Endpoint
GEThttps://api.gloom.sh/v1/options/chains?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured options chain data — strikes, premiums, volume, and open interest — for one or more tickers filtered by a specific expiry date. It is well-suited for algorithmic trading research, options strategy analysis, and derivatives monitoring workflows. Prefer this over general stock quote endpoints when options-specific fields (contract symbol, open interest, side) are required.
Side effects
- Missing required 'symbols' or 'expiry' query params returns a 400 error
- Invalid or unrecognized ticker symbol may return empty data array
- Expiry date not matching any listed contracts returns empty results
- Payment not included or insufficient (x402 protocol) results in 402 Payment Required
- Rate limiting or upstream data provider outage may cause 5xx errors
- Malformed expiry date format may cause a parsing error or empty response
