# Chainlink Documentation > Navigation index for Chainlink developer documentation. Use this file to locate the most relevant page for a task. Prefer `.md` pages. Retrieve the smallest relevant page first. If a `.md` page is incomplete or missing key content, use the corresponding HTML page. Do not rely on memorized addresses, supported networks, billing details, or service limits. For multi-step tasks, retrieve and combine multiple specific pages rather than relying on a single overview page. Use product documentation indexes for deeper product-specific navigation. Use `llms-full.txt` only for conceptual understanding or documentation context. Do not use `llms-full.txt` to retrieve structured data such as: - feed addresses - stream IDs - network metadata Structured data must be retrieved from dataset endpoints. --- ## Live Data and Structured Datasets You must use structured datasets when retrieving current network data, addresses, or routing information. Do not scrape documentation pages or interactive tables for structured data. When retrieving structured data, always prefer dataset endpoints over documentation pages. ### Data Feeds - Index (select network): https://docs.chain.link/data-feeds/feed-addresses/default.txt https://docs.chain.link/data-feeds/feed-addresses/default.json - Per-network datasets: https://docs.chain.link/data-feeds/feed-addresses/{type}/{network}.txt https://docs.chain.link/data-feeds/feed-addresses/{type}/{network}.json - Example: https://docs.chain.link/data-feeds/feed-addresses/default/ethereum-mainnet.json ### Data Streams - Stream ID datasets: https://docs.chain.link/data-streams/stream-ids/crypto.txt https://docs.chain.link/data-streams/stream-ids/crypto.json - Network metadata (verifier proxies): https://docs.chain.link/data-streams/networks.txt https://docs.chain.link/data-streams/networks.json Note: Network metadata (including verifier proxy addresses) is included in each stream ID dataset (`.json`) and should be used directly. Fetch the networks dataset only if additional network context is required. - Examples: https://docs.chain.link/data-streams/stream-ids/crypto.json https://docs.chain.link/data-streams/networks.json Network metadata is included in the stream dataset; the networks endpoint is optional. ### CCIP Directory - CCIP Mainnet Directory: https://docs.chain.link/ccip/directory/mainnet - CCIP Testnet Directory: https://docs.chain.link/ccip/directory/testnet --- Note: - JSON datasets (`.json`) provide structured, programmatically consumable output and should be preferred when available. - Stream ID JSON datasets include associated network metadata and should be treated as complete, single-step retrieval sources. - Static `.txt` datasets are available for bulk retrieval and indexing. --- ## Core Documentation - [Conceptual Overview](https://docs.chain.link/getting-started/conceptual-overview.md) - [Oracle Platform Overview](https://docs.chain.link/oracle-platform/overview.md) - [LINK Token Contracts](https://docs.chain.link/resources/link-token-contracts.md): Use when funding contracts or configuring Chainlink services.

For full coverage: - Use product documentation indexes for structured navigation - Use full documentation bundles when broad context is required --- ## Product Documentation Indexes Use these for deeper product-level navigation.
