Get an agent shopping.
Never let an AI buy anything before? Good, you're who this day is for. Pick your agent.
Bitrefill Assistant, on Telegram.
A shop assistant that lives in your chats. Gift cards, phone top-ups and eSIMs. Pay with crypto, card or your Bitrefill balance, right in the chat.
- Open @BitrefillAssistantBot on Telegram and tap Start.
- Connect your Bitrefill account when it asks.
- Say what you want. Confirm. Pay.
Claude, with the Bitrefill connector.
Add Bitrefill to Claude once. From then on, "buy me a gift card" just works.
- Add the Bitrefill connector from Claude's directory.
- Sign in to Bitrefill once to connect your account.
- Ask Claude to find and buy what you need.
- "Find me an eSIM for Lisbon and buy the cheapest one with 5 GB."
- "Get a $50 Amazon gift card for the US store."
ChatGPT, through our MCP server.
Add Bitrefill as a connector in ChatGPT's settings and sign in. Then ChatGPT can shop for you.
- In ChatGPT settings, add a connector with this server URL:
https://api.bitrefill.com/mcp - Sign in to Bitrefill when it asks.
- Ask ChatGPT to buy something.
- "Buy me a €25 Amazon.de gift card and send me the code."
Claude Code, Cursor, OpenClaw, Hermes and the rest.
If your agent reads skills, give it this one line. If it speaks MCP, point it at our server.
- Tell your agent:
Set up bitrefill.com/agents/SKILL.md - Or add the MCP server:
https://api.bitrefill.com/mcp - Sign in to Bitrefill once, then let it shop.
- Claude Code and Cursor each have their own step-by-step page in the setup guides.
Building your own agent? Use the API.
REST API or the MCP server with an API key. Products, invoices and orders, all programmatic.
- Create an API key in your Bitrefill account, under Developers.
- Read the API overview and quickstart.
- Ship an agent that buys real stuff.
- The MCP server also takes an API key:
api.bitrefill.com/mcp/YOUR_API_KEY
Paying with x402, no account? Your agent can still shop. Those orders just don't earn the 10% back, because we have nowhere to send it.
Post the receipt. Not the code.
Your post on X is your entry. There's nothing else to fill in.
- A picture of your Bitrefill receipt (order email or order page) with the order number readable.
- Gift card code and email hidden. Anyone can redeem a code they can read.
- Tag @Bitrefill with #ProofOfSpend, publicly, by Wed 2 Dec, 23:59 UTC. Keep it up until you're paid.
Opens X with @Bitrefill #ProofOfSpend filled in. Add your picture there.

Fair enough.
What is Agent Sunday?
The Sunday between Black Friday and Cyber Monday, 29 Nov 2026, given over to AI agents. You let one do your shopping on Bitrefill. Gift cards, phone top-ups, eSIMs: if we sell it, your agent can buy it.
I've never used an AI agent. Is this for me?
Especially for you. Start with the Bitrefill Assistant on Telegram: it's a chat, so if you can send a message, you can do this.
When exactly?
Sun 29 Nov, 00:00 to 23:59 UTC. The status card at the top shows it in your own time.
Is this a contest? What if the pot runs out?
No draw, no winners. Every valid post gets paid, in the order posts appear, until the €3,000 pot is empty. When it is, we say so here and on @Bitrefill.
Why hide the code and email?
A gift card code is money. Anyone who can read it can spend it. We only need the order number.
I got a VIP card. What now?
Lucky you. Everything for card holders is on its own page: agentsunday.ai/vip.
