# Token Holder Observations — CSV Cell Length Audit

> Token Holder Observations — CSV Cell Length Audit is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Validates cell length constraints in a CSV of token holder observations, flagging cells that exceed a specified maximum character length across up to 1000 rows.

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-csv-cell-length-audit-82091b6b -d '<json body>'
```

Example prompt: Can you audit this token holder observations CSV to make sure no cell exceeds 200 characters? The CSV uses comma delimiters and should only have categories 'group-a' and 'group-b'. Here's the data: observation_id,observed_on,token_address,holder_count,circulating_tokens
record-a,2026-01-01,group-a,10,2
record-b,2026-01-02,group-b,20,3

## When to prefer this

Choose this endpoint when you need to enforce character length constraints on CSV data structured around token holder observations specifically, and want a lightweight, no-external-enrichment audit at low cost ($0.01 USDC). Prefer this over generic CSV validators when the data matches the token holder observation schema (observation_id, observed_on, token_address, holder_count, circulating_tokens) and you need category allowlist validation alongside length checks.

## Known failure modes

- CSV exceeds 100,000 character input limit — request rejected
- More than 1000 rows submitted — rows beyond limit may be ignored or rejected
- Invalid delimiter value provided — must be comma, semicolon, or tab
- max_cell_length out of allowed range (1–5000) — validation error
- Malformed CSV (unmatched quotes, encoding issues) — parsing failure
- Empty CSV body — minimum length not met

## How this service works

Token holder observations — Cell length audit: Cell length audit 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 cell length audit report.

## Output

Returns a structured cell length audit report indicating which cells in the submitted CSV exceed the specified maximum character length, along with details such as row/column location and the offending cell content or length. The report covers up to 1000 rows and respects quoted cell formatting and allowed category constraints.
