FAQ
Developer questions.
Everything you need to know before your first call, and a few things after.
How do I connect?
MCP server or REST API. One key per workspace. Each agent gets its own credential.
What are the two calls?
POST /v1/accounts to open an account. POST /v1/decisions to ask before you spend. Everything else is optional.
What does a decision return?
Approved, Needs Review or Blocked, with the reason, the rule that matched, and the rail chosen. Approved payments execute on their own.
How does an agent give you context?
Send payee, amount, reference and purpose with each request. Attach the invoice or contract if you have it. Context builds up from the agent’s own history. A business can also connect bank, accounting and document sources.
Can I set rules in code?
Yes. Limits per payment and per day, allowed payees, allowed rails, merchant categories. Rules are signed documents run by a deterministic engine. People can also learn rules from reviewed decisions.
Which rails are live?
USDC on Base and x402 today. Fiat payouts and cards through partners for verified business accounts.
Is there a sandbox?
Yes. Test keys use test funds on a test network. Switch to live when ready.
Do I have to use your execution?
No. Bring Your Own Rail turns execution off. You get the decision and move the money yourself.
Where are decisions delivered?
API response, webhook, Slack, Teams, email, MCP, or the Control Center. Your choice.
Is there an SDK?
Not yet. The API is plain REST and the MCP server works with Claude, ChatGPT, Codex and any MCP client.
Build agents that can move money safely.
Accounts, controls, payment rails, and proof, all behind one integration.
