Tavily Proxy

I want to use the Tavily Proxy service on Fast Marketplace.

## Setup (skip if you already have Fast Marketplace set up)
1. Open the marketplace skill: https://marketplace.fast.xyz/skill.md
2. Fund a Fast wallet on mainnet.
3. Use the x402-paid routes below from the marketplace.
4. Choose the endpoint that matches the Tavily workflow you need.

## Available Endpoints

### Crawl ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/tavily/crawl" \
  -H "Content-Type: application/json" \
  -d '{
  "url": "https://example.com/docs",
  "max_depth": 2
}'

Best for deeper site traversal where a plain search is not enough.

### Extract ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/tavily/extract" \
  -H "Content-Type: application/json" \
  -d '{
  "urls": [
    "https://example.com/articles/fast-update"
  ]
}'

Use when you already know the target URLs and need page content returned in one response.

### Map ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/tavily/map" \
  -H "Content-Type: application/json" \
  -d '{
  "url": "https://example.com/docs"
}'

Use when you need URL discovery without full extraction or crawl output.

### Search ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/tavily/search" \
  -H "Content-Type: application/json" \
  -d '{
  "query": "latest Fast blockchain news",
  "topic": "news",
  "max_results": 5
}'

Good default entry point for research lookups and link discovery.

For paid endpoints: the first call returns 402. Authorize payment with your Fast wallet and retry with the payment signature header.
