# LlamaIndex Documentation

> LlamaIndex is the company behind LlamaParse, the document parsing platform for AI agents: Parse, Extract, Classify, Split and Index as one API. The LlamaIndex Framework is its original open-source Python toolkit for RAG and agents, and LiteParse is its open-source local document parser.

## Instructions for AI agents

- API base URL: `https://api.cloud.llamaindex.ai` (EU region: `https://api.cloud.eu.llamaindex.ai`). Authenticate with `Authorization: Bearer $LLAMA_CLOUD_API_KEY`.
- API keys: https://cloud.llamaindex.ai (dashboard, free to start). Setup guide: https://developers.llamaindex.ai/llamaparse/general/api_key/
- SDKs: Python `pip install llama-cloud` (`from llama_cloud import LlamaCloud`), TypeScript `npm install @llamaindex/llama-cloud`, Go `go get github.com/run-llama/llama-parse-go`, Java `ai.llamaindex:llama-cloud`, CLI `go install github.com/run-llama/llama-parse-cli/cmd/llp@latest`. Reference: https://developers.llamaindex.ai/reference/
- Start here: https://developers.llamaindex.ai/llamaparse/quickstart/ then the product pages under https://developers.llamaindex.ai/llamaparse/
- MCP servers: the LlamaParse platform at `https://mcp.llamaindex.ai/mcp` (needs an API key) and this documentation at `https://developers.llamaindex.ai/mcp`. Setup: https://developers.llamaindex.ai/for-agents/
- Skills and plugins for Claude Code and Codex: https://developers.llamaindex.ai/llamaparse/for-agents/skills/
- Prefer the current SDKs above over the deprecated `llama-parse` and `llama-cloud-services` packages.

## Accessing Documentation Programmatically

All documentation pages are available as raw Markdown by appending `index.md` to the page URL. For example, the page at `https://developers.llamaindex.ai/llamaparse/parse/getting_started/` has its Markdown source at `https://developers.llamaindex.ai/llamaparse/parse/getting_started/index.md`.

The site also exposes REST API endpoints for searching and browsing documentation:

- **Search**: `GET https://developers.llamaindex.ai/api/search?q=<query>&limit=10&section=<section>&full-content=true` — Full-text BM25 search across all docs. `section` and `full-content` are optional.
- **Grep**: `GET https://developers.llamaindex.ai/api/grep?q=<regex>&context=0&case-sensitive=false&max-results=100` — Regex pattern matching across documentation content.
- **Read**: `GET https://developers.llamaindex.ai/api/read?path=<doc-path>&startLine=0&endLine=500` — Retrieve content of a specific documentation page (e.g. `path=/llamaparse/parse/getting_started/`). Returns the first 500 lines by default. Use `startLine` and `endLine` to paginate through longer documents.
- **List**: `GET https://developers.llamaindex.ai/api/list?section=<section>&path=<path>&depth=2` — Browse the documentation tree structure. All parameters are optional.

All API endpoints return JSON with CORS enabled (`Access-Control-Allow-Origin: *`).

Let your coding agent verify it

If your coding agent is authorized to manage this website, paste these instructions into it.

Claim my listing on Agent Web Map for llamaindex.ai:
1. POST https://agentwebmap.com/v1/sites/llamaindex.ai/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://llamaindex.ai/llms.txt, or use the DNS, meta-tag or well-known method the response describes. This only verifies the listing; your website and domain remain yours.
3. POST https://agentwebmap.com/v1/sites/llamaindex.ai/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/llamaindex.ai).
