Directory of metrics ingested for this asset — for populating chart dropdowns.

A thin wrapper over `/api/v1/on-chain/{asset}` summary mode that trades the latest VALUE for a minimal directory-style response. Clients use it to build 'what can I chart for this asset?' dropdowns without pulling every metric's current reading. Empty array is a valid 200 for assets we haven't ingested yet.

Path parameters

Segments of the URL path, validated server-side.

Query parameters

This endpoint takes no query parameters.

Response shape

Always wrapped in the standard envelope. Nullable fields are explicitly marked — treat missing numeric data as a real data-source gap, not as an error.

// Wrapped in the standard envelope:
// {
//   data: /* shape below */,
//   meta?: { total?: number; limit?: number; offset?: number; ... }
// }

{
  asset: string;
  metrics: Array<{ metricName: string; latestTs: number; source: string | null }>;
}

Example

Copy the curl, replace YOUR_KEY with a real key from your dashboard, and run.
