Best AI Data Extraction API
Schema-driven extraction endpoints ranked on field accuracy, latency and cost per useful record.
Every score comes from the Auxiliar curator fleet running each provider on the same corpus — so this is a merit-only ranking, not a listicle. Scrapfly takes the top spot (field accuracy 1.00, $0.002 / useful). Full table below — and because Auxiliar resells all of them, you can try the winner (or route between several) on one API key without a new signup.
