What is llms.txt?

llms.txt is a plain-text file at the root of the RohoPay documentation that summarizes the entire API in a format optimized for AI language models. It follows the emerging llms.txt standard. Available at: https://docs.rohopay.com/llms.txt

​
Why Use It?

Without context, AI assistants often hallucinate API endpoints, generate wrong authentication patterns, or use incorrect phone formats. By injecting llms.txt into your AI context:
  • Claude, GPT, Gemini, and others know the exact endpoints
  • Phone number formats are accurate per country
  • Idempotency requirements are understood
  • Test cards and test phone numbers are known
  • Error codes are correctly referenced

​
Usage

​
Claude Code (CLAUDE.md)

# Download and add to your project context
curl https://docs.rohopay.com/llms.txt >> CLAUDE.md
Or include it as a URL reference in your CLAUDE.md: 
# CLAUDE.md
@https://docs.rohopay.com/llms.txt

​
Cursor

Add to .cursor/rules/ or include in the system prompt: 
curl https://docs.rohopay.com/llms.txt > .cursor/rules/rohopay.md

​
GitHub Copilot

echo "\n## RohoPay API Context\n" >> .github/copilot-instructions.md
curl https://docs.rohopay.com/llms.txt >> .github/copilot-instructions.md

​
Any LLM via API

import httpx

llms_context = httpx.get("https://docs.rohopay.com/llms.txt").text

Keeping It Fresh

The llms.txt file is updated with every API version release. We recommend fetching it programmatically rather than copying it statically: 
#!/bin/bash
# refresh-llms.sh — run weekly or on deploy
curl -sf https://docs.rohopay.com/llms.txt > rohopay-llms.txt
echo "Updated RohoPay LLM reference: $(wc -l < rohopay-llms.txt) lines"
