Common questions

Is AI Storefront Readiness Grader safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 23 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Paid Agent APIs

Pay-per-call MCP APIs for AI agents. Every call is settled in USDC via the x402 protocol on Base — no accounts, no API keys, no subscriptions. Payment is the auth: your agent pays per call and gets the result.

Service	What it does	MCP tool	Price	Status

GEO Audit	Scores any URL's visibility to AI search engines (ChatGPT, Perplexity, Claude, Google AI Overviews) across 20 weighted checks and returns concrete fixes. Free tier: `audit_geo_lite`, rate-limited	`audit_geo`	$1.50 / call	✅ LIVE

Live endpoints

Service	MCP endpoint	HTTP endpoint
Storefront Grader	`POST https://grader-al6bxcngia-ue.a.run.app/mcp`	`POST https://grader-al6bxcngia-ue.a.run.app/grade`
GEO Audit	`POST https://geo-al6bxcngia-ue.a.run.app/mcp`	`POST https://geo-al6bxcngia-ue.a.run.app/geo` · free: `POST /geo-lite`

Both take { "url": "https://your-site.example" }. Source for every service lives in this repo (grader/, geo/, a11y/).

Add either live service to any MCP client as a remote server:

"mcpServers": { "storefront-grader": { "url": "https://grader-al6bxcngia-ue.a.run.app/mcp" }, "geo-audit": { "url": "https://geo-al6bxcngia-ue.a.run.app/mcp" } } }

For agents: how payment works

Call the tool or endpoint without payment → you get an HTTP 402 with the full payment requirements (amount, network, pay-to address).
Pay in USDC on Base mainnet (eip155:8453) with any x402 client (@x402/fetch, the x402 Python package, CDP or PayAI wrappers) and retry with the payment proof.
The call runs and returns the result. No signup, no key management, no invoice.

Discovery documents (/.well-known/x402):

https://grader-al6bxcngia-ue.a.run.app/.well-known/x402
https://geo-al6bxcngia-ue.a.run.app/.well-known/x402

Both services also declare the Bazaar discovery extension (extensions.bazaar) in their 402 responses, so catalog crawlers can index the paid routes from the 402 alone.

Payment terms: x402 exact scheme · asset USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) · pay to 0xd702C8A8Ee30F6950A2a663010d12FC195D5348e · facilitator PayAI (https://facilitator.payai.network), with Coinbase CDP facilitator support built in.
