# Delx Vesting Remaining

> Delx Vesting Remaining is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Calculates how many tokens remain unvested at a given point in time given a linear vesting schedule with optional cliff

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 delx-vesting-remaining-c72de133 -d '<json body>'
```

Example prompt: A grant of 1000 tokens started vesting on Jan 1 2024 and ends on Jan 1 2026 with a 6-month cliff — how many tokens are still unvested as of today, July 1 2025?

## When to prefer this

Use this endpoint when you need a fast, stateless computation of linear token vesting progress without building the math yourself — especially inside agent workflows that evaluate grant or treasury vesting at arbitrary points in time. Prefer this over custom code when you need consistent, auditable vesting math with cliff support in a single API call. Not suitable for non-linear or cliff-with-immediate-percentage vesting models.

## Known failure modes

- Missing required fields (total, start_ts, end_ts, now_ts) returns an error
- now_ts before start_ts may return zero vested tokens
- now_ts after end_ts may return full vesting (zero remaining)
- cliff_ts after now_ts returns zero vested tokens even if schedule has started
- Non-numeric or malformed timestamps cause validation errors
- Negative total token amounts may produce unexpected results

## How this service works

Remaining unlock amount for linear vesting with optional cliff. Call when token unlock schedules for runway/treasury math. Returns vested, remaining, fraction_vested as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object containing: the number of tokens vested so far, the number of tokens still remaining (unvested), and the fraction vested as a decimal — all computed for the requested evaluation timestamp based on the linear vesting schedule and optional cliff.
