What it does
Query Fintel (fintel.io) institutional market data through its REST API or official MCP server. Use this skill whenever the user mentions Fintel or asks about short interest, short interest ratio or days to cover, short squeeze data, borrow rate or cost to borrow, shares available to borrow, daily short volume, fails-to-deliver (FTD), 13F institutional owners ("who owns X"), insider buying or selling from SEC Form 3/4/5, analyst price targets, ratings and forecasts, dividend or earnings history and calendars, EOD or last prices, security lookup by ticker, CUSIP, ISIN, or FIGI, Fintel leaderboards, or their Fintel watchlists and alerts. Read-only: GET endpoints only.
Fintel Data Skill
If your host has not already executed the shell probes below (for example, in Codex), run the commands inside the ! wrappers with its shell tool before choosing a setup path. Use the actual output; if shell access is unavailable, report that limitation.
Fintel (fintel.io) is an institutional-grade market intelligence platform. Its strongest datasets are the ones most other providers lack: short interest, borrow rates, short volume, fails-to-deliver, 13F institutional ownership, and insider transactions.
Fintel exposes two surfaces backed by the same data contract:
| Surface | Endpoint | Auth | Best for |
|---|---|---|---|
| REST | https://api.fintel.io/v1/* | X-API-KEY header | Default, curl from any CLI agent |
| MCP | https://mcp.fintel.io/mcp | X-API-KEY header | MCP-native clients, tool auto-discovery |
Both require a Fintel API key. This skill is read-only, only call GET endpoints. The API also exposes write endpoints (create/delete stock lists, alert subscriptions, teams); do not call them.
Step 1: Resolve FINTEL_API_KEY
The skill resolves FINTEL_API_KEY in this order:
FINTEL_API_KEYenvironment variableFINTEL_API_KEYin.envin the current directoryFINTEL_API_KEYin.envat the git repo root (so a worktree inherits the key from the main checkout)
!`if [ -n "$FINTEL_API_KEY" ]; then echo "KEY_FROM_ENV_VAR"; elif [ -f .env ] && grep -qE "^FINTEL_API_KEY=" .env; then echo "KEY_FROM_LOCAL_DOTENV:$(pwd)/.env"; else GIT_COMMON=$(git rev-parse --path-format=absolute --git-common-dir 2>/dev/null); if [ -n "$GIT_COMMON" ]; then ROOT=$(dirname "$GIT_COMMON"); if [ -f "$ROOT/.env" ] && grep -qE "^FINTEL_API_KEY=" "$ROOT/.env"; then echo "KEY_FROM_ROOT_DOTENV:$ROOT/.env"; else echo "KEY_NOT_SET"; fi; else echo "KEY_NOT_SET"; fi; fi`
Then act on the result:
