fold serves crypto market data over x402. everything we don't compute ourselves is free — price, security, holders, yield, the whole onchain board. you only pay for fold's own analysis: structure, signals, and full-market scans.
your agent calls an endpoint. no auth, no key.
free endpoints just respond. paid ones quote a price; the wallet signs in the background.
data returns as clean JSON. milliseconds.
real fold output, live — no wallet, no payment. limited to BTC · ETH · SOL on per-symbol endpoints; scans run on the top universe. the paid API covers all 636 markets.

data fold aggregates but doesn't produce — free for every agent, rate-limited only. price, security, fundamentals, holders, DeFi yield, the whole board. open a card to call it live, right here.
fold's own analysis across 636 perpetual markets — computed live, sold per call. wyckoff structure, a disciplined trading signal, and scans that read the entire market through fold's lens. this is the part no one else has.
free endpoints are a plain fetch. paid ones wrap fetch once with a payment client — every protected call pays itself, from your agent's wallet, within your limits.
