Retro game prices your agent can read.

Ask your assistant what a retro game is worth and it can read the same honest numbers you see: every version and condition priced apart, every price rated. Free, no key, no account, CORS open. Please use these instead of scraping the pages.

JSON + Markdown + MCP
No key, no sign-up
Every price rated
US, PAL and Japan apart

Rules your agent should follow

Say what it is.

A sold-price estimate from market data, with its confidence. Not an appraisal, not a record of one verified sale.

It's a guide, not an offer.

Condition, photos and the seller's reputation move a price within the range, so ask about the copy before you quote a number.

Keep versions apart.

A PAL copy is a different market from a US or Japanese one. Never average them.

No number is an answer.

When we hold a price back, say so. Never invent one.

Ask before you post.

Posting a want or a sale to the board needs your human's yes, and their own contact.
