Two bugs caused all xai providers to show 'error' in the monitor:
1. Double /v1 in URL: models.json baseUrl is https://api.x.ai/v1 (OpenAI-
compatible convention), and the probe was appending /v1/chat/completions,
producing https://api.x.ai/v1/v1/chat/completions → HTTP 4xx.
Fix: strip trailing /vN from baseUrl before constructing the probe URL.
2. Wrong model: probe used grok-3-mini, which requires specific x.ai
console permissions not granted to our keys. Keys have access to
grok-4-1-fast-reasoning only.
Fix: use GET /v1/models instead — lightweight, no model guessing,
returns 200 (valid key) or 401 (invalid). Includes available models
in result for visibility.
158/158 tests pass (unit tests for parseXaiHeaders unchanged).
Implements modular provider probing with two distinct header schemas:
- Teams direct (unified schema): 5h/7d utilization floats, status, reset countdown
- Shelley proxy (classic schema): token/request counts + Exedev-Gateway-Cost (USD/call)
- api-ateam: reports no billing data (confirmed non-existent by recon)
Key: uses claude-haiku-4-5-20251001 for minimal probe calls (1 token).
Rate-limit headers present on ALL responses (200 and 429).
113/113 tests passing.
Built from Face recon (trentuna/a-team#91) — live header capture confirmed
unified schema with utilization floats replaces old per-count schema.
