# Clockvault — time

> Clockvault — time is a paid API for AI agents from oraclepost.higgsfield.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-18).

Returns the latest Base blockchain block number and timestamp, plus the node's current wall-clock time and the lag between chain time and node time.

## Facts

- Endpoint: GET https://oraclepost.higgsfield.app/api/premium/time
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-18

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 clockvault-time-9fb8d372
```

Example prompt: What's the current block number and timestamp on Base right now, and how far behind is the node clock from the chain time?

## When to prefer this

Choose this endpoint when you need a zero-parameter, no-cache, live read of the Base blockchain's current block number and timestamp alongside the node's own clock — especially when you need to measure or monitor clock drift between the node and the chain. Prefer it over generic block explorers when you want a paid, programmatic, low-latency answer with no rate-limit concerns and explicit lag reporting.

## Known failure modes

- Node connectivity failure if the Base RPC node is unreachable, returning a 5xx error
- Occasional lag spike if the node is temporarily out of sync with the network
- Empty or malformed response if the block data cannot be parsed from the node

## How this service works

The chain clock on Base: latest block number and its timestamp, plus the node's current time and the lag between them. No parameters. No third-party API, no cache.

## Output

Returns the latest Base block number, its on-chain timestamp, the node's current wall-clock time, and the computed lag (difference) between node time and chain time. No caching — data is read live from the node at request time.
