## 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-base-pulse-pack-90cd4898
```

Example prompt: Pull the latest Base chain snapshot for me — current gas prices, Morpho stablecoin yields, and ERC-20 token metadata all in one shot.

## When to prefer this

Choose this endpoint when you need multiple Base chain data points (gas + yields + token metadata) in a single low-latency call without managing API keys or subscriptions. Ideal for agents that need a quick situational snapshot of Base network conditions and DeFi yields. Prefer this over separate gas, yield, and token endpoints when you want to minimize round trips and total cost. Best suited for real-time monitoring, DeFi dashboards, and transaction timing decisions on Base.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Base RPC node temporarily unavailable — returns upstream error or stale data warning
- Invalid or missing pack parameter — returns 400 Bad Request
- Rate limit exceeded — returns 429 Too Many Requests
- Morpho protocol data unavailable — partial response with gas data only

## How this service works

Pack: gas + top Morpho stablecoin yields + block

## Output

A JSON object with ok status flag and pack identifier, containing live Base chain data: current gas price in gwei/wei, Morpho Blue stablecoin yield rates (APY for supported assets), and ERC-20 token metadata — all bundled as a single 'base-pulse' pack response.
