# Bundle Maker

> Generates curated bundles of x402-paid API endpoints from a natural-language prompt. Pay $0.01 USDC on Base mainnet per generation.

Bundle Maker takes a free-form goal ("planning a vacation", "help me hire developers", "marketing campaign for a SaaS") and returns a markdown checklist of 5–15 paid x402 endpoints — with prices, methods, and example calls — that an AI agent can chain together to accomplish the goal.

The generator endpoint is paywalled with [x402 v2](https://github.com/coinbase/x402) (`exact` scheme), settled through the Coinbase Developer Platform facilitator on Base mainnet (`eip155:8453`).

## How an agent should use this site

1. Discover the resource: `GET https://bundle-maker.vercel.app/.well-known/x402`
2. Inspect the OpenAPI spec: `GET https://bundle-maker.vercel.app/openapi.json`
3. Call the generator: `POST https://bundle-maker.vercel.app/api/generate` with body `{ "prompt": "<your goal>" }`
   - First call returns HTTP 402 with payment requirements in the `payment-required` header.
   - Pay $0.01 USDC on Base via x402 (e.g. `@x402/fetch`) and retry.
   - Successful response: `{ "markdown": "..." }`
