## 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 gloom-market-bars-api-df3a1408
```

Example prompt: Pull the latest market bar data for AAPL and MSFT from Gloom — I need the price and volume for each.

## When to prefer this

Choose this endpoint when you need lightweight price and volume bar data for specific stock tickers, especially within an AI agent workflow that can handle per-call micropayments via x402. Prefer this over heavyweight financial data providers when you need a simple, cost-effective GET call for equity market bars without complex authentication setup.

## Known failure modes

- Missing required 'symbols' query parameter returns an error
- Invalid or unrecognized ticker symbol may return empty data array
- Payment failure (insufficient USDC balance) blocks the request under x402 protocol
- Rate limiting if too many symbols are requested at once
- Network timeout for very broad symbol queries

## 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 array of market bar objects, each containing the symbol, date, price, volume, a derived flag, and publishedAt timestamp. Example: {"data":[{"date":"2026-09-14","symbol":"AAPL","values":{"price":105.82,"volume":2069454},"derived":false,"observedAt":null,"publishedAt":"2026-09-14"}]}
