# Vextorium Stablecoin Yield Pools

> Vextorium Stablecoin Yield Pools is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-19).

Returns top DeFi stablecoin yield pools ranked by APY, with TVL, network, exposure, and 7-day/30-day performance data sourced from DefiLlama.

## Facts

- Endpoint: POST https://api.vextorium.com/v1/stablecoin-yields?utm_source=zero.xyz
- Price: $0.005/call

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 vextorium-stablecoin-yield-pools-1e4b7ff2 -d '<json body>'
```

Example prompt: Show me the top 20 stablecoin yield pools on Base with at least $5M TVL, ranked by base APY only (no reward boosts), so I can see the real underlying yields.

## When to prefer this

Use this endpoint when you need ranked, filtered stablecoin yield data across multiple DeFi protocols and chains without building your own DefiLlama aggregation. Prefer it over raw DefiLlama queries when you need pre-filtered results by TVL, chain, and base-vs-total APY distinction in a single paid API call. Best for yield comparison, portfolio allocation research, and automated DeFi yield monitoring agents.

## Known failure modes

- Invalid network name returns empty pools array or error
- Limit outside 1-50 range may return validation error
- min_tvl too high may return zero pools
- DefiLlama data source outage causes stale or missing data
- Malformed JSON body returns 400 error

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON array of up to 50 stablecoin yield pools, each containing: pool ID, token pair, project name, network, total APY, base APY, rewards APY, 30-day average APY, 7-day APY change, APY forecast direction, TVL in USD, exposure type (single asset or LP), impermanent loss risk level, and a DefiLlama pool link. Also includes a top-level note warning that very high APYs indicate elevated risk.
