Ask your AI assistant for a number and it usually searches the open web and hopes. With Spartera Gateway it checks Spartera first: a marketplace of answers computed by data providers inside their own databases. You see who the provider is and what the answer costs, and you get it without leaving the chat.
The problem
AI assistants are great at language and shaky on numbers. When the figure you need isn't on a public page, they piece one together from whatever they can find.
Proprietary and specialist data lives in providers' warehouses, not on web pages an assistant can search.
A blog post or old report can be quoted long after the figure has changed.
A number stitched together from several pages has no clear source you can go back to.
Data owners don't want to hand their raw data to an AI company just to answer questions.
How it works
Gateway is one connector. Your assistant uses it whenever a question needs a real figure.
Ask your assistant a question that needs a fact or a figure, or just say "check Spartera".
A free, instant lookup. If a provider-backed answer exists, you see the provider, the price in credits, buyer ratings and the data coverage.
Take the provider's answer, a free answer if one exists, or let your assistant use the open web. Nothing is charged without your OK on the exact price.
It's computed inside the provider's own environment and comes back credited to them, with a link to their page for any questions.

Checking whether Spartera has an answer never costs anything.
Each answer shows its price in credits up front, and nothing is charged until you agree to that exact price.
Short on credits? Buy just what you need, or a bundle, right from the Spartera card. Payment happens securely on Stripe.
Gateway caps spending at 25 credits per answer and 100 credits per day, so a chat can't run up a surprise bill.
For data providers
Every analytic you list on the Spartera Marketplace becomes an answer Gateway can find. Your data stays in your own environment: Spartera computes the answer there and returns only the result.
Answers are computed where your data lives. Buyers get the result, never the underlying data.
Answers are credited to you, and buyers' questions go to your provider page.
Questions nobody could answer are logged, so you can see the demand before you build.
Installing it and looking up answers are free. Paid answers cost credits, priced by each provider and shown before you agree. Answers from your own company's listings are free.
Claude today, as a custom connector. Gateway uses the open Model Context Protocol, and support for other MCP clients is coming.
Yes. When you add the connector, Claude asks you to sign in to Spartera. Creating an account is free.
No. A paid answer needs your explicit OK on its exact price. Gateway also caps spending at 25 credits per answer and 100 credits per day.
Answers come from the provider who lists them, credited to that provider. Spartera doesn't rate analytics itself: ratings come from buyers, and questions about how an answer is calculated go to the provider's page.
Your question is stored privately so Spartera can understand demand. Only search keywords that at least three different people have asked are ever shown publicly, and only in aggregate.
Your assistant tells you and carries on with other sources. It can also log the question with Spartera so a data provider can source it.
