## How to call it through Zero

```sh
zero fetch --capability tradeos-tech-150618aa -d '<json body>'
```

Example prompt: Pull the TradeOS signal evidence pack for BTC — I want to see the full breakdown of why this signal deserves attention, including the market regime check, order-flow stress, forecast context, freshness, and any risk flags before I add it to the validation queue.

## When to prefer this

Choose this endpoint when an agent or analyst needs a complete, explainable evidence packet for a specific crypto signal — especially in validation queues that require structured justification before escalating a signal. Prefer this over raw signal feeds when the consumer needs reasons, regime context, and risk flags rather than just a raw long/short call.

## Known failure modes

- Invalid or unrecognized token symbol returns an error with no evidence packet
- Signal not found or too stale returns a freshness failure with no context
- Payment of $1 USDC not completed results in 402 Payment Required
- Missing required parameters returns a 400 validation error
- Market data unavailable for the requested token returns partial or empty evidence fields

## How this service works

A review-ready evidence packet for bots, dashboards, and analysts that need to understand why a crypto signal deserves attention. It joins the current signal state with forecast context, market-regime checks, order-flow stress, freshness, disagreement drivers, and risk flags. Built for validation queues that need evidence, not another unexplained long/short call.

## Output

A structured JSON evidence packet containing the current signal state, forecast target zones, market regime assessment, order-flow stress metrics, signal freshness indicators, disagreement drivers, and risk flags — providing full context for why a signal merits review without issuing trade instructions.
