# 429 — one of five limits was hit

- HTTP: `429`

- Encabezado `Retry-After`: a veces

## Qué pasó

The request was rejected by a limit. The action was not performed, no order was created, and no money was charged. For three of the five sources the body is identical and useless: `{"success": false, "message": "Too many attempts. Please wait a moment and try again."}`.

## Por qué

FIVE independent mechanisms respond with 429, and each one is resolved differently: the key rate limit (request frequency), the key token quota (generation volume), the subscription usage limit, the limit on concurrently active tasks, and the cooldown after a series of content blocks. Blind exponential backoff helps only with the first two; on the concurrency limit and the policy cooldown it just burns time.

## Qué hacer

Triage by two signals, both visible in the response itself. First — whether the body has a `reason`: no `reason` means the key rate limit. Second — whether there is a `Retry-After` header: it comes ONLY with `token_quota_exceeded` and `policy_cooldown_active`. The combination of these two signals distinguishes all five sources unambiguously.

## Siguiente petición

`GET /usage` — the subscription limits in effect and current consumption, including the entry with `limit_type: "concurrent"`. The limits of the key itself are not included: they are in the developer section.
