# ProYield Yield API

> ProYield Yield API is a paid API for AI agents from pyd.fi, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Returns live DeFi stablecoin lending rates with safety tiers, vault blend targets, fixed-pool and satellite sleeve rates, and full provenance metadata for risk-adjusted USDC yield decisions.

## Facts

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 proyield-yield-api-6f94a987
```

Example prompt: What are the current ProYield stablecoin lending rates across all venues right now, including the safety tiers, vault blend target, and which sources the data came from?

## When to prefer this

Choose this endpoint when you need current, curated DeFi stablecoin lending rates with explicit safety tier classifications and a pre-computed risk-adjusted blend target, rather than raw on-chain data or unfiltered protocol APIs. Ideal when an agent needs a trusted USDC yield anchor with provenance rather than having to aggregate and evaluate protocol data independently.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Upstream DeFi protocol data temporarily unavailable — may return stale or partial rate data
- Rate limit exceeded — returns 429 Too Many Requests
- Network timeout if upstream venue data feeds are slow

## How this service works

Live Pro Yield yield intelligence: curated stablecoin lending venue rates with safety tiers, the vault blend target, fixed-pool and satellite sleeve rates, and full provenance (source + timestamps). Use when an agent needs current DeFi stablecoin yields or a risk-adjusted USDC rate anchor.

## Output

A structured JSON response containing live stablecoin lending venue rates organized by safety tier, the vault blend target rate, fixed-pool rates, satellite sleeve rates, and full provenance data including data sources and timestamps for each rate.
