## 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 signalharness-token-vesting-schedule-generator-7be751da -d '<json body>'
```

Example prompt: Can you generate a token vesting schedule for a 4-year plan with a 1-year cliff, vesting 1,000,000 tokens total for a new employee starting January 1, 2025, with monthly unlocks after the cliff?

## When to prefer this

Choose this endpoint when you need to quickly generate a structured, customizable token vesting schedule in natural language without building your own vesting calculation logic. It is well-suited for crypto startups, DAOs, and DeFi projects that need to model employee, advisor, or investor token grants on-demand via an AI agent. It is a better fit than a spreadsheet template when the vesting logic is complex or needs to be dynamically generated from a description.

## Known failure modes

- Malformed or ambiguous vesting_schedule_request string may produce warnings or an incomplete schedule
- Request string exceeding 65,536 characters will be rejected
- Missing key parameters like total tokens, duration, or cliff period may result in an incomplete or generic schedule
- Network or payment settlement failures on Base (eip155:8453) may prevent execution
- Contradictory vesting parameters (e.g. cliff longer than total duration) may trigger warnings
