Share an estimate, badge, or documented stack.
Each loop stays evidence-gated. APIDir will not mint a cheapest claim, embed unverified prices, or publish a stack without review.
Share a workload estimate
Turn clips and duration into a source-linked monthly estimate you can copy. The result never implies a cheapest provider.
Open the calculator →BadgeEmbed a cookie-free evidence badge
Link readers to a current first-party evidence profile. Historical pairs fall back to a neutral catalog badge.

Every number keeps its source.
APIDir preserves offer identity instead of collapsing unlike configurations into a single headline. Material changes are quarantined until reviewed. Old observations remain visible as historical evidence but cannot drive a current recommendation.
Use provider profiles to shortlist a route, verified rankings to inspect truly comparable meters, and the calculator to translate billing units into a workload estimate. Then open each first-party source before committing spend.
Questions developers ask
What does APIDir verify?
Every accepted observation records a provider route, model, billing unit, configuration, source URL, evidence hash, and check date.
Does APIDir name the cheapest provider?
Only when exact comparable offers are fresh. Stale or mismatched evidence cannot support a cheapest or savings claim.
Can providers pay for a better rank?
No. Future sponsorship will be clearly labelled and will never affect editorial ordering, evidence status, or price sorting.
Are documented integrations production-stack claims?
No. They describe what public source or first-party documentation shows and state the evidence boundary on every page.
