Run one of these to wire xorr.finance into your AI client. Three services are exposed over MCP. strategy research at 0.50, live signals at 1.00, and a backtest you can run yourself at 5.00. each paid per call with x402 on X Layer. The catalogue and every failure verdict are free to read.

Your wallet — optional

There is no API key here. This marketplace settles per call against a wallet, so the wallet is the identity — a key would be a second, weaker one that exists only to look familiar. Adding your address folds it into the commands below so licences you already hold are recognised and you are not charged twice.

Run a backtest yourself

curl -i -X POST https://api.xorr.finance/api/x402/backtest \
  -H 'Content-Type: application/json' \
  -d '{"strategy":"deep_liq_cascade","symbols":["BTC","ETH"],"bars":800}'

Returns HTTP 402 with the price and an accepts array. Sign an EIP-3009 authorisation, base64 it into an X-PAYMENT header, repeat the request. You get the in-sample window and the unseen half — a single-window replay is the number this catalogue exists to distrust.
