How this service works
S&P 500, Nasdaq-100, and Russell 2000 constituents and GICS sectors.
Output
Returns a JSON object containing the normalized index name, a data_date indicating freshness, the total constituent_count, and a constituents array of objects (each with ticker and GICS sector fields). Also includes action, source, payload, and degraded flags for operational status.
Example use cases
Screening S&P 500 sector exposure
“Give me all the current S&P 500 constituents along with their GICS sectors so I can see which sectors are most represented.”
Verifying index membership for a ticker
“Is AMD currently a constituent of the Nasdaq-100? Look it up and tell me its GICS sector if it is.”
Building a Russell 2000 universe for analysis
“Pull the complete Russell 2000 constituent list for me — I need all the tickers and the data date so I know how current it is.”

Endpoint
GEThttps://api.edifiedlab.com/v1/market/indices?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an authoritative, up-to-date list of index constituents for S&P 500, Nasdaq-100, or Russell 2000, especially when GICS sector classification is also needed. It supports alias-based index naming (ndx, rut, sp500, etc.) making it convenient for agents parsing user intent. Prefer this over manual scraping or static datasets when freshness and structured output matter. It is not suitable for SPX or other indices not in the supported enum.
Side effects
- Invalid or unsupported index alias returns an error — only the documented enum values are accepted (e.g. SPX is explicitly not valid)
- Missing required 'index' query parameter results in a validation error
- Unknown ticker passed with a valid index returns an empty or null constituent match
- Degraded mode may return stale or partial data indicated by the 'degraded: true' flag
- Payment failure via x402 protocol blocks access before data is returned
