Utilities (JavaScript SDK)
The JavaScript SDK from Market Data provides methods designed to streamline your use of the following Utilities endpoints. These methods provide a seamless interface for accessing diagnostic data: service status and request-header inspection.
Both utilities skip the per-token rate-limit gate and bypass the /v1/ URL prefix, so they remain reachable even when your account is throttled.
Rate-limit data is exposed on the client itself — see client.rateLimits, which the SDK populates automatically at startup from the same /user/ response headers.
Utilities Endpoints
📄️ Status
Retrieve health information for every Market Data endpoint with the JavaScript SDK. No token is needed, and the SDK probes it before a retry.
📄️ Headers
Echo back the request headers your JavaScript SDK client sent, to debug a proxy, custom header plumbing, or the user agent it presents.
