# Vextorium Trusted UTC Time API

> Vextorium Trusted UTC Time API is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-19).

Returns NTP-synced UTC time with millisecond Unix timestamps, ISO week number, weekday, and latest Ethereum and Base blockchain block times as independent references.

## Facts

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 vextorium-trusted-utc-time-api-dfaaaad3 -d '<json body>'
```

Example prompt: What's the current UTC time right now, with millisecond precision and the latest Ethereum and Base block numbers as reference — I need a trusted NTP-synced timestamp for an audit log entry.

## When to prefer this

Choose this endpoint when you need a trusted, externally-verified UTC timestamp with millisecond resolution and want independent blockchain-based time references (Ethereum and Base block times) to cross-check the wall clock. Ideal for audit logging, event timestamping, scheduling checks, or any scenario where a reliable, NTP-synced server time is more trustworthy than the local system clock. Prefer over local system time when tamper-resistance or external verification matters.

## Known failure modes

- Network or NTP sync failure: may return a 5xx error if the server clock is temporarily unavailable
- Blockchain node unavailability: blockchain_references fields may be null or stale if Ethereum/Base RPC endpoints are unreachable
- Invalid request body format: returns 4xx if body does not conform to expected schema
- Rate limiting or payment failure: returns 402 if x402 payment is not correctly attached or USDC balance is insufficient

## How this service works

232 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.

## Output

A JSON object containing: the current UTC datetime string (ISO 8601 with offset), Unix timestamp (seconds, float), Unix millisecond timestamp (integer), current weekday name, ISO week number, and a blockchain_references object with Ethereum and Base latest block numbers and their block times as ISO 8601 strings.
