Base DeFi Yield Optimizer API

Base chain DeFi yields -- Aerodrome LP, Moonwell lending, top farms ranked by APY with TVL and risk. 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.):

{
  "mcpServers": {
    "base-defi": {
      "url": "https://base-defi.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl "https://base-defi.api.klymax402.com/api/opportunities"
# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

base_get_defi_opportunitiesPOST/api/opportunities$0.008Get DeFi yield opportunities on Base chain (POST variant)
base_get_defi_opportunities

Use this when you need DeFi yield opportunities specifically on Base chain. Returns Base-native protocol yields in JSON.

Parameters

NameTypeRequiredDescription
protocolstringnoFilter by protocol: 'all', 'aerodrome', or 'moonwell'. Defaults to 'all'.

Returns

  • opportunities -- array of yield farms ranked by APY
  • protocol -- protocol name (Aerodrome, Moonwell)
  • pool -- pool name and token pair
  • apy -- current annual percentage yield
  • tvl -- total value locked in USD
  • riskScore -- risk rating (1-10, lower is safer)
  • type -- yield type (LP, lending, staking)

Example response:

{"opportunities":[{"protocol":"Aerodrome","pool":"USDC/WETH","apy":18.5,"tvl":45000000,"riskScore":3,"type":"LP"},{"protocol":"Moonwell","pool":"USDC Lending","apy":5.2,"tvl":120000000,"riskScore":1,"type":"lending"}],"chain":"base","totalPools":12}

When to use: deploying capital on Base chain specifically. Curated list of vetted Base-native protocols only.

Not for: swap quotes on Base (use dex_get_swap_quote), liquidation risk (use defi_get_liquidation_levels).

base_get_defi_opportunities

Use this when you need DeFi yield opportunities specifically on Base chain. Returns Base-native protocol yields in JSON. POST variant of base_get_defi_opportunities -- same params passed as JSON body instead of query string.
