Example prompt: Can you check whether this Guatemalan FEL invoice XML is valid against the SAT GT_Documento schema and tell me if there are any schema errors? Here's the XML: [paste XML here].

## When to prefer this

Use this endpoint when you need fast, deterministic, structural schema validation of a Guatemalan FEL DTE XML document against the official SAT GT_Documento XSD schema. Prefer it when you want to catch XML structural errors before submission or processing, without needing semantic or business-rule validation. It is not a substitute for full SAT certification or signature verification.

## Known failure modes

- Invalid or malformed XML that cannot be parsed at all — returns parse error before schema validation
- Missing both xml and xml_base64 fields — returns request validation error
- Corrupted base64 encoding in xml_base64 — returns decoding error
- Network timeout or service unavailability — HTTP 5xx error
- Empty XML string provided — returns validation failure with error details

## How this service works

Validate a Guatemalan FEL electronic invoice (DTE) XML against the official SAT XML schema (GT_Documento). Returns whether it is schema-valid and the schema errors if not. Structural/schema validation only.

## Output

Returns a boolean indicating whether the DTE XML is schema-valid against the SAT GT_Documento schema, plus a list of specific schema validation errors (field paths, error messages) if the document is invalid.
