LI.FI API Integration

LI.FI aggregates bridges, DEXs, intent solvers, and DeFi protocols behind one API. This skill covers the full product surface:

Product	Base URL	What it does
Core API (swaps & bridges)	`https://li.quest/v1`	Quotes, routes, execution data, status tracking across 75+ chains
Composer (DeFi execution)	`https://li.quest/v1` (same `/quote` endpoint)	One-click swap/bridge + deposit/withdraw into vaults, lending, staking
Earn (yield data)	`https://earn.li.fi/v1`	Vault discovery, APY/TVL analytics, portfolio positions
Intents (solver marketplace)	`https://order.li.fi`	Intent-based orders filled by a competitive solver network

For AI agents, LI.FI also offers an MCP server (https://mcp.li.quest/mcp) and a CLI (@lifi/cli). LI.FI recommends agents and backends use the REST API directly rather than the SDK.

Authentication & Rate Limits

API key is optional — it only raises rate limits. Header: x-lifi-api-key (get one at the LI.FI Partner Portal).
