How this service works
Cryptocurrency technical analysis for AI agents and developers: 24 indicators, candlestick patterns, summary ratings and live tickers, paid per call in USDC via the x402 protocol. No API keys, no subscription.
Output

Example use cases
Real-time RSI overbought signal check

Choose SignalBrew when you need on-demand, per-request cryptocurrency technical indicator calculations without maintaining your own candle database or indicator computation logic. It is ideal for agents that need current indicator values for trading decisions, alerting, or signal generation, and can pay micro-amounts per call in USDC via x402. Prefer it over self-hosted solutions when low-latency, pay-as-you-go access to pre-synced exchange candle data is needed.
Side effects
- Unsupported exchange or symbol returns a 4xx error
- Unsupported indicator name returns a 4xx error
- Invalid interval string causes a bad request error
- Payment failure via x402 protocol blocks the request
- Insufficient candle history for the requested length may return an error or partial result
- Network timeouts if market data sync is lagging
