# Base DeFi Yield Optimizer API
[](https://base-defi.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Base chain DeFi yields -- Aerodrome LP, Moonwell lending, top farms ranked by APY with TVL and risk. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) 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.):
```json
{
"mcpServers": {
"base-defi": {
"url": "https://base-defi.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
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`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `base_get_defi_opportunities` | GET | `/api/opportunities` | $0.008 | Get DeFi yield opportunities on Base chain |
| `base_get_defi_opportunities` | POST | `/api/opportunities` | $0.008 | Get 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**
| Name | Type | Required | Description |
|---|---|---|---|
| `protocol` | string | no | Filter 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:
```json
{"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.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `protocol` | string | no | Filter 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:
```json
{"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.
