# Token Holder Observations — Invalid Row Export

> Token Holder Observations — Invalid Row Export is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Validates a CSV of token holder observations and exports a report of rows that fail declared contract rules (range, category, length constraints).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 token-holder-observations-invalid-row-export-df654807 -d '<json body>'
```

Example prompt: Check my token holder observations CSV for invalid rows — use comma as delimiter, flag any holder_count outside 0 to 1000000, and only allow categories 'group-a' and 'group-b'; here's the CSV data: observation_id,observed_on,token_address,holder_count,circulating_tokens\nrecord-a,2026-01-01,group-a,10,2.

## When to prefer this

Choose this endpoint when you have a structured CSV of token holder observations and need to identify which specific rows violate a declared data contract (numeric bounds, allowed category values, cell length limits) without any external enrichment. It is purpose-built for the token holder observation schema (observation_id, observed_on, token_address, holder_count, circulating_tokens) and is ideal as a lightweight, low-cost pre-ingestion quality gate or audit step. Prefer it over generic CSV validators when you need domain-specific category and range enforcement on holder data.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV contains fewer than 1 character — request rejected
- Delimiter mismatch causes incorrect parsing — all rows may appear invalid
- More than 1000 rows submitted — only up to 1000 rows evaluated
- allowed_categories array exceeds 100 items — request rejected
- max_cell_length set outside 1–5000 range — validation error
- Malformed CSV (unmatched quotes) — parsing error returned
- minimum greater than maximum — undefined or empty result set

## How this service works

Token holder observations — Invalid row export: Invalid row export for Token holder observations. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV invalid row export report.

## Output

A structured export report listing each invalid row from the submitted CSV, along with the specific rule violations (out-of-range numeric values, disallowed categories, cell length breaches). Up to 1000 rows are evaluated per call. Quoted cells are supported; no external data enrichment is performed.
