Payhip for AI agents
Payhip is an ecommerce platform for selling digital products, memberships, and physical goods directly to an audience. Creators use it to run their own storefront without a marketplace middleman. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

How Payhip connects.
Users add their Payhip api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
The same Payhip connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Payhip from any agent.

Payhip and Arc0, answered.
Can I use Payhip with Claude, ChatGPT or Cursor?
Yes. Connect Payhip to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Payhip actions you allow.
How do users connect Payhip?
Users add their Payhip api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
Which Payhip actions can my agent take?
9 in total: 2 read, 6 write and 1 destructive, such as “create Coupon”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in Payhip?
Yes. Actions like “delete Coupon” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.
Can my own backend call Payhip too?
Yes. The same Payhip connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Payhip into your agent.
Your users connect Payhip once, under your brand. Your agent gets 9 actions behind your policies, with every call on the record.
