Building on Paygentic with LLMs

Leverage LLMs in your Paygentic development process

Large language models (LLMs) can help when you’re building integrations with Paygentic. To make the most of this, we offer a range of resources and guidelines for using LLMs effectively during your development workflow.

Accessing plain text documentation

You can get clean, markdown-formatted versions of all our documentation by appending .md to any doc URL. For example, you can access this page as plain text at /platform/building-with-llms.md.

This format is particularly suited for use with LLMs and AI tooling because:

• Markdown is easier for LLMs to parse compared to HTML or script-heavy pages
• Content hidden behind tabs or conditional UI in the web version is fully exposed in the plain text
• The structured format makes it easier for models to follow document flow and hierarchy

Additionally, we provide a file at /llms.txt that outlines how LLMs and AI tools can fetch these simplified versions. This follows the llmstxt.org standard to improve accessibility for AI agents.

Copy markdown

Want to reuse or analyze the markdown for a page? Select the Copy Page button in the top-right corner to instantly copy the full markdown content to your clipboard.

Claude Code skills

If you use Claude Code, install the Paygentic skills plugin to give Claude built-in knowledge of how Paygentic works. The plugin is open source at paygentic/skills.

The plugin ships two skills that Claude loads automatically when relevant:

Skill	Use it for	Triggers when you say…
explore	Understanding Paygentic — billing model, metering, subscriptions, entitlements	”how does Paygentic metering work”, “what is consumption-based billing”, “how do subscriptions work”
integrate	Writing integration code with the SDK (TypeScript or Python) or the raw REST API	”set up billing”, “send usage events”, “create a customer”, “wire up Paygentic”

Install

In Claude Code, run:

/plugin marketplace add paygentic/skills
/plugin install paygentic@skills

Try it

Open Claude Code in a project where you’re integrating Paygentic and ask:

• “Add Paygentic metering to this Express handler — emit a usage event for every request.”
• “How does Invoice 0 payment gating work? I’m trying to decide if I need it.”
• “Generate a webhook handler that activates a subscription when invoice.paid fires.”

Claude detects the request and loads the appropriate skill automatically — you don’t need to mention the skill by name.
