Add Equibles to Data Providers

[daniel3303]

What is this resource?

Equibles (https://equibles.com) serves US company fundamentals as reported in SEC filings (XBRL), the filing full text, earnings-call transcripts, 13F holdings and insider trades through a hosted MCP server and a REST API, so LLM agents and research code can pull source-linked company data.

Why does it fit this list?

• Section: Data Providers, next to EarningsCall and Eulerpool, matching the table format there.
• Free or open API: persistent free tier of 100 requests/day with a free key, no credit card, trial or sales call (https://equibles.com/pricing). Limits are stated in the row.
• Open-source core: https://github.com/daniel3303/Equibles (AGPL-3.0, 230+ stars, commits this week) scrapes, stores and serves the SEC, 13F, insider and macro data and can be self-hosted with Docker.
• Differentiation: one connection joins filing text and transcripts with XBRL fundamentals and ownership data, useful for agent and NLP workflows that need the source document behind a number.
