Ask Grok or Claude about comics for sale

You can ask Grok, Claude, or ChatGPT what’s actually for sale on Atomic Avenue â€" live copies, grades, and asking prices â€" without scraping the website. They talk to our catalog over a public connector (the same plug-in format these assistants already use for Gmail, GitHub, and the rest).

No Atomic Avenue account is required. It does not buy anything, message sellers, or see your account. If you want the book, it gives you a link and you check out on Atomic Avenue like always.

Server URL (no trailing slash):
https://atomicavenue.com/api/mcp

This is the Atomic Avenue marketplace catalog. It is not your ComicBase collection. If the assistant asks you to sign in to ComicBase, you pointed it at the wrong URL.

What you can ask

• What’s the cheapest copy of Cages #1 in VF or higher?
• Affordable VG Amazing Spider-Man #129, unrestored
• What’s in stock for Absolute Batman #1 variants under $20?
• Compare copies of X-Men #1 (1991) across sellers
• Titles matching Miles Morales with copies for sale

Say the series and the issue number when you have them. “VF or higher” means Very Fine and better. Prices are asking prices in US dollars, not sold comps, and not guide value.

Grok

1. Open grok.com/connectors.
2. Click New Connector, then Custom.
3. Name it Atomic Avenue.
4. Paste the server URL above. There is nothing to sign in. Save, then ask one of the questions above â€" including from the Grok phone app.

Claude

1. In Claude, open Customize → Connectors (or use this pre-filled add link).
2. Choose Add custom connector.
3. Name: Atomic Avenue
   URL: https://atomicavenue.com/api/mcp
4. Authentication: none. Leave OAuth client ID and secret blank.
5. Save, then ask one of the questions above. Claude Desktop and Claude on your phone pick up the same connectors once they’re on your account.

If a previous attempt failed, delete that connector and add it again with the URL above â€" Claude can keep a broken registration.

ChatGPT

Turn on Developer Mode (Settings → Connectors → Advanced), create a connector, and paste the same URL: https://atomicavenue.com/api/mcp. OpenAI’s public app directory is a separate review process; until we’re listed there, Developer Mode is the path.

What it will not do

• It will not add items to your cart or check out.
• It will not show seller email, address, or phone.
• It will not invent a grade or a price. If it doesn’t have a live listing, it should say so.
• If a copy sold since the last search, it should tell you it’s no longer available.

A few practical notes

Several series can share a name (there is more than one X-Men #1). If the answer looks like the wrong decade, say the year or the publisher.

The catalog is rate-limited so a flood of automated queries can’t knock over the store. Ordinary questions from Grok or Claude are fine. This is not a bulk dump of the warehouse.

Privacy

The connector only sees public for-sale listings â€" the same facts you’d get browsing Atomic Avenue. It does not use your Atomic Avenue password or your ComicBase collection. Our site privacy notice is here: atomicavenue.com/atomic/Privacy.aspx.
