Web search for trading bots, priced per call

Crypto trading bots live on fresh information: ETF flows, funding rates, exchange listings, macro headlines, protocol exploits. Traditional news and search APIs sell that as a monthly subscription with an API key to babysit — a bad fit for a bot that searches in bursts around volatility and sits idle the rest of the day.

The x402 Search API charges $0.01 USDC per call. Your bot pays only when it actually searches. No account, no key, no subscription — the payment is the credential.

Example: checking ETF flows

POST https://x402.eleeth.com/api/search
{"query": "bitcoin ETF net inflows today", "num_results": 5}

{
  "provider": "exa",
  "query": "bitcoin ETF net inflows today",
  "results": [
    {"title": "...", "url": "...", "snippet": "..."}
  ]
}

How your agent pays

1. POST https://x402.eleeth.com/api/search with no payment header → HTTP 402 with payment requirements.
2. Your agent signs a $0.01 USDC transfer and retries with the X-PAYMENT header.
3. Payment is verified on-chain, results return as JSON.

Any x402 v2 client library (@x402/core / x402-fetch) handles this automatically.

FAQ

Which network? Base mainnet. Same API either way.

Are there rate limits? No published rate limits — call when the market moves.

Why not a monthly news API? If your bot searches 2,000 times a month, that's $20 in per-call fees and zero subscription overhead. Bursty workloads win on per-call pricing.
