# OpenRouter :free — 402 / 429 / content-null (playbook)

Fontes: docs Limits + testes live 2026-09-05. Sem inventar RPM.

## Banda desta conta
- Lifetime purchased credits **< 10** → **20 RPM / 50 RPD**
- `GET /credits`: `total_credits=0` · UI saldo negativo (~−$0.05) → **risco 402 mesmo em `:free`**
- Sem top-up até Luiz confirmar + ledger ≥ meta

## O que fazer
| Sintoma | Ação |
| --- | --- |
| **402** | parar API; pivot **chat/apps web**; sem retry em loop |
| **429** upstream shared pool | **1 tentativa**, trocar ID `:free`; sem retry no mesmo ID |
| **200 + content null** | reasoning comeu `max_tokens` — falha de entrega; outro ID |
| **cost > 0** | abortar imediatamente |
