SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Accessing institutional-grade market intelligence like short interest, borrow rates, fails-to-deliver, 13F ownership, and insider transactions requires navigating Fintel's API surface, authentication, and endpoint selection, which this Skill handles for you. ## Core Features & Use Cases - Short Data & Squeeze Metrics: Retrieve short interest, days to cover, borrow rates, shares available to borrow, daily short volume, and SEC fails-to-deliver records. - Ownership & Insider Intelligence: Query 13F institutional holders and SEC Form 3/4/5 insider transactions, plus analyst price targets, ratings, and forecasts. - Use Case: Ask whether a stock is a short squeeze candidate, and the Skill pulls its short interest, borrow fee trend, and shares available to borrow from Fintel, presenting the data with context like percent of float and days to cover. ## Quick Start Ask the agent to show the current short interest and borrow rate for GME using Fintel.

Frequently Asked Questions about fintel-data

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I get short interest data for a stock via API?▼

Call the Fintel endpoint /v1/securities/{country}/{symbol}/short-interest with your X-API-KEY header to get trailing-year NYSE/NASDAQ-reported short interest. Note this dataset must be enabled per account, and the API returns 403 if you are not entitled.

How to check borrow rate and shares available to borrow?▼

Use the /v1/securities/{country}/{symbol}/borrow-rate endpoint, which returns the latest securities-lending fee rate, rebate rate, and shares available to borrow. High borrow fees combined with falling shares available indicate tightening borrow conditions.

Does the Fintel skill work on Claude.ai?▼

No, the skill is CLI only and requires shell access for curl, such as Claude Code or similar agents. It does not work on Claude.ai's sandbox, and the MCP alternative also requires a client that supports remote MCP servers.

Fintel API returns 403 for short interest data, why?▼

A 403 means the dataset is not enabled for your account. Short interest has limited availability and must be enabled per account on your Fintel API plan, even with a valid API key.

Can the Fintel skill create watchlists or alerts?▼

No, the skill is strictly read-only and only calls GET endpoints. Although the Fintel API exposes write operations for stock lists, alert subscriptions, and teams, the skill never invokes them per its read-only policy.

How do I look up a stock by CUSIP or ISIN in Fintel?▼

Use the /v1/identifiers/{type}/{value} endpoint with type set to cusip, isin, ticker, or id to resolve an external identifier to a security profile. You can also search by name or ticker via /v1/securities?query=...
