# Financial Context

> Authenticated market data endpoints served from openapi.fcontext.com

Financial Context provides authenticated, metered access to read-only US market data. Use supported paths under `/api/market-data/*` for quotes, candlesticks, company data, news, calendars, screeners, and related analytics.

## Base URL

```text theme={null}
https://openapi.fcontext.com
```

Every endpoint in this reference is rooted at `https://openapi.fcontext.com/api/market-data` and uses `.US` symbols or the `US` market where a symbol or market filter is required.

## Authentication

Use a Financial Context key from account settings:

```bash theme={null}
curl "https://openapi.fcontext.com/api/market-data/quote?symbols=AAPL.US" \
  -H "x-api-key: YOUR_FCONTEXT_API_KEY"
```

OAuth clients can use a bearer token with market-data access:

```bash theme={null}
curl "https://openapi.fcontext.com/api/market-data/quote?symbols=AAPL.US" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```

## Path Format

Use supported read-only `GET` endpoints after the `/api/market-data` prefix. For example, use `https://openapi.fcontext.com/api/market-data/quote` for realtime quotes, `https://openapi.fcontext.com/api/market-data/content/news` for news, and `https://openapi.fcontext.com/api/market-data/fundamental/company` for company overview data. The API reference lists the current endpoint surface.

Use query strings for filters, date ranges, pagination, and endpoint-specific options.

## Limits And Errors

All market-data requests are metered as Financial Context data requests.
