I can't wait to see test track's evolution.

What is the countdown for the missions?

Agents at Work: Building Voice Interfaces for AI Agents

I interviewed Tom Shapland, product manager at LiveKit, for the Agents at Work podcast.We talked about how LiveKit’s open-source infrastructure became the audio transport layer for ChatGPT’s voice mode, and what it takes to build reliable, production-grade voice agents.Topics include: – Voice vs. text pipelines (cascade vs audio-in/out) – Turn detection and latency problems – Ambient computing...

Yes, but there is a "free lunch" problem. I can run a script that hits your page costing you X at a fraction of the cost for me (the user)

The other obvious solution is a "web of trust" where Cloudflare just tells you "this request goes in, this one goes out".

I think the paying approach is superior (after all you make money out of people using your service) but Cloudflare is a straight forward/simpler one.

I've talked with tons of publishers and all say the same thing:

"Hey, we'd happily give these companies clean data if they just paid us instead of building these scrapers."

I think there is a psychological aspect that made micropayments never work for humans but machines may be better suited for it.

There's a real economic problem here: when someone scrapes your site, you're literally paying for them to use your stuff. That's messed up (and not sustainable)

It seems like a good fit for micropayments. They never took off with people but machines may be better suited for them.

SaaS is not dead: building for AI Agents

I keep seeing people claiming that SaaS is dead, they are wrong. In fact, SaaS isn’t dying, it’s evolving. The users are changing though. AI agents are becoming a new kind of user, and SaaS volumes will skyrocket because of it.As LLMs improve, AI agents are becoming increasingly capable of reasoning and executing complex tasks. While agents might be brilliant at reasoning, they can’t currently...

Machine-Friendly Payments with L402

One of the biggest blockers for AI agents is the inability to pay for services programmatically.We build an end-to-end demo for AI agents showing how to solve that. It has two components:- A simple API that provides stock price information, paywalled with the L402 protocol- An AI Agent that autonomously pay for and consume the API, performing complex tasks like comparing stock pricesIn just a...

With a new protocol, AI agents can now autonomously discover and integrate with services in real time. No prior setup or manual intervention is required, making it easier for agents to access and use third-party tools, services, and APIs. This development marks a key step toward a more seamless, machine-friendly digital ecosystem.
> I don't think creators or consumers want to use Bitcoin. That's right.

> Consumers also want to pay in local currency. Taproot Assets will bridge this.

In Fewsats for example the user prices the services and gets the payouts in $ by default.

Wow, what a surprise to see L402 on HN today!

We're the team behind Fewsats, a serverless platform that allows developers to easily deploy and paywall their applications using the L402 protocol with just a few clicks. Currently, we support STaaS (files) and DaaS (databases, in beta), with plans to expand to video streaming, APIs (FaaS), and more.

We would love to see L402 ecosystem. To that end, we've released some handy open-source tools, including the L402 Python library (just `pip install l402` or check the tutorial from the L402.org page) and Pillbox, an L402 credential manager.

Please don't hesitate to reach out if you have any questions about Fewsats or L402 in general. We'd love to chat!

Re:L402: Internet-Native Paywalls on Tuesday July 02, 2024 @12:35PM (#40858235)
The L402 protocol has a new dedicated page aimed at spreading awareness about the protocol and showcasing related tools and services that utilize it.

Built on top of the `HTTP 402 Payment Required` error, L402 brings built-in payments to the HTTP level.

The protocol defines a clear flow for servers and clients to process and verify payments automatically, making it a great solution for machine-to-machine interactions.

L402 is currently being used in production by companies such as Lightning Labs, where it was developed, fewsats.com or sulu.sh.

Addressing some misconceptions from previous Hacker News posts about L402, I would like to clarify two key points:

- L402 is not limited to micropayments. While the Lightning Network supports micropayments, L402 accommodates a wide range of payment types (one time, subscriptions, etc) and amounts, making it suitable for various use cases.

- The L402 flow is designed to be credential and payment agnostic. Although the current specification utilizes macaroons and Lightning invoices, any type of credential that can be linked to a challenge, and any challenge that delivers a proof of completion, can be used. This flexibility allows for the use of various mechanisms, from proof of work to Stripe returning the preimage of a hash.

At Fewsats, we are building a serverless platform that leverages the L402 protocol for built-in payments. However, we would love to see the ecosystem expand and flourish in various directions, with more developers and companies building upon this tech!
