Code agents need fast, structured web data to ground their outputs in reality. Whether you are building with Claude Code, Cursor, or a custom Pi agent, the search API you plug in determines how accurate and current your agent responses are. We tested five APIs head-to-head on latency, JSON structure quality, and per-query cost for agentic coding workflows.
Scavio wins for code agents because it returns pre-structured JSON with no parsing overhead, costs $0.005/credit, and handles SERP + People Also Ask + related searches in a single call that agents can consume without transformation.
