Every agent, its own account.
Spin up an isolated sub-account in one API call. Separate budgets, separate cards, separate audit trails — per agent, per run, per customer.
Sub-accounts, cards, and payments — built for agents, ready to drop into OpenClaw, Hermes, Claude, LangChain, and more.
Foundry is a fintech, not an FDIC-insured bank. Funds are held non-custodially via Crossmint, our blockchain/fiat partner.
Works with the stack you already use
A full banking stack built from scratch for AI agents — not duct-taped onto products built for humans.
Spin up an isolated sub-account in one API call. Separate budgets, separate cards, separate audit trails — per agent, per run, per customer.
Issue a card in a line of code. Spend limits that bite, not blink. Lock any card instantly from the API.
Set the boundary once. Your agents can't cross it — even if they wanted to. ALLOW, DENY, LIMIT, REQUIRE at the network level.
Or your customers. Same flow. Agents read, agents sign, agents get paid. Created → Sent → Viewed → Paid.
Every major rail, one API. ACH, wire, RTP, card, and Tempo — on-chain when you need instant.
Automate billing, subscriptions, and invoice collection. Your agents can run a business — give them the tools.
See where the money goes before it goes somewhere you didn't expect. Per-agent, per-category, per-day.
Park treasury in auto-yielding vaults. Earn on idle agent balances, withdraw instantly when spend spikes.
Drop the SDK into your agent. One install. Real banking in two minutes. Works with OpenClaw, Hermes, Claude, LangChain, and every other framework your team ships on.
Drop this into your agent.
