PUBLIC DATA / API ACCESS
Public data APIs
Find published records you can query, download and build with. Each source has its own access rules and reuse conditions (an open endpoint does not settle ownership or licensing).
Explore the sources
Polymarket↗
Polymarket publishes market metadata, outcome prices and order-book data through public read interfaces. Query filters and rate limits vary by endpoint; authenticated trading and Polymarket US are separate services.
Read API access, limits and sourcesSEC EDGAR↗
SEC EDGAR provides company submissions and extracted XBRL facts as public JSON, plus nightly bulk archives. Automated clients must identify themselves and follow the SEC’s fair-access limits.

Public filings and market records usually describe information published by issuers, a platform or other participants. This directory examines usable access, refresh behavior and permission to reuse those records. Authenticated filing submission, trading and private account data require separate assessments.
These sources carry no customer-control grade. Our software directory asks how much control customers retain over the systems holding their own business records; cancellation and native workflow migration do not describe these public feeds.
