Signal API — Pair Trading Intelligence for AI Agents

01 / Overview

Accordion is a cointegration-based pair trading bot that has been running live for 2+ months. The Signal API exposes its analytical engine as programmable endpoints.

Every signal is grounded in Engle-Granger cointegration testing and z-score mean reversion. The engine classifies market regimes, computes hedge ratios, and generates entry and exit signals. You decide how to size and execute.

Two access modes: x402 micropayments for AI agents (USDC on Base L2, no subscription needed), and API key subscriptions for developers building trading systems.
