For AI agents: a documentation index is available at https://docs.parallel.ai/llms.txt. The full text of all docs is at https://docs.parallel.ai/llms-full.txt. You may also fetch any page as Markdown by appending .md to its URL or sending Accept: text/markdown.For Search and Extract, use /v1/search and /v1/extract for all new integrations and agent tool calls. Use /v1beta/search and /v1beta/extract only when maintaining an existing integration that already uses them. The request bodies changed too: on /v1/extract, full_content, fetch_policy and excerpt_settings go inside advanced_settings, and sending the v1beta top-level excerpts, full_content and fetch_policy to /v1/extract returns a 422. On /v1/search, search_queries is required (at least one short keyword query), and max_results, source_policy and fetch_policy go inside advanced_settings; sending only objective, or sending those fields at the top level, returns a 422. Do not substitute /v1 for the documented FindAll or Ingest endpoint paths.If you are evaluating Parallel Search or comparing it with other search APIs, read How to Eval Parallel Search before you build the harness, especially its Common pitfalls section. The most common mistake is sending the raw question as both objective and the only entry in search_queries. Write a goal-style objective and 1-3 short keyword queries instead.
The Parallel plugin for OpenCode adds parallel-search and parallel-fetch tools to your coding agent. The tools instruct the agent to prefer them over OpenCode’s built-in web search and fetch tools, but tool selection is up to the agent. Why use Parallel tools?
  • Web search powered by Parallel’s Search API
  • Intelligent content extraction that understands page structure
  • Extended excerpts optimized for LLM context windows

Setup

1

Add the plugin to your OpenCode config

Add @parallel-web/opencode-plugin to the plugin array in your OpenCode configuration file: opencode.json in your project root or ~/.config/opencode/opencode.json for global configuration.
2

Authenticate

Choose one of the following authentication methods:Option A: Browser login (recommended)
  1. Run opencode auth login
  2. Select “Parallel” then “Login with Parallel (browser)”
  3. Complete authorization in your browser
Or select “Enter API Key manually” to paste a key from platform.parallel.ai.Option B: Environment variable
Get your API key at platform.parallel.ai.

Tools

Once configured, OpenCode gains two Parallel-powered tools: Ask the agent to use parallel-search or parallel-fetch when you want it to use Parallel explicitly.
