# Full Market Snapshot

> Full Market Snapshot is a paid API for AI agents from agent.massive.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns the most up-to-date market data snapshot for all traded US stock symbols, optionally filtered by specific tickers.

## 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 full-market-snapshot-ab04776d
```

Example prompt: Pull the current market snapshot for AAPL, TSLA, and GOOG — I want to see the latest prices and trading data for all three right now.

## When to prefer this

Choose this endpoint when you need a broad, up-to-date snapshot of current market prices across many or all US equities in a single call rather than querying individual tickers one at a time. It is ideal for portfolio monitoring, market scanners, and dashboards that need live price data across the full US stock universe. Prefer this over daily summary endpoints when intraday real-time data is needed, and over moving average endpoints when raw price/volume snapshot data is the goal.

## Known failure modes

- Ticker symbols not found if passed in wrong case (case-sensitive input required)
- Snapshot data may be empty or stale before 4am EST when daily data has not yet populated
- OTC securities absent from response if include_otc not set to true
- Payment failure if USDC funds insufficient for the $0.01 per call fee
- Rate limits or API errors if too many simultaneous requests are made

## How this service works

Get the most up-to-date market data for all traded stock symbols. Note: Snapshot data is cleared at 3:30am EST and gets populated as data is received from the exchanges. This can happen as early as 4am EST. Can't find what you're looking for? POST feedback to /feedback, no charge.

## Output

Returns a market snapshot object for each requested ticker (or all traded US stock symbols if none specified), including current bid, ask, last trade price, today's open/high/low/close, volume, and percentage change. Data is sourced from US exchanges and refreshed continuously from approximately 4am EST after being cleared at 3:30am EST each trading day. OTC securities are excluded by default unless requested.
