Parallel offers a Task and Deep Research API that returns deep web research and structured enrichments, with citations, reasoning, excerpts and confidence scores depending on tier. Nine processor tiers run from Lite at $5 per 1k requests to Ultra8x at $2,400, and the free allowance covers up to 5,000 requests a month.
