Questions about the API, integration help, partnership ideas, or just feedback — send us a note. We read every message.
Before you write
A lot of common questions are already answered in the API docs and on the For Agents page (tool definitions for every major framework). For background on how payment works, see Why x402.
Protocol questions vs Skim questions
For questions about the x402 protocol itself (spec, facilitators, SDKs in other languages), the canonical source is x402.org. For questions specifically about Skim — the reader, pricing, uptime, integrations — email is the right place.
Reporting an issue
If something looks broken, please include the URL you were trying to read, the time the call was made (with timezone), and any transaction hash if a payment was involved. That information lets us trace the request quickly and reply with something useful.
