Agent skill fromhimself65/finance-skills
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.

1# Fintel Data Skill23If 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.45Fintel ([fintel.io](https://fintel.io)) is an institutional-grade market6intelligence platform.7Its strongest datasets are the ones most other providers lack: **short8interest, borrow rates, short volume, fails-to-deliver, 13F institutional9ownership, and insider transactions**.1011Fintel exposes two surfaces backed by the same data contract:1213| Surface | Endpoint | Auth | Best for |14|---|---|---|---|15| **REST** | `https://api.fintel.io/v1/*` | `X-API-KEY` header | Default — curl from any CLI agent |16| **MCP** | `https://mcp.fintel.io/mcp` | `X-API-KEY` header | MCP-native clients, tool auto-discovery |1718Both require a Fintel API key. **This skill is read-only** — only call19GET endpoints. The API also exposes write endpoints (create/delete stock20lists, alert subscriptions, teams); do not call them.2122---2324## Step 1: Resolve FINTEL_API_KEY2526The skill resolves `FINTEL_API_KEY` in this order:271. `FINTEL_API_KEY` environment variable282. `FINTEL_API_KEY` in `.env` in the current directory293. `FINTEL_API_KEY` in `.env` at the git repo root (so a worktree inherits the key from the main checkout)3031```32…
