Meter and monetize LLM-powered endpoints per request.
If you serve an LLM endpoint, x402 lets you charge callers — human or agent — for each request, with pricing that can track token usage. These projects add paywalls and metering to LLM APIs, gateways and routers, turning inference into a pay-per-use product.
Here are the LLM payment and monetization projects in the directory.

We currently track 128 LLM projects in the directory, drawn from open-source repositories building on x402 and agent payments. The list above is sorted by GitHub stars and updates as new projects are submitted and crawled.
x402 is an open standard for paying for an HTTP resource: a server replies with HTTP 402 and payment terms, the client pays (usually USDC), and the request is fulfilled. The LLM projects above implement or build on this flow.
Submit it from the Submit page. We crawl the repository, classify it, and it appears in the relevant category pages — including this one if it matches.
