## 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 rug-oracle-position-watch-48b810cb -d '<json body>'
```

Example prompt: I'm holding a token at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum — re-check it against my last snapshot and tell me if the risk has jumped, liquidity dropped, or the safeToTrade verdict has changed.

## When to prefer this

Use this endpoint when you have already performed an initial risk audit on a token and need to continuously monitor it for post-entry rug signals. It is specifically designed for polling held positions by diffing against a stored baseline snapshot, making it more efficient than running a full audit repeatedly. Prefer this over a full deep audit when you need lightweight, frequent monitoring rather than a one-time comprehensive review.

## Known failure modes

- Invalid or non-existent token address returns an error
- Unsupported chain value causes validation failure
- Malformed baseline snapshot object may cause diff to fail or be skipped
- Token with no on-chain liquidity data may return incomplete results
- Rate limiting or payment failure ($0.05 USDC per call) blocks the response

## How this service works

Position monitoring: re-checks a token you hold and diffs against the baseline snapshot from your previous call. Alerts on risk jumps, safeToTrade flips, liquidity drops >50%, verdict escalation. Body: {chain, address, baseline?}. Returns a fresh snapshot to store. Rugs happen after entry — poll this per held position.

## Output

A fresh risk snapshot for the token including current risk score, safeToTrade flag, liquidity level, and a diff against the provided baseline highlighting any risk jumps, verdict escalations, or liquidity drops exceeding 50%. The snapshot should be stored for use as the baseline in the next poll cycle.
