## 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 messari-token-unlocks-asset-discovery-dc7b3dd5 -d '<json body>'

Example prompt: Can you pull a list of all crypto assets on Messari that have tracked token unlock schedules, so I can see which ones have upcoming unlock dates and amounts?

## When to prefer this

Use this endpoint when you need to discover and enumerate which crypto assets have token unlock schedules tracked by Messari, before drilling into per-asset unlock details. It is the right starting point for building dashboards, screening assets for unlock risk, or identifying which tokens to monitor for vesting events. Prefer this over the per-asset endpoint when you don't already know the asset slug or want to survey the full universe of tracked projects.
