Signal Engine is a signal-generation service targeting short-term crypto trading agents that need pre-computed, strategy-specific entry signals before placing or evaluating a trade. It exposes four distinct technical strategies as separate endpoints, each returning a structured signal payload with risk parameters. It serves agents that need to select a strategy by ID and symbol, then act on the returned direction and levels. It does not provide portfolio management, order routing, historical backtests, or multi-asset coverage beyond BTC, ETH, SOL, and DOGE.

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
Make my x402 API at https://signal-engine-production-d88d.up.railway.app discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://signal-engine-production-d88d.up.railway.app --json`. Heads up: 3 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
