## 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 unlock-calendar-e182b8df
```

Example prompt: Pull up the token unlock calendar for ARB over the next 180 days — I want to see the next unlock date and amount, the full cliff and linear unlock schedule, how the allocation breaks down between team, investors, and ecosystem, and what the supply-overhang score is.

## When to prefer this

Use this endpoint when you need forward-looking tokenomics data for a specific crypto token — especially unlock schedules, vesting timelines, allocation breakdowns, and supply-pressure scoring. Prefer this over generic price or market-cap APIs when the question involves future supply changes, investor unlock risk, or vesting cliff events. The supply-overhang score makes it uniquely useful for pre-investment due diligence or trading timing decisions. Best when you know the ticker, name, or DeFiLlama slug of the token.

## Known failure modes

- Token not found — unrecognized ticker, name, or slug returns an error or empty result
- Ambiguous ticker — multiple tokens share the same symbol, may require using the slug parameter instead
- No upcoming unlocks in window — token may be fully vested or have no scheduled events in the requested period
- DeFiLlama data unavailable — upstream data source may be stale or missing for obscure tokens
- window_days out of range — values below 1 or above 1825 will fail schema validation

## How this service works

Forward-looking token unlock and vesting calendar for one crypto token. Give a ticker, name or slug and get the next unlock (date, token amount, USD value, percent of circulating supply), the full list of upcoming cliff and linear unlocks in a window, the allocation split across team, investors, ecosystem and community, supply metrics and a deterministic 0-100 supply-overhang score. Data from DeFiLlama, cited.

## Output

Returns a structured object containing: the next unlock event (date, token amount, USD value, % of circulating supply), a list of upcoming cliff and linear unlocks within the requested window, allocation percentages across team/investors/ecosystem/community buckets, supply metrics (circulating, total, max supply), and a deterministic 0-100 supply-overhang score indicating potential sell pressure risk. Data is sourced from DeFiLlama.
