> From April 4 noon PT, Claude Pro/Max/Team OAuth tokens no longer power third-party agent harnesses (e.g. OpenClaw) — API keys or extra-usage bundles required; one-month plan credit for impacted users. The trade: subscription economics were built for chat, not always-on agents — Anthropic protects margin; third-party agent UX breaks until rekeyed.

Agent frameworks that rode Claude **subscription OAuth** as cheap always-on compute just hit the metering wall. Anthropic’s frame is explicit: **flat-rate chat plans are not an agent hosting subsidy**.

**Anthropic** began enforcing (April 4, **12:00 PM PT**) a block on using Claude **Pro, Max, and Team** subscription tokens with third-party agent tools/harnesses such as **OpenClaw**. Announced April 3 via Boris Cherny (Claude Code) on X/Threads. Workarounds: dedicated **API key** (e.g. Sonnet 4.6 ~$3/$15 MTok cited in coverage) or discounted **extra usage bundles** (up to ~30% off volume). Impacted subscribers got a **one-time credit** equal to one month of their plan.

## What broke / what still works

| Path | Status after enforcement |
|------|--------------------------|
| **Third-party harness + sub OAuth** | Blocked |
| **API key** | Full token pricing |
| **Extra usage bundles** | Discounted add-on volume |
| **Native Claude products** | Subscription model unchanged for intended interactive use |

Coverage estimated **>135,000** active OpenClaw instances on Claude subs — **secondary estimate**, not Anthropic disclosure. Developers reported agents failing until reconfigured.

## Claims vs checks

Enforcement timing and credit policy are from **Anthropic announcements** (Cherny) plus **The Next Web** and developer reports. Cost-unsustainability rationale is **company**. OpenClaw instance counts and Reddit/Medium impact stories are **ecosystem reporting**.

## Limits

- Exact detection heuristics for “third-party harness” not fully public.
- Bundle discount math varies by plan.
- May slow some third-party innovation while clarifying product boundaries.
