SERP API pricing: compare the cost of the result, not just the plan
Current evidence boundary: our same-workload production cost benchmark is not complete. We therefore do not publish a cheapest-provider claim.
What a useful price comparison needs
For a fixed SERP workload, the useful denominator is the observable cost of successful comparable output. Plan price, API credits, request units, returned depth, failed calls and missing data can all affect that result.

Documented SERP API capability is verified, but SDB-B01 live request cost and completeness remain not tested.
SE Ranking API
In the prior frozen execution, the broader API run had a direct monetary cost of $0 under the available account and an observed unit delta of 1,020. That figure covers more than SERP tasks and is not presented as SERP cost per query.

Current API documentation is verified, but authenticated SDB entitlement and comparable production cost remain unresolved.
