In collaboration with Google Cloud, we're building the open source real-time payment infrastructure for AI agents so they can discover and pay per call for any API.
The agent native angle is what stands out most .Feels like this isn't just a dev tool but infrastructure for autonomous systems.
Pay-per-request, no API keys, agent-native — this is one of those primitives that quietly unlocks a category of products that just couldn't ship before. The thing I'm most curious about is the failure mode: what happens when an agent gets into a feedback loop and burns through 10,000 micro-payments in a minute? I run a small AI alerts product around prediction markets called PolyMind, and the autonomous-decisions-on-noisy-signals problem is brutal even at fixed cost per call. With pay-per-request you've added a real money knob to the loop. Are you exposing budget caps / circuit breakers at the agent level, or leaving that to the agent runtime? Cool launch either way — congrats.
Coolest thing is its completely cli based and will bring ease to me on top of the AI agents I use.
super cool ship ♥️
Love this direction - One command line to let your agents pay for any API. No accounts. No keys. No subscriptions needed.
Thanks @fmerian! Hey everyone, I'm Ludo, maker of pay.sh 👋
In collaboration with Google Cloud, we're building the open source real-time payment infrastructure for AI agents so they can discover and pay per call for any API.
We are replacing sign-up pages, API tokens and subscription management with a new intuitive tech stack designed for agents to pay for services and goods.
It will be a long journey, and today we're super excited to ship the following:
Agent Gateway for Google Cloud: a hosted proxy that allows agents to access major APIs including Gemini, Maps, BigQuery public datasets, and twelve others APIs.
pay: a command-line tool for consuming this new generation of API endpoints. If you're running some APIs, pay can also be deployed as a proxy. Local first, MIT Licensed.
pay-skills: a catalog of high quality APIs, community-driven. Think `brew` for OpenAPI specs that can charge agents (PAY.md). MIT Licensed, PRs welcomed. Curated and monitored.
pay.sh is built on top of strong standards (x402, MPP) involving players such as Cloudflare, Stripe, Solana Foundation, Coinbase and many others who understand this direction is inevitable.
To give it a try: brew install pay. Let us know what APIs you want added to pay.sh, or any kind of feedback.
I'll stay on top of your comments!

Who hunted pay.sh?
pay.sh was hunted by fmerian. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Love seeing open source infrastructure being built for this layer instead of locking it into a single platform ecosystem.
