Integration

Sardis integration

Sardis gives AI agents non-custodial stablecoin wallets with spending policies. Create agents and their MPC wallets, read balances, deposits and the ledger, send USDC and other stablecoins (real funds on mainnet chains), set limits, write spending policies in plain language and test payments against them, grant and revoke spending mandates, place and capture holds, review approval requests, group agents under shared budgets, manage webhooks, verify receipts, screen addresses for sanctions and read spending analytics. Not exposed here: the one-call pay route (its live contract names no source wallet), batch transfers, refunds, virtual cards, fiat treasury, on-ramp, off-ramp and bridging, protocol endpoints (AP2, A2A, ACP, x402, MPP), checkout, marketplace, account, API key, billing and admin routes. Authentication is a Sardis API key sent in the X-API-Key header, created in the Sardis dashboard: sk_test_ keys work on test networks, sk_live_ keys move real money.

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in Sardis.Built from the 103 Sardis tools below, on the connection you add once.

What you can do with Sardis

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Wallet, 8 operations

create_walletCreate walletPOSTCreates a non-custodial MPC wallet for an agent (agent_id required), with a per-transaction and a total spending limit (100.00 and 1000.00 by default). Returns the wallet with its addresses.
delete_walletDelete walletDELETEDeletes a wallet by id. The vendor does not document what happens to a balance left on it, so empty the wallet first.
freeze_walletFreeze walletPOSTFreezes a wallet so it cannot send any transaction until unfreeze_wallet; reason and frozen_by (who froze it) are required. Returns the wallet.
get_agent_walletGet agent walletGETReturns the wallet of an agent, by agent id.
