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.<p>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 interact with most third-party services. Right now, the go-to solution is function calling, but it’s still really limited. On top of many services lacking an API some flows are highly integrated with the browser/expecting a human in the driver's seat.<p>- Accounts: 2FA, captchas, links to emails, oauth....<p>- Payments: anti bot tech built-in (for the last 25 years we really did not want bots to pay!), adhoc flows in the browser...<p>I have been thinking for a while how a blueprint for a SaaS designed to AI Agents would look like, and then I went and build it!<p>I wanted a good first fit, with a simple and small API, useful, something that I hate to do and one time purchases. The result was a Domain Registrar for AI Agents<p>Here’s how it works:<p>- Agents don’t register accounts. They authenticate using public key cryptography. Simple, secure, and no humans required.<p>- Browser-less payments. Agents can programmatically pay via credit cards, Lightning Network, or stablecoins. Some flows are fully automated, no browser needed.<p>- Python-first integration. We’ve created the package `sherlock-domains` package with agents in mind. I that a `.as_tools()` method compatible with OpenAI, Anthropic, Ollama, etc., returning all the details agents need to interact via function calling.<p>- Human-friendly fallback. If a user wants to manage domains manually, they can log in, review DNS settings, or even fix issues by sending a chat message with a screenshot of the DNS request. The changes “magically” happen.<p>This isn’t just about a domain registrar but more about how SaaS will evolve in the next months to cater to a new set of users, AI Agents.<p>I believe the opportunities for agent-first services are huge. Eager to get your feedback!
