Feature Request: Add xAI/Grok support for custom/manual logging

[karthvp]

Summary

Add xAI (Grok) provider support for the custom/manual logging endpoint, enabling cost calculation for xAI requests logged via the Manual Logger SDK.

Current Behavior

When using the Manual Logger (@helicone/helpers) or the /custom/v1/log endpoint with xAI/Grok models:

• Provider shows as "unknown" in the dashboard
• Cost calculation returns "Cost Unsupported"
• The provider: "X" field in the payload is not recognized

Expected Behavior

• Provider should be identified as "X" or "xAI"
• Cost calculation should work using the existing xAI pricing in packages/cost/providers/x/index.ts
• Ideally, a dedicated /x/v1/log route (similar to /oai/v1/log, /anthropic/v1/log)

Context

The cost package already has xAI pricing defined with URL pattern matching for the gateway (/^https:\/\/api\.x\.ai/), but this pattern matching doesn't apply to the custom logging endpoint.

The providerRoutes map in the SDK only includes:

• OPENAI → oai
• ANTHROPIC → anthropic
• GOOGLE → googleapis

Adding X → x (or similar) would enable xAI support.

Workaround

Currently, the only way to get xAI cost tracking is through the gateway (x.helicone.ai), which isn't always feasible for async/manual logging use cases.
