# Saylor Innovations Token Vesting Schedule Calculator

> Saylor Innovations Token Vesting Schedule Calculator is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Computes a full token vesting schedule from allocation, cliff, vesting duration, TGE unlock, and start date — returning tokens unlocked today, locked remainder, next unlock date, and the complete monthly release table.

## 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 saylor-innovations-token-vesting-schedule-calculator-d644322d
```

Example prompt: Can you calculate the full token vesting schedule for an allocation of 5,000,000 tokens, with a 12-month cliff, 36 total vesting months, 10% unlocked at TGE, starting January 1 2024 — and tell me how many are unlocked as of today and when the next unlock is?

## When to prefer this

Use this endpoint when you need a precise, deterministic token vesting schedule computation given explicit vesting parameters — total allocation, cliff, duration, TGE unlock, and start date. It is ideal for portfolio tracking agents, investor dashboards, or token analysis workflows that need both a current unlock snapshot and the full forward-looking monthly schedule. Prefer it over manual spreadsheet calculations or generic finance APIs that do not understand TGE mechanics or cliff-based crypto vesting structures.

## Known failure modes

- Missing required parameters (total_tokens, vest_months, start_date) returns a 400 error
- Invalid date format for start_date or as_of causes a parsing error
- Non-numeric values for total_tokens or vest_months may cause computation failure
- tge_percent values outside 0-100 may produce nonsensical results
- Very large token allocations or very long vesting periods may cause precision issues in floating-point output

## How this service works

Token vesting from total allocation, cliff, vesting months, TGE unlock and start date: tokens unlocked today, locked remainder, next unlock and the monthly schedule.

## Output

Returns a JSON object with: the evaluation date, number of tokens unlocked to date, tokens still locked, cliff date, vesting end date, next unlock date and amount, and a complete array of monthly schedule entries each containing the release date, months since start, tokens unlocked that month, cumulative tokens unlocked, and cumulative percent unlocked. Also includes a plain-language note and source attribution.
