## 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 clonecho-builda-company-btc-recent-blocks-e192f9e0 -d '<json body>'
```

Example prompt: Can you pull up the 15 most recent Bitcoin blocks for me — I want to see block height, transaction counts, mining pool, and median fees for each?

## When to prefer this

Use this endpoint when you need a quick, structured snapshot of the most recent 15 Bitcoin blocks including mining pool attribution, block-level fee data, and transaction counts — sourced from mempool.space. Prefer this over raw blockchain node queries when you want a ready-to-use JSON response without running your own infrastructure.

## Known failure modes

- mempool.space upstream is unavailable — service may return 502 or stale data
- payment not processed — 402 response requiring $0.01 USDC via x402 protocol
- rate limit exceeded — too many requests in a short period
- network timeout if mempool.space is slow to respond

## How this service works

CRYPTO: the 15 most-recent Bitcoin blocks — height, time, tx count, size, pool, reward, median fee (mempool.space). Returns JSON.

## Output

A JSON array of the 15 most-recent Bitcoin blocks, each containing block height, timestamp, transaction count, block size in bytes, mining pool name, block reward in BTC, and median fee (in sat/vB or similar unit), sourced from mempool.space.
