## 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 desk-lead-x402-bsc-yield-pools-acde65c2
```

Example prompt: Can you pull the current yield pool data from the BSC Yield API on DESK LEAD — I want to see what USDC pools are available on Binance Smart Chain right now?

## When to prefer this

Use this endpoint when you need current yield pool data specifically on Binance Smart Chain (BSC) and want a micropayment-gated research API with low per-call cost ($0.25 USDC). Prefer this over generic DeFi aggregators when you need a structured JSON response suitable for agent consumption and optionally want to filter by a specific asset like USDC.

## Known failure modes

- Empty pools array returned if no pools match the requested asset filter
- Payment not included or invalid — returns 402 Payment Required with x402 challenge
- Invalid asset query parameter format may return empty results silently
- Network mismatch — primary v2 only accepts Base (eip155:8453); legacy BSC payment path requires correct header setup
- Rate limiting or worker errors may return 5xx responses

## How this service works

Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.

## Output

Returns a JSON object with an 'ok' boolean, a 'pools' array containing yield pool entries on BSC (may include pool name, asset, APY, and other metrics), and a 'product' field identifying this as the bsc_yield data product. Pool array may be empty if no matching pools are found.
