## How to call it through Zero

```sh
zero fetch --capability gloom-market-tape-api-c02192ec
```

Example prompt: Pull the live market tape for AAPL, TSLA, and NVDA from Gloom right now so I can see the latest trade activity for those three stocks.

## When to prefer this

Choose this endpoint when you need real-time market tape data (trades/quotes) for one or more financial symbols and want a low-cost, open-source-backed API with x402 micropayment support. Prefer this over traditional market data APIs if you are building an autonomous agent that handles per-call micropayments via USDC on the x402 protocol, or if you are already integrated with the Gloom finance terminal ecosystem.

## Known failure modes

- Missing or empty `symbols` query parameter returns an error or empty data array
- Invalid or unrecognized ticker symbols may return empty data arrays with no error
- Payment not completed (x402 protocol) results in a 402 Payment Required response
- Rate limiting or quota exceeded may block requests
- Network timeout if upstream market data feed is delayed

## How this service works

Gloom is a free, open-source finance terminal for desktop and TUI with charts, news, filings, portfolios, alerts, and plugins.

## Output

Returns a JSON object with a `data` array containing market tape entries for the requested symbols, including trade and quote records with price, volume, and timing information for each symbol provided.
