Utilities
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 service-level health information for every Market Data endpoint. No authentication token is required — status() is reachable in demo mode and is the SDK's own probe before retrying a 5xx response.
📄️ Headers
Echo back the request headers your client actually sent to Market Data. Useful for debugging proxies, custom header plumbing, or verifying the User-Agent the SDK is presenting.
