Parallel

Parallel Web Systems builds web APIs purpose-built for AI agents: a high-accuracy Search API, an Extract API that turns URLs into clean LLM-ready markdown, a Task/Deep Research API with tiered processors (lite through ultra), FindAll for natural-language entity discovery and enrichment, a Monitor API for scheduled web-change tracking, and an OpenAI-compatible Chat Completions endpoint. The platform is API-key authenticated over https://api.parallel.ai, ships official Python and TypeScript SDKs and a CLI, exposes free and authenticated MCP servers, emits Standard Webhooks and SSE event streams, and is SOC 2 Type I/II certified. Originally surfaced as a Kleiner Perkins portfolio company and enriched from Parallel's public developer surface.

Parallel publishes 1 API on the APIs.io network. Tagged areas include Company, Ai, Web Search, Agents, and Deep Research.

The Parallel catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Parallel’s developer surface includes documentation, API reference, getting-started guide, pricing, engineering blog, signup flow, support, and 28 more developer resources.
