DefiLlamaInstall

Overview

The node integrates with the DefiLlama API to retrieve data about cross-chain bridges in the decentralized finance (DeFi) ecosystem. Specifically, the "List Bridges" operation fetches a list of all cross-chain bridges along with their volume data over selectable time ranges.

This node is useful for users who want to monitor or analyze cross-chain bridge activity, such as tracking transaction volumes, understanding liquidity flows between blockchains, or comparing bridge usage trends.

Practical examples:

• A DeFi analyst can use this node to get the latest volume statistics of popular bridges over the past 24 hours or 7 days.
• A developer building a dashboard can list bridges and display their recent volume changes and supported chains.
• Portfolio managers can filter bridges by minimum volume thresholds to focus on significant liquidity providers.

Properties

Output

The node outputs an array of JSON objects representing bridges. Each bridge object includes:

• Basic bridge information such as name and supported chains.
• Volume data corresponding to the selected date range (e.g., volumePrevDay for 24h).
• Calculated fields like volumeChange showing percentage change compared to the previous period.
• Formatted fields for easier reading, e.g., volumePrevDay_formatted showing volume in human-readable currency format.
• Metadata including resource type ("bridges"), operation ("listBridges"), and timestamp of data retrieval.

If AI Agent Mode is enabled, the output is a single JSON object containing:

• ai_summary: a concise human-readable summary of the top bridges.
• total_results: total number of bridges returned.
• data: the full array of bridge data.
• resource, operation, and timestamp fields.

No binary data is produced by this node.

Dependencies

• Requires internet access to call the DefiLlama public API endpoints at https://bridges.llama.fi/.
• Optionally supports using an API key credential if provided, which will be sent as a Bearer token in the Authorization header.
• No other external dependencies are required.

Troubleshooting

• Empty or no data returned:
  Check that the API endpoint is reachable and that the DefiLlama service is operational. Also verify that any filters (e.g., minVolume) are not too restrictive.

• Invalid parameter errors:
  Ensure that numeric inputs like Max Results and Min Volume are within allowed ranges. For example, Max Results must be between 1 and 100.

• API rate limits or authorization errors:
  If using an API key, confirm it is valid and has sufficient permissions. Without a key, the node uses public endpoints which may have stricter rate limits.

• Unexpected response structure:
  The node expects certain fields from the API; if the API changes, the node might fail or produce incomplete data. Check for updates to the node or API documentation.
