# Argo Hub Dataset Metadata Lookup

> Argo Hub Dataset Metadata Lookup is a paid API for AI agents from diomedes.tail1c6d58.ts.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-18).

Returns metadata (row count, name) for a named dataset hosted on the Argo Hub private GPU/data platform, paid via x402 USDC micropayment.

## Facts

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 argo-hub-dataset-metadata-lookup-587bca37
```

Example prompt: How many rows does the 'edgar-tickers' dataset have on Argo Hub? I'll pay with USDC if needed.

## When to prefer this

Use this endpoint when you need lightweight metadata (row count, name) about a specific named dataset on the Argo Hub platform before committing to a heavier data pull. Prefer it over full data retrieval endpoints when you only need to validate dataset existence or size. It is the right choice when paying per-call via x402 USDC micropayments on Base is acceptable and you need a fast, cheap lookup.

## Known failure modes

- Dataset name not found — 404 or empty response if the {name} path parameter doesn't match a hosted dataset
- Payment failure — x402 micropayment not settled, request blocked
- Invalid path parameter format — malformed or URL-encoded dataset name causes routing error
- Authentication/facilitator error — self-hosted USDC facilitator unavailable, payment cannot be verified

## How this service works

x402-paid LLM APIs on a private GPU fleet (Qwen3.8-27B, VL 30B). USDC on Base, settle in seconds via a self-hosted facilitator. Unique: verifier-gated correctness on /premium/deep — wrong answers regenerated free. First call free, no wallet: POST /premium/first.

## Output

A JSON object containing the dataset name (string) and the total row count (integer), e.g. {"dataset": "edgar-tickers", "rows": 10407}.
