# World Stock Exchanges Clock

> World Stock Exchanges Clock is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Returns the current open/closed status, local time, today's session hours, and next open time for up to 12 major global stock exchanges.

## Facts

- Endpoint: POST https://api.vextorium.com/horario-bolsas-pago?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402

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 world-stock-exchanges-clock-1eac15f9 -d '<json body>'
```

Example prompt: Are NYSE, London, and Tokyo stock exchanges currently open? Also tell me the local time at each and when the next session starts for any that are closed.

## When to prefer this

Choose this endpoint when you need status information for multiple global exchanges simultaneously (outside US markets). Use the sibling US-only endpoint for a cheaper, faster NYSE/Nasdaq-only check. Prefer this when your agent needs to coordinate trading logic across international time zones, check for holidays, or determine the next open session for non-US markets like Tokyo, Hong Kong, Shanghai, or Mumbai.

## Known failure modes

- Invalid exchange code in bolsas array returns validation error
- Malformed ISO 8601 datetime in fecha_hora causes parse error
- Payment failure or insufficient USDC balance blocks the request
- If no exchanges are specified, defaults to all 12 — unexpectedly large response

## How this service works

World stock exchanges clock: status (open, closed, lunch break), local time, today's session and next open for NYSE, Toronto, London, Euronext, Xetra, Madrid, Zurich, Tokyo, Hong Kong, Shanghai, India and Sydney.

## Output

Returns an array of exchange objects each containing: exchange name, code, status (open/closed/lunch break), local time, today's session in UTC, next open time in UTC, closure reason if applicable, and holiday data. Also includes a top-level UTC timestamp of the query moment and a list of currently open exchange codes.
