Obolpay x402 MCP server

Lets your AI look up pay-per-call data services and preview samples for free before any payment.

This is a small helper program that connects your AI assistant to Obolpay, a service that sells premium data one request at a time. It is meant for people who want their AI to check what data is available and see a free sample before deciding anything. Right now the buying part is paused, so think of it as a way to explore and inspect, not to spend.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to an outside service. This one connects your AI to the Obolpay data gateway, so it can ask that gateway what is for sale and show you a free preview. You stay in the chat, and the helper does the talking behind the scenes.

What this MCP server does

You ask your AI something like what data services are available or show me a sample. The AI passes that question to this helper program. The helper talks to the Obolpay gateway over the internet and asks for its list of services and a free preview. The gateway sends back details like the price, the network, and a small sample of the data. Your AI then explains that back to you in plain words.

What you can do with it

List the data services Obolpay offers, with prices and network details
Fetch a free sample of a data service so you can judge its quality
Check a wallet balance and how many calls are left
Verify a signed proof-of-purchase receipt from a past transaction
See the next nonce for a wallet, useful for tracking activity
Request only new items since your last call, to save space in the chat

Try asking your AI

“What data services does Obolpay offer right now?”
“Show me a free preview of the latest service and tell me the price.”
“Check the balance for this wallet address and how many calls are left.”
“Verify this receipt message and signature for me.”

What it gives back to you

You get back plain answers in the chat: a list of services with prices, a small sample of the data, a balance number, or a yes or no on a receipt check. The helper does not dump raw files on you. It hands the details to your AI, which then explains them in normal language.

Before you start

What you need

Python installed on your computer
A Base wallet address with USDC and a little ETH if you ever want to pay (not needed for previews)
The Claude desktop app or another AI tool that supports MCP servers
The private key for that wallet, kept somewhere safe

Good to know

The buying tools are paused and will not spend your money right now, but if you ever add a wallet key, treat it like cash and keep it private.
