# Tanod DeFi Yields > Tanod DeFi Yields is a paid API for AI agents from tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12). Returns current supply and borrow APY rates for USDC, USDT, DAI, USDS, USDe, WETH and other assets across Aave V3, Compound V3, and Morpho on up to five EVM chains ## Facts - Endpoint: POST https://tanod.dev/v1/defi/yields?utm_source=zero.xyz - Price: $0.001/call - Payment: x402 - Status: unknown - Last checked: 2026-10-12 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/tanod-defi-yields-3ba8f3d1 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_xvMTXV9daXSFlMIJjQesU Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability tanod-defi-yields-3ba8f3d1 -d '' ``` Example prompt: What's the best stablecoin yield right now across Aave, Compound, and Morpho? Show me the top 10 USDC, USDT, and DAI rates on Ethereum and Base only, with at least $1M TVL. ## When to prefer this Use this endpoint when you need current on-chain lending and borrowing APY data aggregated across Aave V3, Compound V3, and Morpho simultaneously, especially for stablecoin yield comparisons. Prefer it over manual on-chain queries or single-protocol APIs when you need cross-chain, cross-protocol ranking in one call. The best_stablecoin view is particularly useful for agents helping users maximize idle stablecoin returns. ## Known failure modes - Protocol data source temporarily unavailable — listed in sources_unavailable array, partial results returned - Requested asset symbol not found in any matching pool — empty rows array - min_tvl_usd filter too high — all rows filtered out, count returns 0 - Invalid chain or protocol enum value — request validation error - Rate data stale beyond max_age_s — stale flag set to true in response ## How this service works One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI. ## Output A JSON object containing ranked rows of lending market data including protocol name, chain, asset symbol, supply APY, borrow APY, optional reward APY, utilization rate, and USD TVL; plus a best_by_asset summary, source freshness metadata, chain/protocol coverage map, and a disclaimer that rates are informational only. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "view": { "enum": [ "all", "best_stablecoin" ], "type": "string", "default": "all", "description": "all: every matching rate, highest supply APY first. best_stablecoin: USDC, USDT, DAI, USDS and USDe ranked by supply APY across the three protocols (canonical token addresses only)." }, "limit": { "type": "integer", "default": 50, "maximum": 200, "minimum": 1, "description": "Rows returned, 1-200 (default 50)." }, "assets": { "anyOf": [ { "type": "array", "items": { "type": "string", "pattern": "^[A-Za-z0-9._-]{1,20}$" }, "maxItems": 20 }, { "type": "null" } ], "default": null, "description": "Optional asset symbols such as USDC or WETH (case-insensitive, at most 20).
