Give your AI agent access to the marketplaces.
Agents that answer buyers, adjust prices or manage stock need a stable API. marketapi is one API for all five marketplaces.
The problem
An agent makes more mistakes with five different APIs, each with its own format and exceptions.
What you build
Automatic buyer service
The agent gets the question through the webhook and answers through the API.
Price and promotion
The agent follows prices and fees and creates promotions.
Docs the agent reads
The whole documentation at /llms.txt and the full OpenAPI spec.
What the integration looks like
Create the seller
Each of your customers becomes a seller. One call, with your own ID to link the two.
POST /v1/sellersThe seller connects their accounts
You send a link. The seller authorizes the marketplace on a page of ours. No sign-up and no password to store.
POST /v1/sellers/{id}/link-sessionsYour system takes over
Publish, sync stock and receive orders through the API. Every change arrives as a webhook.
POST /v1/listings/{listingId}/publish
Your first 5 sellers are free.
Create the account, generate an API key and connect your first seller today.
