## 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 cryptointel-trade-signal-598e7441
```

Example prompt: Give me a trade signal for BTC — I want to know whether to buy, sell, or hold, along with the RSI, trend, momentum, and whether there are any insider red flags.

## When to prefer this

Use this endpoint when an agent needs a fast, opinionated trade signal with both technical indicators and insider/narrative context for a specific crypto token, especially when a confidence score and plain-language reasoning are required for downstream decision-making.

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Unknown or unsupported ticker may return no data
- Service unavailability on Railway hosting returns 5xx
- Payment failure or insufficient USDC balance returns 402
