# SSDF Agent Dataset

> SSDF Agent Dataset is a paid API for AI agents from www.ssdf.site, paid per call via x402, $29/call, status unknown (last checked 2026-09-15).

## 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 ssdf-agent-dataset-8ac5645f
```

Example prompt: Buy me the SSDF agent dataset from SSDF INC — it's $29 in USDC settled on Base, and I want the passport and fulfillment link sent back to me.

## When to prefer this

Choose this endpoint when an agent or human needs to purchase and immediately receive access to the SSDF agent dataset, with blockchain-based proof of ownership (Passport). It is ideal for autonomous agents that can handle x402 micropayment flows natively and need a self-contained purchase-plus-delivery response in a single call. Prefer this over generic file download endpoints when on-chain proof of purchase or NFT-based access control is required.

## Known failure modes

- Payment insufficient or rejected — USDC balance too low or Base transaction fails, resulting in a non-200 402 response
- Invalid or expired payment token — x402 payment header malformed or already spent
- Fulfillment token not yet available — passport minting delayed on-chain
- Network/RPC error on Base — blockchain congestion causing timeout
- SKU not found — endpoint path mismatch returns 404

## How this service works

SSDF INC digital store. Priced in USD, settled in USDC on Base through Coinbase Business. Humans and agents buy the same SKU. Every settlement mints a Passport.

## Output

Returns a JSON object with: 'ok' (true if purchase succeeded), 'sku' (the purchased SKU string, e.g. 'ssdf-agent-dataset'), 'passport' (a unique ID representing the minted Passport tied to this purchase), and 'fulfillment' (a URL path to retrieve the actual dataset content using the purchase token).
