HitPay for AI agents

HitPay provides payment processing, invoicing, and recurring billing for merchants, covering charges, orders, and payouts. Finance teams use it to track this without reconciling numbers by hand at month end. 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.

04 · AUTH AND DATA

How HitPay connects.

Users add their HitPay 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 HitPay connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

HitPay and Arc0, answered.

Q01

Can I use HitPay with Claude, ChatGPT or Cursor?

Yes. Connect HitPay 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 HitPay actions you allow.

Q02

How do users connect HitPay?

Users add their HitPay 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.

Q03

Which HitPay actions can my agent take?

15 in total: 15 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in HitPay?

Yes. Allow read actions and deny writes in the HitPay policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call HitPay too?

Yes. The same HitPay connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
