How this service works
Gloom is a free, open-source finance terminal for desktop and TUI with charts, news, filings, portfolios, alerts, and plugins.
Output
Returns a JSON object with a data array containing crowding metrics for holdings — likely including asset identifiers, crowding scores or rankings, and concentration statistics indicating how widely or heavily various positions are held across investors or funds.
Example use cases
Identify crowded hedge fund trades
“Pull the latest crowding data from Gloom and show me which equities are most crowded among institutional holders — I want to avoid piling into positions that are already over-owned.”
Risk screen before portfolio rebalance
“Before I rebalance, check Gloom's holdings crowding endpoint to flag any of my current positions that show high crowding risk from institutional concentration.”
Spot contrarian opportunities
“Use Gloom to find the least crowded holdings right now — I'm looking for under-owned positions that institutional money hasn't piled into yet.”
Technical details
Endpoint
GEThttps://api.gloom.sh/v1/holdings/crowding?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quantitative crowding or concentration signals for holdings — particularly useful before entering or exiting a position to assess how over-owned it is. Prefer this over generic market data APIs when the specific question is about positional crowding, overlap, or institutional concentration rather than price, volume, or fundamentals.
Side effects
- Empty data array returned if no holdings match the filter criteria
- Invalid or malformed properties parameter returns a 400 error
- Payment required (HTTP 402) if USDC payment header is missing or insufficient
- Stale data if upstream institutional filing data has not been refreshed
- Rate limiting if too many requests are made in quick succession
