The shared forge

Raw truth in.
Stable contracts out.

Dataset modules never reinvent authentication, metering, errors, pagination, or version behavior. The shared gateway owns the developer contract while every record remains traceable to an immutable source snapshot.

Source before summary

AI may help normalize or explain a field, but it never becomes the factual authority.

Two version clocks

Each API has its own contract history. Each dataset release separately reports its source version and refresh date.

Safe promotion

Validated releases become active atomically. Prior releases remain available for rollback and reproducibility.

Coverage is data

Connectors expose what is included, what is missing, and when every source last succeeded.

Dataset ledger

The active API catalog.

All 35 implemented datasets live here with their sources, dependencies, cadence, risk, contract version, and current release state.
