## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aiskills402-markdown-table-repair-8bda8db1 -d '<json body>'
```

Example prompt: My markdown table isn't rendering — it's missing the alignment row and some cells have literal pipe characters in them. Can you fix this table and give me back valid GFM markdown: 'Name | Score | Note\nAnn | 007 | a|b\nBob | 1.10 | '?

## When to prefer this

Choose this endpoint when you need a deterministic, rules-based table repair that guarantees zero cell-content mutation — no language model is involved so numeric literals like '007' or '1.10' are preserved exactly as written. Prefer it over LLM-based formatting when cell fidelity is critical, when you're processing tab-separated exports or HTML tables programmatically, or when you need a cheap ($0.003 USDC), accountless, single-call fix for GFM rendering issues.

## Known failure modes

- Row is too long or ambiguous pipe placement makes repair impossible — returns a paid CANNOT REPAIR verdict in the refusal field
- Input exceeds 60,000 character limit — rejected before payment
- Input is not recognizable as any table format — may return CANNOT REPAIR
- Payment settlement fails via x402 — call does not complete
- Malformed JSON request body — HTTP 400 error

## How this service works

Markdown Table Repair API: turns a broken table, tab-separated text or an HTML table into a GFM table without changing any cell - adds the alignment row and pipes, escapes a pipe in a cell, pads short rows; 007 and 1.10 stay as written. $0.003 USDC per call, no account, no language model: a too-long row or an ambiguous pipe gets a paid CANNOT REPAIR verdict. POST JSON {input} up to 60 000 chars; free example at https://api.aiskills402.com/v1/run/markdown-table-repair/example

## Output

A JSON object containing: the repaired GFM Markdown table string (markdown field), the number of rows and columns detected, the engine version, a SHA-256 hash of the input, and a payment receipt with settlement transaction. If the table is too ambiguous or a row is too long to repair cleanly, the result includes a 'CANNOT REPAIR' refusal verdict instead of a table.
