## 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 eudata402-bitcoin-network-data-mempool-space-bb0d8f45
```

Example prompt: What are the current recommended Bitcoin fee tiers right now — low, medium, and high priority?

## When to prefer this

Use this endpoint when you need live Bitcoin network fee data, transaction confirmation status, or address balance lookups without managing your own Bitcoin node or API key. Prefer over raw RPC calls for quick agent integrations needing mempool.space data on a pay-per-call basis.

## Known failure modes

- Invalid or malformed txid/address returns an error object
- Unknown txid (not in mempool or blockchain) returns null or not-found error
- Network unavailability of mempool.space upstream causes 5xx response
- Missing required 'id' field when kind=tx or kind=address causes validation error
- Unrecognized 'kind' value defaults to fees or returns error

## How this service works

Bitcoin network data (mempool.space): recommended fee tiers, or a tx / address lookup. POST {kind?: fees|tx|address, id?}. Returns fee tiers or the tx/address object.

## Output

Returns either: (1) a fees object with recommended sat/vB fee tiers (low, medium, high priority) for the current mempool state, (2) a transaction object with details like confirmation status, block height, inputs/outputs, and fees, or (3) an address object with balance, transaction count, and history — all sourced from mempool.space.
