## Operations

### Address

#### GET `/api/address/hash-prefix/{addr_type}/{prefix}`

Address hash-prefix matches

Find addresses by address type and by the first 1-16 hex nibbles of RapidHash v3 over the raw address payload bytes. Intended for privacy-preserving client-side wallet discovery without sending raw addresses or xpubs. Fetch metadata with `GET /api/address/{address}`.

Parameters:
- `addr_type` (path, OutputType, required)
- `prefix` (path, string, required): First 1–16 hexadecimal nibbles of the RapidHash v3 hash over the raw address payload bytes.

Returns: JSON `AddrHashPrefixMatches`

```bash
curl -s "https://bitview.space/api/address/hash-prefix/<addr_type>/<prefix>"
```

#### GET `/api/address/{address}`

Returns: JSON `NextBlockHash`

```bash
curl -s "https://bitview.space/api/mempool/hash"
```

#### GET `/api/mempool/price`

```

#### GET `/api/v1/mempool/block-template`

Projected next block template

Bitcoin Core's `getblocktemplate` selection: full transaction bodies in GBT order with aggregate stats. The returned `hash` is an opaque content token; pass it to `GET /api/v1/mempool/block-template/diff/{hash}` to fetch deltas instead of refetching the whole template.

Returns: JSON `BlockTemplate`

```bash
curl -s "https://bitview.space/api/v1/mempool/block-template"
```

#### GET `/api/v1/mempool/block-template/diff/{hash}`

Block template diff since hash

Delta of the projected next block since `<hash>`. `order` is the full new template in order: each entry is either a number (index into the prior template the client cached at `<hash>`) or a transaction object (new body to insert at this position). Walk `order` once to rebuild; `removed` is a convenience list of txids that left so clients can evict cached bodies. After applying, use the response `hash` as `<hash>` on the next call to keep iterating. Returns `404` when `<hash>` has aged out of server history; clients should fall back to `GET /api/v1/mempool/block-template`.

Parameters:
- `hash` (path, NextBlockHash, required)

Returns: JSON `BlockTemplateDiff`
