## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-signals-momentum-endpoint-crypto-market-intelligence-x402-a7e8f94d
```

Example prompt: What's the current momentum signal for SOL — give me the RSI, recent returns, and whether it's in a bullish, neutral, or bearish regime.

## When to prefer this

Use this endpoint when an AI trading agent needs a quick, pay-per-call momentum assessment for a specific crypto asset without a subscription. Ideal for autonomous agents that need RSI, trend regime, and return data in a single call, especially when operating on x402 micropayment rails. Prefer this over full-featured exchange APIs when cost-per-call economics matter and the agent only needs signal data, not order execution.

## Known failure modes

- Missing or invalid 'symbol' query parameter returns a 400 error
- Unknown or unsupported asset symbol may return an error or empty result
- Payment not settled via x402 protocol results in 402 Payment Required response
- Network or upstream data source outage may return 500 or timeout
- Symbol provided in wrong format (e.g. 'BTCUSD' instead of 'BTC') may yield unexpected results

## How this service works

Pay-per-call crypto market-intelligence API for autonomous AI trading agents. Funding-rate, BTC lead-lag and trend/chop regime signals, settled in USDC over x402.

## Output

A JSON object containing the base asset symbol, 1-hour RSI value, a categorical signal (e.g. neutral/bullish/bearish), percentage returns over 1h/24h/7d, and a human-readable interpretation string summarizing the momentum picture.
