2026 OpenClaw Frontend Practice:
Align /v1/models on a Remote Mac Gateway for OpenAI-Compatible Clients — Monorepo Smoke Checklist
Audience: engineers wiring OpenClaw in front of LLM providers while keeping OpenAI SDKs and HTTP clients unchanged. This runbook keeps /v1/models honest on a rented remote Mac, ties monorepo diffs to smoke steps, and plugs into PR checks without leaning on hosting deploy hooks. Cross-check the blog index, OpenClaw PR summary flow, and frontend release discipline when UI and gateway ship together.
01 Why /v1/models breaks silently
1) Clients cache the model list once at startup. A gateway that serves chat correctly but returns a malformed or empty data array still looks healthy until someone opens model pickers.
2) Path drift is common when reverse proxies strip prefixes. Teams verify /v1/chat/completions first and forget that SDKs call /v1/models with the same base URL and headers.
3) Alias tables diverge across packages after refactors. Without a single source of truth, the gateway exposes ids that internal tools no longer recognize.
02 Client expectation versus gateway behavior
OpenAI-compatible clients assume a stable JSON shape. Use the matrix below before promoting a gateway build.
| Topic | OpenAI-compatible client | Gateway responsibility |
|---|---|---|
| Endpoint | GET /v1/models on the same baseURL as chat. |
Expose the route behind identical TLS and auth middleware so curl and SDKs agree. |
| Auth | Sends Authorization: Bearer … unless explicitly disabled. |
Reject early with 401 when the secret is missing; avoid redirect loops that swap POST for GET. |
| Shape | Expects { "object": "list", "data": [ { "id", "object", "created", "owned_by" } ] }. |
Preserve fields clients filter on; document any optional extensions. |
| Aliases | Users pick friendly labels mapped to provider ids. | Keep alias maps versioned beside gateway config so renamed models do not fork silently. |
When the matrix fails, fix routing before tuning provider quotas.
03 HowTo: install, route, aliases, monorepo map
- Install on the remote Mac. Clone your monorepo, run the package manager install from the repo root, and start the gateway with the same Node or Bun version pinned in CI.
- Export runtime parameters. Set
GATEWAY_BASEto the public origin,OPENAI_API_KEYto the token your clients use, and anyPROVIDER_*secrets required by OpenClaw. - Confirm routing. Ensure the HTTP server registers GET
/v1/modelsbefore optional telemetry routes so load balancers do not send traffic to the wrong handler order. - Load aliases from one module. Point gateway configuration at the shared package that both CLI and service import so renames propagate atomically.
- Map monorepo paths to smoke depth. Changes under
packages/gateway,apps/proxy, or shared auth middleware always trigger the full models probe. Documentation-only edits skip runtime smoke but still need lint. - Record artifacts. Save
models_smoke.jsonwith HTTP status, elapsed milliseconds, and sorted model ids for diffing across PR revisions.
04 Executable probes and parameters
Run these commands on the remote Mac shell so failures reproduce for reviewers.
- ▸Models GET:
curl -sS -H "Authorization: Bearer $OPENAI_API_KEY" "$GATEWAY_BASE/v1/models" -o models_smoke.jsonthenjq '.data[].id' models_smoke.json | sort. - ▸Header audit:
curl -sSI "$GATEWAY_BASE/v1/models"to confirm401without a token instead of accidental redirects. - ▸Diff gate:
git diff --no-index prior_models.txt current_models.txtafter exporting sorted ids to text files named by commit SHA. - ▸Scoped search:
rg "v1/models" packages apps -nafter refactors to catch stale Express or Fastify mounts. - ▸Chat sanity: optional one-shot chat probe shares auth and base URL, proving the session is not only healthy for GET.
Treat non-deterministic provider outages as flaky only after the direct upstream curl matches the gateway response body.
05 PR workflow hooks
Wire smoke output into the same automation you already use for structured summaries. Post models_smoke.json as a CI artifact, add a required check named gateway-models, and comment the sorted id list on the pull request when the diff is non-empty.
Label PRs that touch alias tables with area:models so reviewers expect a models check. For cross-cutting middleware changes, run the probe on a remote Mac job that mirrors production environment variables.
Link the NDJSON or JSON summary back to the ticket idempotently so reruns do not spam threads. This complements cache-focused OpenClaw flows without replacing hosting-specific pipelines.
06 Citable checks
The SDK base URL must end at the gateway root without trailing path segments that duplicate /v1.
Export lexicographically sorted model ids for review; unexpected reordering often signals merged duplicate configs.
Gateway or auth changes require models smoke; pure docs or marketing assets do not unless they alter env examples.
07 FAQ
Why does my client see HTTP 401 on /v1/models?
The gateway validates Bearer tokens for list routes as well as chat. Re-export the key in the remote Mac session, strip whitespace, and compare against the value embedded in local .env files committed only through secret stores.
Why is data empty while HTTP 200 returns?
Upstream sync may lag or filters may exclude hosts. Read gateway logs for provider throttling, then curl the provider directly with the same credentials to isolate failures.
How do monorepo edits relate to smoke scope?
Map each touched package to probes. Shared middleware edits rerun models and a minimal chat call; docs-only edits skip runtime smoke.
Need a Dedicated Mac for Gateway QA?
Run OpenClaw and browser-backed checks on real Apple hardware without shipping laptops. Start from the home page, read help without logging in, review pricing, then buy or rent when you need an isolated signing and networking profile for gateway work.
