## 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 x402-catalyst-protocol-search-f3d59977 -d '<json body>'
```

Example prompt: Search for crypto protocols with tracked token-unlock schedules whose names contain 'arb' — I need the slug so I can look up their unlock calendar.

## When to prefer this

Use this endpoint when you know the name (or partial name) of a crypto protocol and need to discover the correct slug to pass to the catalysts/unlocks endpoint. This is a prerequisite search step before fetching actual token-unlock schedule data. Prefer this over guessing slugs directly.

## Known failure modes

- Empty results if no protocol name matches the substring query
- No results returned for very short or ambiguous query strings
- Rate limit or payment failure if USDC payment of $0.02 is not provided via x402 protocol
- Malformed request if query field is missing from request body
- Limit exceeding 100 may be rejected or capped

## How this service works

Find protocols that have tracked token-unlock schedules, by name substring. Send { query }. Use the returned slug with catalysts/unlocks.

## Output

A list of matching protocols (up to the specified limit, default 20) with their names and slugs that can be passed to the catalysts/unlocks endpoint to retrieve full token-unlock schedule data.
