What belongs on this financial data APIs page?
This page is for API-first financial data products with endpoints, documentation, SDKs, quotas, rate limits, exports, licensing, or data delivery workflows for developers and data teams.
How is this different from stock analysis software?
Stock analysis software is investor-facing. Financial data APIs are developer-facing or data-team-facing products used to build apps, models, dashboards, databases, and internal research systems.
Are filing and transcript APIs included?
Yes, when API access is a primary workflow. Interactive filing search and transcript research products still fit better on their dedicated SEC filing or earnings call transcript pages.

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
