# ANSI X12 Test Data
Structurally complete X12 837P claim documents (ISA, GS, ST, BHT, NM1, CLM, SE, GE, IEA) with varying control numbers. Synthetic claims; not real patients or payers.
Free to use under **CC0-1.0** — public domain dedication, no attribution required.
## Files
- `x12-small.json` / `x12-small.csv` — 100 rows (documents: 25)
- `x12-medium.json` / `x12-medium.csv` — 2,000 rows (documents: 250)
- `x12-large.json` / `x12-large.csv` — 20,000 rows (documents: 2,500)
Deterministic: the same size always produces the same rows.

## Security: adversarial corpus
This dataset ships a catalogued **adversarial corpus** of 12 hostile inputs
(injection, XXE, resource exhaustion, encoding attacks, validation bypass, structural confusion,
and prompt injection for AI agents) with the safe expected behaviour. See
[`adversarial/`](adversarial/) or the [hub](https://stanzaapi.com/datasets/adversarial).
