never the URL)
- POST https://mcp.leadfuzion.ai/api/v1/orders/recover with JSON {payment_nonce, issued_at, signature} (x402 payers who lost the order_token: sign 'LeadFuzion order recovery\nx402 payment nonce: <nonce>\nissued_at: <issued_at>' with the paying wallet; never pay twice for one order)
- OpenAPI: https://mcp.leadfuzion.ai/openapi.json

## How to pay
- Card (MPP, method=stripe): retry the purchase with `Authorization: Payment <credential>` built from the 402's WWW-Authenticate challenge, e.g. `npx @stripe/link-cli mpp pay '<purchase url>' -X POST -d '<json body>'`.
- Stablecoin on Tempo (MPP, method=tempo): pay the tempo challenge, e.g. `tempo request -X POST --json '<json body>' '<purchase url>'`.
- USDC on Base (x402 v2, scheme exact): sign the PAYMENT-REQUIRED requirements and retry with the PAYMENT-SIGNATURE header (any x402 v2 client, e.g. purl or Coinbase Payments MCP 'Make an x402 request').
- Every paid response carries an order_token and its order_token_expires_at. If your MCP client cannot pay inside MCP, pay at the HTTPS purchase URL, then call buy_package with item_id and order_token to get the records in the conversation.
