## 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 position-health-check-57b028c0
```

Example prompt: Check the position health on token 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — I'm holding a $500 position and my entry price was $0.0012. Tell me if I can still exit at that size and what the current rug score looks like.

## When to prefer this

Use this endpoint when you need a post-purchase, real-time combined risk assessment for an existing open position — not just entry screening. It uniquely combines exit liquidity, live P&L, and rug scoring into a single actionable verdict, making it ideal for automated hold/exit decision loops. Prefer it over individual contract or holder analysis endpoints when speed and a unified go/no-go signal matter more than granular forensics.

## Known failure modes

- Invalid or non-existent token contract address returns an error or empty result
- Token has no liquidity data, making exit assessment impossible
- Very small or illiquid tokens may have unreliable rug scores
- Missing required 'address' query parameter returns a 400-level error
- Network congestion on Base may cause stale price data
- Position size too small or too large for meaningful impact analysis

## How this service works

The post-trade check everything else skips: given a token, your position size and (optionally) entry price, returns live price & P&L, whether the position can still be EXITED at that size, and the token's current rug score — combined into a healthy / watch / exit_now verdict with reasons. The risk that changes after you buy is exactly the risk holders miss.

## Output

Returns live token price, estimated P&L (if entry price provided), a boolean or status for whether the position can be exited at the given size, the token's current rug score, and an overall verdict of 'healthy', 'watch', or 'exit_now' with human-readable reasons explaining the assessment.
