```

Example prompt: I'm getting porosity in my TIG welds on aluminum — what's causing it and how do I fix it?

## When to prefer this

Choose this endpoint when an agent needs authoritative, on-demand answers to specific welding process, defect, metallurgy, or AWS symbol questions. Ideal for manufacturing assistants, fabrication shop bots, or engineering agents that occasionally need welding expertise without maintaining a full welding knowledge base. At $0.15 per call it is cost-effective for infrequent, targeted queries.

## Known failure modes

- Empty or malformed 'reply' field returns an error
- Question outside welding/metallurgy domain may return an out-of-scope response
- Payment failure via x402 protocol blocks the call
- Ambiguous question may yield a generic or partially relevant answer
