## 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 agentic-saas-x402-seller-manifest-cb68a6ed
```

Example prompt: Fetch the signed manifest from the Agentic-SaaS x402 seller on Base so I can see what endpoints are available, what they cost in USDC, and which wallet address to pay.

## When to prefer this

Use this endpoint as the first step whenever an agent needs to interact with this x402 seller: it is the cheapest call ($0.01) and returns the authoritative payment address, network, and product catalogue needed before making any higher-value call like the drift audit ($0.05) or integration brief ($0.25). Prefer it over hardcoding payment details, since the signed manifest is the canonical source of truth for the seller's current configuration on Base.

## Known failure modes

- 402 Payment Required if payment header is missing or malformed
- Invalid method — only GET, HEAD, DELETE accepted
- Network mismatch if agent targets wrong chain
- Stale manifest if canary version has been rotated
- Worker timeout or cold-start latency on Cloudflare edge

## How this service works

## Output

A JSON object containing the manifest ID, human-readable name, the seller's USDC payout address on Base (eip155:8453), network identifier, and version string — everything an agent needs to construct a valid x402 payment before calling a premium endpoint.
