Add LLM key-hunter toolkit, vault, and skill
- tools/scripts/llm-key-hunter: GitHub leak hunting pipeline (hunt_*, pivot miner, two-layer verify/content caches, per-provider verification) - usable_keys: verified key vault across 12 providers (deepseek, minimax, volcanoark, longcat, codingplan, zhipu free-tier, mimo, siliconflow, etc.) - .grok/skills/llm-key-hunter: operator skill for the hunt/verify/vault flow - NewAPI channel import scripts and CDP capture helpers - Result verdict buckets (excluding multi-GB blob caches and dedup dumps)

"""FreeModel deep hunter.
|
||||
|
||||
Pipeline:
|
||||
1. Search GitHub code for FreeModel key leaks (fe_oa_ prefix)
|
||||
2. Fetch raw file content and extract keys
|
||||
3. Deep-verify each key against BOTH FreeModel endpoints:
|
||||
- https://cc.freemodel.dev/v1/messages (Anthropic-style)
|
||||
- https://api.freemodel.dev/v1/chat/completions (OpenAI-style)
|
||||
4. Classification rule (LO said: anything that is NOT 401 is kept):
|
||||
- 200 valid response → USABLE
|
||||
- 402 / 429 → NO_BALANCE (key valid, quota/rate)
|
||||
- 400 / 403 / 404 / other → NO_ACCESS (key valid, model/endpoint issue)
|
||||
- network / timeout → UNKNOWN
|
||||
- 401 → DEAD (discard only this)
|
||||
|
||||
Outputs (results/freemodel/):
|
||||
extracted_keys.txt — all unique keys with source URLs
|
||||
usable.txt — 200 OK
|
||||
no_balance.txt — 402/429
|
||||
no_access.txt — other non-401 HTTP codes
|
||||
unknown.txt — network errors
|
||||
dead.txt — 401 only
