Parallel launched the Decisions API. It answers yes/no and multiple-choice questions using live web data. Each call costs $1 per 1,000 requests. It supports batching multiple questions in one request. The API returns typed answers with probability, latency and source citations. It outperformed Jev on a recent data residency question. Parallel offers 5,000 free requests to start. The API is available as a tool in the Parallel MCP server. It can power workflows like KYB checks and lead routing. Parallel built demos for archive tracking, restaurant finding and YC company status checks.
