# ManyLives Track Records Timing

> ManyLives Track Records Timing is a paid API for AI agents from manylives.me, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Returns onchain timing proof for a specific market data book period, showing when the Merkle root was committed to the blockchain relative to the period start.

## 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 manylives-track-records-timing-c0354cc1
```

Example prompt: Can you pull the onchain timing record for the CRY-5m book for the latest period — I want to see the transaction hash and how many seconds before the period start the Merkle root was committed?

## When to prefer this

Use this endpoint when you need to cryptographically audit or verify that a ManyLives market data book period was committed to the blockchain before the period started — specifically to obtain the transaction hash, block time, and seconds_before_start for provenance and integrity checks. Prefer this over generic block explorers when you want structured, book-specific timing metadata already correlated to the period.

## Known failure modes

- Unknown or invalid book ID returns an error or empty result
- Requested period label does not exist for the given book
- Network or service unavailability causes a timeout
- Payment not fulfilled causes a 402 response blocking the request
- Malformed query parameters result in a 400 error

## How this service works

No forms, no dropdowns. Describe the outcome in plain words and the Brain asks what it must, lists the job, collects offers and recommends one.

## Output

A JSON object containing the blockchain transaction hash (tx), book ID, period label, period start timestamp (UTC), a boolean indicating whether the Merkle root was included in calldata, the actual block time the transaction was mined onchain, and the number of seconds the commitment preceded the period start.
