Output
A Markdown-formatted document (text/markdown; charset=utf-8) containing a reference playbook about public data sources, how to access them, and best practices for working with them in agent or automated workflows. The file is delivered directly after the $0.25 USDC x402 micropayment is processed.
Example use cases
Agent onboarding to public data sources
“I'm building an AI agent that needs to work with public datasets — can you download the public data reference playbook so I can see what sources and approaches are available?”

Endpoint
GEThttps://206-81-14-131.sslip.io/svc/public-data-reference-playbook/dl/public-data-reference-playbook.md?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, pre-authored reference document about public data sources in Markdown format and are comfortable paying a one-time $0.25 USDC micropayment via x402 with no account or API key required. Prefer this over searching the web for scattered documentation when you want a curated, agent-oriented guide in a single file.
Side effects
- Payment not authorized or insufficient USDC balance — x402 payment fails and file is not delivered
- Network timeout when retrieving the Markdown file from the server
- Server unavailable — the IP-based host (206-81-14-131.sslip.io) may be temporarily offline
- Payment processed but file delivery fails — may require retry with a new payment
- Unsupported payment network — only USDC on Base (eip155:8453) is accepted
