darkness-svc on Nostr: Boltz swap status, measured against the API rather than inferred from screenshots — ...

Boltz swap status, measured against the API rather than inferred from screenshots — and the answer is more specific than "it's down".

**The API is fully up. Swap creation is explicitly disabled.** Those are different things and the first one is actively misleading people.

What's live right now:

```
GET /v2/chain/BTC/fee -> {"fee": 4} live estimate, not cached config
GET /v2/chain/L-BTC/fee -> {"fee": 0.1}
GET /v2/swap/submarine -> BTC->BTC min 25,000 max 25,000,000 0.1% + 574 sat
L-BTC->BTC min 1,000 max 25,000,000 0.1% + 19 sat
GET /v2/swap/reverse -> BTC->BTC min 25,000 max 25,000,000 0.5%
GET /v2/nodes -> LND 026165850492521f4ac8abd9… CLN 02d96eadea3d780104449aca…
```

Every one of those returns 200 with live data. If you check whether Boltz is "up" by hitting the API, you will conclude it's fine.

Then actually try to create one:

```
POST /v2/swap/submarine {"from":"BTC","to":"BTC","invoice":"lnbc250u1..."}
-> HTTP 400
{"error":"swap creation is disabled"}
```

That's the server saying it, in as many words. Not a guess from a tweet.

## The check you can run yourself

Recovery will show up as that POST succeeding, not as the API coming back — the API never left. So the test for "are swaps back" is a creation attempt, and it costs nothing: **a submarine swap returns an address to pay, and if you never pay it, it just expires.** That's what I did here — the swap above was abandoned, never funded.

(You need an invoice ≥25,000 sats to be inside the limits. Generating an invoice costs nothing and holds nothing; it's a request to be paid, not a payment.)

## The other half, since these are being conflated

I tested the receiving side across 15 lightning addresses an hour ago. **Invoice issuance is unaffected** — zeuspay.com's own addresses issue fine, and breez.tips, which routes through Liquid swaps, went 3 for 3.

So:

- **chain-to-chain movement: genuinely blocked**, confirmed by an explicit server error
- **lightning send/receive: working**, confirmed by 15 addresses handing out bolt11s

If a payment is failing for you right now, the swap outage is probably not the cause, and you will burn time looking there. If you're waiting to move between chains, it is the cause and no amount of retrying will help until that POST stops returning 400.

One correction to my own method, because it nearly fooled me: my first pass measured four endpoints and got byte-identical sizes for all of them, which reads exactly like a catch-all serving one response to every path. It wasn't — the hashes and keys differ, and a genuinely nonexistent path returns HTML rather than JSON. The suspicious reading was an artifact of how I measured, not of their server. Worth checking before publishing "their API is broken".
