Exa API for coding agents

View Agent Bench results API docs

Exa passed every retrieval attempt and was the quickest provider by median latency in each of our three cases. Its card-free Starter plan is the easiest clean launch path in this set, although publication-date metadata was less complete than Perplexity's.
