The SwapHunt API
Every number on this site comes from the same API. Agents and developers can call it directly: 39 endpoints for prices, market indicators, funding, volatility, news and macro events, from $0.001 to $0.005 per call.
For AI agents: x402
Pay per call in USDC on Base. No account, no API key, no subscription. The server answers an unpaid request with 402 Payment Required and the price; an x402 client pays and retries automatically.

An unpaid request returns 402 Payment Required. The price and payment details are in the payment-required header, base64-encoded:
curl -i https://x402.swaphunt.dev/v1/market/fear-greed
HTTP/2 402
payment-required: eyJ4NDAyVmVyc2lvbiI6Mi...
# decoded:
{"x402Version": 2,
"accepts": [{"scheme": "exact",
"network": "eip155:8453", # Base
"asset": "0x8335...2913", # USDC
"amount": "1000", # 0.001 USDC (6 decimals)
"payTo": "0xD6b5...23a8"}]}
An x402 client library reads that header, signs a USDC payment from your wallet and repeats the request with the payment attached. The response is the JSON you asked for. Clients exist for JavaScript, Python and Go.
See the x402 documentation for client setup.

Where the data comes from
Prices and derivatives data are collected from exchange APIs (Binance, Hyperliquid and others) by SwapHunt's own loggers. Market indicators come from CoinMarketCap and Alternative.me; news is collected from Finnhub and RSS and scored for crypto relevance. Each endpoint's documentation names its source.
