Documentation Overview
DeFi Yield Finder API
Best DeFi yields ranked by APY -- lending, staking, LP across 100+ protocols. Powered by DeFiLlama. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
Quickstart -- HTTP (x402)
Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.
Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
defi_find_best_yields | GET | /api/yields | $0.005 | Find best DeFi yield opportunities for a token |
defi_find_best_yields | POST | /api/yields | $0.005 | Find best DeFi yield opportunities for a token (POST variant) |
defi_find_best_yields
Use this when you need to find the best DeFi yields for a token across all chains and protocols. Returns ranked opportunities in JSON.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
token | string | yes | Token symbol to find yields for (e.g. USDC, ETH, WBTC) |
chain | string | no | Filter by chain (e.g. base, ethereum, arbitrum, polygon). Optional — returns all chains if omitted. |
minTvl | number | no | Minimum TVL in USD to filter pools (default: 100000) |
limit | number | no | Number of results to return (default: 10, max: 50) |
Returns
pool-- pool/vault name and pairprotocol-- protocol name (Aave, Compound, Lido, Aerodrome, etc.)chain-- which blockchain networkapy-- current annual percentage yieldtvl-- total value locked in USDriskLevel-- risk assessment (low/medium/high)type-- yield type (lending, staking, LP, vault)
Example response:
When to use: deploying idle capital to find the highest safe yield. Essential for yield optimization and DeFi strategy comparison.
Not for: swap quotes (use dex_get_swap_quote), wallet balance (use wallet_get_portfolio), liquidation risk (use defi_get_liquidation_levels).
defi_find_best_yields
Use this when you need to find the best DeFi yields for a token across all chains and protocols. Returns ranked opportunities in JSON. POST variant of defi_find_best_yields -- same params passed as JSON body instead of query string.
