# Stealth API
|
|
|
|
`stealth-api` is the Rust HTTP transport layer for Stealth. It connects to a
|
|
running `bitcoind` via JSON-RPC, imports descriptors into temporary wallets,
|
|
builds a transaction graph, and runs privacy detectors from
|
|
`stealth-engine`.
|
|
|
|
## Running
|
|
|
|
```bash
|
|
# Stop any old API process, then start the current source build
|
|
pkill -f 'target/debug/stealth-api' 2>/dev/null || true
|
|
|
|
# Auto-detects local bitcoind RPC port (prefers 18443, then 8332/18332/38332)
|
|
# and uses credentials from bitcoin.conf or local cookie files.
|
|
cargo run --bin stealth-api
|
|
```
|
|
|
|
Set auth explicitly with username/password:
|
|
|
|
```bash
|
|
STEALTH_RPC_URL=http://127.0.0.1:8332 \
|
|
STEALTH_RPC_USER=user \
|
|
STEALTH_RPC_PASS=pass \
|
|
cargo run --bin stealth-api
|
|
```
|
|
|
|
Or use a cookie file:
|
|
|
|
```bash
|
|
STEALTH_RPC_URL=http://127.0.0.1:8332 \
|
|
STEALTH_RPC_COOKIE=~/.bitcoin/.cookie \
|
|
cargo run --bin stealth-api
|
|
```
|
|
|
|
Configure the listen address with `STEALTH_API_BIND` (default `127.0.0.1:20899`).
|
|
|
|
If you see `Connection refused (os error 111)`, either:
|
|
1. an old `stealth-api` process is still running, or
|
|
2. `bitcoind` RPC is not reachable on the detected/configured URL.
|
|
|
|
## API
|
|
|
|
### `POST /api/wallet/scan`
|
|
|
|
Accepts one mutually-exclusive source:
|
|
|
|
| Field | Type | Description |
|
|
|-------|------|-------------|
|
|
| `descriptor` | `string` | Single output descriptor |
|
|
| `descriptors` | `string[]` | Multiple descriptors |
|
|
| `utxos` | `UtxoInput[]` | Raw UTXO set |
|
|
|
|
**Descriptor scan flow:** creates a blank watch-only wallet, imports the
|
|
descriptor(s) with a full blockchain rescan, builds a `TxGraph`, runs all
|
|
17 detectors, then cleans up the temporary wallet.
|
|
|
|
**UTXO scan flow:** resolves each UTXO's address from the node, builds a
|
|
partial transaction graph, and runs applicable detectors.
|
|
|
|
#### Example (real descriptor from Bitcoin Core)
|
|
|
|
```bash
|
|
RPC="bitcoin-cli -regtest -rpcport=18443 -rpcuser=localuser -rpcpassword=localpass"
|
|
WALLET="scanwallet_$(date +%s)"
|
|
|
|
$RPC createwallet "$WALLET" >/dev/null
|
|
ADDR="$($RPC -rpcwallet="$WALLET" getnewaddress)"
|
|
DESC="$($RPC -rpcwallet="$WALLET" getaddressinfo "$ADDR" | jq -r '.desc')"
|
|
|
|
curl 'http://localhost:20899/api/wallet/scan' \
|
|
-H 'content-type: application/json' \
|
|
-d "{\"descriptor\":\"$DESC\"}" | jq
|
|
```
|
|
|
|
#### Responses
|
|
|
|
| Status | Meaning |
|
|
|--------|---------|
|
|
| `200` | Scan completed — body is a `Report` |
|
|
| `400` | Invalid input (bad descriptor shape, empty UTXOs, …) |
|
|
| `502` | bitcoind RPC unavailable/auth failed/connection failed |
|
|
|
|
## Environment variables
|
|
|
|
| Variable | Description |
|
|
|----------|-------------|
|
|
| `STEALTH_API_BIND` | Listen address (default `127.0.0.1:20899`) |
|
|
| `STEALTH_RPC_URL` | bitcoind RPC endpoint (overrides auto-detection) |
|
|
| `STEALTH_RPC_USER` | RPC username (otherwise read from `bitcoin.conf` when available) |
|
|
| `STEALTH_RPC_PASS` | RPC password (otherwise read from `bitcoin.conf` when available) |
|
|
| `STEALTH_RPC_COOKIE` | Path to `.cookie` file (otherwise API auto-detects common local cookie locations) |
|
|
|
|
## E2E test (regtest)
|
|
|
|
The API includes an end-to-end regtest integration test that:
|
|
1. creates wallets,
|
|
2. gets a real descriptor from `bitcoind`,
|
|
3. scans once with no history (`summary.clean = true`),
|
|
4. creates/mine transactions,
|
|
5. scans again and asserts findings (`summary.clean = false`).
|
|
|
|
Run it with:
|
|
|
|
```bash
|
|
cargo test -p stealth-api scan_descriptor_clean_then_findings_after_regtest_activity -- --nocapture
|
|
```
