Wallet that works across 6 chains.
One session wallet holds USDC on Solana, Base, Polygon, Arbitrum, Optimism, and Avalanche. When an API wants payment, it pays from whichever chain the seller accepts. You fund it once.

Your agent can pay for APIs now.
OpenDexter lets your AI agent pay for APIs on its own. Install it into Claude Code or Cursor and it can find paid endpoints, check what they cost, and pay for them in USDC without bothering you.

§ 02Install
Install it.
Two options. Run it locally with your own wallet, or connect to the hosted version and skip the setup.
Run it locally.
One command creates a wallet on your machine and installs OpenDexter into Claude Code, Cursor, Codex, Windsurf, Gemini CLI, or VS Code. You hold the keys.

What it does
Seven tools, and what they do.
Search in plain English.
Ask for "ETH price feed" or "generate an image" and get back real endpoints ranked by what works. The ranker handles synonyms and intent on its own. No need to pick a chain or category first.
See what something costs before you buy.
Probe any endpoint for its price per chain, auth mode, and input/output schema. Nothing gets signed, nothing gets paid. Your agent can plan before it spends.
Pay and call in one step.
Hand it a URL. It handles the 402, signs the payment, retries the request, and gives you back the response plus a settlement receipt. USDC only. x402_pay is the same tool under a different name.
Sign into identity-gated APIs.
Some APIs want a wallet signature instead of money. Sign-In-With-X handles that in the same surface, without you handing over a private key or running an OAuth flow.
Set a spend cap.
Cap what an individual call can cost. The agent respects the cap across every tool. If a resource asks for more, the call is refused before signing.
What’s behind it
How we keep the list honest.
Real-money verification.
Every listed API is tested every 15 minutes by actually paying for it. A frontier model rates the response. Bad responses push the score down. Below the floor, the API gets dropped from the public feed.
Auto-discovery.
Any seller whose endpoint gets paid through the Dexter facilitator is added to the catalog automatically. No signup, no form, no curator. If people are paying for it, we know about it.
§ 03Catalog
How the catalog gets built.
Every API that gets paid through the Dexter facilitator gets added automatically. We test each one every 15 minutes by actually paying for it, then rate the response. Bad ones drop off. That’s the list.
Most x402 directories either show every endpoint they can find, or pick favorites and bury the rest. We don’t do either. The intake is automatic, the tests are automatic, and the ranking is public.
Right now we’re tracking 21,734 endpoints and about 834 of them pass the tests. The rest either broke, went dead, or scored too low.
