# Zhipu (BigModel / 智谱) Keys

## Status: FREE TIER ONLY

**GLM-5.2 (paid flagship): 0 usable.** Every candidate returns HTTP 429
`code 1113 余额不足或无可用资源包,请充值` against `glm-5.2` — these are
real authenticated accounts, but none carry balance or a paid resource
package for GLM-5.2.

**Free tier: 207 usable.** All 207 authenticated accounts successfully serve
chat completions on Zhipu's permanently-free models:

| Model | Keys that serve it |
|---|---|
| `glm-4-flash` | 207 (all) |
| `glm-4.5-flash` | 12 (subset also returns content) |

`glm-4-flash` is Zhipu's permanently-free model (rate-limited per account),
so these are stable white-label keys for low/medium traffic. They are NOT
dead — they authenticate and return real completions — they simply have no
paid balance for GLM-5.2 / GLM-4.6 / etc.

## Endpoint
- Base: `https://open.bigmodel.cn/api/paas/v4`
- Auth: `Authorization: Bearer <key>`
- Format: `<32hex>.<16alnum>` (id.secret JWT-style)
- Chat: `POST /chat/completions`

## Suggested routing in NewAPI / one-api
- Channel type: Zhipu / BigModel
- Models: `glm-4-flash`, `glm-4.5-flash`
- Do NOT map `glm-5.2` to these channels — every key returns 429/1113 on it.
- Load-balance across the 207 keys to absorb per-account rate limits.

## Files
- `keys.json` — full structured records (with source + status)
- `keys.env` — `ZHIPU_API_KEY_NNN=...` ready to source
- `key_NNN.txt` — one key per file
- `free_model` field indicates which free model verified 200 for that key.
