Grok Crypto Quant API

● down crypto

Pay-per-call crypto quant tools for agents, paid in USDC over x402: strategy backtests and parameter optimisation on Coinbase daily candles with a survivorship-bias-free point-in-time universe, daily market signals, point-in-time top-N universes, and token contract risk checks (Base, Ethereum, Solana).

Paid verification

How it works

No sponsored paid call yet.

Pay this endpoint once from your own wallet (Base USDC, up to $1.00) and we call it and record what came back. Your wallet pays the listed recipient directly; Agent Tools never holds funds. Sponsored checks prove delivery; they do not count as demand.
