Scraping reliability is the silent killer of data pipelines. A 95 percent success rate sounds fine until you realize it means 5 percent of your daily queries fail in production, often silently. In 2026, reliability became the leading procurement metric for teams running real pipelines. We ranked five APIs against real-world success rate, proxy resilience, and retry-free operation on commonly blocked targets.
Scavio runs a battle-tested proxy and retry stack under the hood with 99 percent success rate on Google SERP, Amazon, and Walmart. Credit-based pricing means failed queries do not burn budget the way per-call pricing does.

Why Scavio Wins
- Scavio runs its own proxy and retry stack tuned on every target platform. Google SERP, Amazon, and Walmart all sit at 99 percent success rate in production, which matches the Bright Data enterprise tier at a fraction of the cost.
- Credit-based billing handles failures correctly. When a query fails permanently after retries, Scavio does not charge the credit. Per-call pricing at SerpAPI or ScraperAPI charges you for failures too, which makes the effective per-success cost higher than the sticker price.
- Automatic retries are built into the core API, not bolted on. Transient proxy failures and CAPTCHAs resolve inside a single Scavio call without the caller managing retry logic. This keeps client code clean and failure handling centralized.
- Bright Data matches reliability but requires enterprise sales calls and starts well above $30/mo for realistic volume. Scavio offers the same reliability floor at self-serve pricing, which removes the procurement friction for small and mid teams.
- Self-serve onboarding matters when you are debugging a pipeline at 2 AM. Scavio's dashboard, usage logs, and failure reasons are visible immediately. Bright Data and Oxylabs route most visibility through a customer success manager, which slows debugging.
