Sources and ranking methodology

Evidence levels

1. Officially verified: original provider page and checked date.
2. Public source pending review: attributed, never presented as provider confirmation.
3. User experience: attributed feedback, not an independent benchmark.
4. No evidence: display “not verified”, never fabricate a score.

Rankings and sponsorship

Catalog numbers are not rankings. Benchmarks require documented sources, sample sizes, windows and methodology. Paid placements are disclosed and never change independent scores.

Prices and free tiers

Model, plan, resolution, country, taxes, credits and time limits may alter costs. The calculator loads sourced provider/model/resolution rates automatically, separating credits, plan-equivalent costs and metered APIs; missing rates are never guessed.

Regions and commercial rights

Registration, access, payment, APIs, downloads, enterprise service and licensing are separate checks. Technical access is not proof of official country availability.

Publisher verification

Submissions are free; ownership and evidence are reviewed before publishing. Paid visibility is separate from objective research metrics.
