## 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 token-unlock-vesting-schedule-lookup-3ca18f11 -d '<json body>'
```

Example prompt: Pull the next token unlock schedule for Arbitrum — I want to see the upcoming unlock dates, how many tokens are unlocking, the USD value, and what category each unlock falls into, up to the next 10 events.

## When to prefer this

Use this endpoint when you need detailed token vesting and unlock schedule data for a specific protocol, including upcoming dates, amounts, USD values, and unlock categories. Prefer this over generic market data endpoints when the specific goal is to anticipate supply-side pressure from token unlocks or to monitor vesting schedules for investment timing decisions.

## Known failure modes

- Unknown or unsupported protocol slug returns an error or empty result
- Protocol slug misspelled or not recognized
- No upcoming unlock events scheduled returns empty events list
- External data source unavailable causes timeout or 500 error
- Exceeding limit of 20 events may return capped results or error

## How this service works

Token unlock / vesting schedule for a protocol: next unlock date, token amount, USD value, category and type, plus upcoming events. Send { protocol } (slug, e.g. "aptos", "arbitrum"). Large unlocks are the most reliable supply-shock catalysts — front-run sell pressure.

## Output

Returns the next unlock date, number of tokens unlocking, USD value of the unlock, the category (e.g. team, investor, ecosystem) and type of unlock, plus a list of upcoming vesting events (up to the requested limit, default 5, max 20) for the specified protocol.
