## 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-world-stock-exchanges-market-hours-42410b75 -d '<json body>'
```

Example prompt: Which of the major stock exchanges are open right now — specifically NYSE, London, Tokyo, and Hong Kong — and when does the next session start for any that are closed?

## When to prefer this

Use this endpoint when you need real-time or point-in-time open/closed status for major global stock exchanges, especially when covering multiple exchanges at once. It is purpose-built for trading workflow automation, pre-trade checks, and scheduling tasks around market hours. Prefer it over generic financial data APIs when you need local times, next-open timestamps, and lunch-break awareness across NYSE, London, Tokyo, and other major markets simultaneously.

## Known failure modes

- Invalid exchange code returns an error or is silently ignored
- Malformed ISO 8601 datetime causes a validation error
- Network timeout if the service is unavailable
- Response may not reflect intraday halts or emergency closures not in the schedule
- Holiday data may lag for newly announced market closures

## 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.
