x402 Bazaar AI Field Extractor

Use this endpoint when you need to extract specific named fields from free-form, unstructured text and want a clean JSON response without building your own prompt engineering. Ideal for parsing contact info, form submissions, emails, or any prose where you know the field names you want. Prefer over general LLM calls when you want a guaranteed structured output at a fixed low cost per call via x402 micropayment.
