How listings and guides are maintained
The goal is useful, traceable information rather than the largest possible page count. Pages that lack enough distinct source coverage are kept out of the search index until they provide meaningful value.
01
Research the original source
Listings start with the provider's website, documentation, public agency page, or another authoritative primary source.
02
Record only supported facts
We do not infer API availability, pricing, geographic coverage, update frequency, or product capabilities when the source does not state them.
03
Apply a consistent taxonomy
Each listing uses one primary category and specific, overlapping tags for format, property type, source type, data points, and professional use cases.
04
Link readers to verification
Listings provide the provider website and documentation links when available. Readers should confirm current commercial and technical details before relying on them.
05
Monitor and correct
Automated monitoring can identify provider changes, while correction reports help surface errors. AI-assisted summaries are treated as drafts and remain subject to verification.
Corrections
Each listing includes a reporting path for factual corrections. Material updates should be checked against the provider's current published information before the listing is changed.
