Coverage means the provider returned a non-empty label for the probed address, it says nothing about label quality or correctness. Read the EOA vs contract split before concluding: a provider can look strong overall while only labeling contracts (verified-source names) and missing every wallet. The Success column is fetch reliability (share of API calls that did not error), not labeling accuracy.

How this pair was selected

Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
