## 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 robinhood-chain-session-clock-d73d50f1 -d '<json body>'

Example prompt: What's the current session clock status on Robinhood Chain — is the tokenized stock market open right now, and how much time is left in the session?

## When to prefer this

Use this endpoint when an agent needs to gate trading logic or decisions on the current Robinhood Chain tokenized-stock session state — for example, avoiding trades outside market hours, timing entries around session transitions, or syncing bot logic with pre-market vs regular vs after-hours windows. It is specifically scoped to Robinhood Chain's tokenized equity session timing rather than generic crypto 24/7 markets.

## Known failure modes

- Network or Railway deployment downtime returning 5xx errors
- Payment failure if USDC/USDG balance is insufficient for the $0.003 per-call fee
- Malformed or unexpected POST body returning 400 validation error
- Session clock data temporarily stale if upstream Robinhood Chain feed is delayed

## How this service works

US equity market session clock: is the underlying cash market (NYSE/Nasdaq) open, pre-market, after-hours, or closed right now, with holiday/half-day awareness and minutes-to-open/close. Send {}. The scheduling primitive every 24/7 Robinhood Chain agent needs to time premium/discount and gap trades around market hours.

## Output

Returns the current session clock state for the Robinhood Chain tokenized-stock environment, likely including fields such as current session name (e.g. pre-market, regular, after-hours), session open/close timestamps, time remaining in the current session, and overall market open/closed status.
