FROM CAPABILITY TO DECISION

Search is cheap.
Verification isn’t.

01 /

Describe the capability.

In any language. Add constraints: geography, auth, budget, free tier, commercial use, data residency.

02 /

We research the providers.

Targeted searches in the languages that matter, then official docs and pricing pages are retrieved and read.

03 /

Get evidence, not vibes.

Every price, endpoint and limit is a verbatim quote with URL and timestamp. Unknowns stay unknown; unsuitable APIs are rejected with a reason.

MACHINE-FIRST BY DESIGN
