## 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 project-legitimacy-scan-45f96a0f -d '<json body>'
```

Example prompt: Can you do a legitimacy scan on the token project called GreyFi with contract address 0x4f3a...b12c — I want to know if it looks structurally credible or if there are red flags in its claims?

## When to prefer this

Use this endpoint when you need a quick, affordable ($0.25) structural credibility check on a token project before deeper research or investment — especially useful for flagging obvious red flags, validating project claims, or screening new or unfamiliar tokens. Prefer this over manual whitepaper review when speed matters and you want a cached or live fast read rather than a deep audit.

## Known failure modes

- Unknown project name or token address returns insufficient data for assessment
- Invalid token address format causes input validation error
- Project too new or obscure to have meaningful structural signals
- Cache miss combined with live fetch timeout results in delayed or empty response
- Ambiguous project name with multiple matches may return results for wrong project

## How this service works

Fast structural + claims legitimacy read on a token project, cache-or-live.

## Output

Returns a fast structural and claims-based legitimacy assessment of the queried token project, including credibility signals, potential red flags, and an overall legitimacy read — sourced from cache if previously scanned, or live if not.
