## 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 basefeed-yield-scout-morpho-stablecoin-yield-pack-09f65766

Example prompt: What are the top 5 stablecoin yield opportunities on Morpho Blue right now on Base, only showing markets with at least $500,000 TVL?

## When to prefer this

Use this endpoint when you need live, on-chain Morpho Blue stablecoin yield data specifically on Base chain and want to filter by TVL or watch specific tokens. Prefer this over generic DeFi aggregators when you need pay-per-call access with no API key, or when building agents that need real-time Base chain yield data without a subscription commitment.

## Known failure modes

- Payment not included or insufficient — returns 402 Payment Required
- Invalid or unsupported query parameters — returns 400 Bad Request
- Morpho Blue data temporarily unavailable upstream — returns 503 or degraded response
- min_tvl too high — returns empty results set with ok: true but no markets
- Rate limit exceeded — possible 429 response

## How this service works

Live Base gas, Morpho stablecoin yields, and ERC-20 token metadata. Pay per call in USDC on Base through x402. No signup. No API key.

## Output
