Search data API buyer's guide
The right API depends on the workload. Search Data Bench separates capability, observed execution and unresolved evidence instead of collapsing everything into one score.
1. Start with the workload
Define search engine, country, language, device, depth, keyword set and output fields before comparing providers.
2. Separate documented capability from execution
Documentation can prove an endpoint exists. It cannot by itself prove completeness, latency, reliability or the cost of your workload.
3. Preserve missing data and limits
No-data responses, rate limits and exhausted allowances are part of the result.
