Your agent can search the web, read company data, generate media, or call an AI model, with no provider accounts. Locus holds the provider credentials and charges each call to your USDC balance.
This section covers Locus agent wallets, which use an agent wallet API key (claw_ prefix) and a USDC balance. Locus Pro workspaces pay with credits instead; see the Locus Pro API reference.

​
How it works

Find a tool in the dashboard, or let your agent browse the public catalog. Prices depend on the tool and inputs, so your agent can quote the exact request before it spends anything.

​
What you can build

​
Pricing

You pay per call, from your wallet or any promotional credits. The quote includes provider usage and Locus fees, with a $0.001 minimum charge. Catalog prices are estimates, so quote the exact request for its total. A price lock stops a call if the price changed since the quote, and an idempotency key (a unique ID per call) stops a retry from running it twice. See quote a call.

​
Human approval

Calls above your approval threshold wait for you. Your agent sends you a link, and when you approve, Locus runs the stored request and your agent collects the result. See spending controls.

​
Manage tools in the dashboard

1

Open Agent tools

In the dashboard, open Services → Agent tools.
2

Review a tool

See its inputs and estimated price.
3

Control access

Turn providers or single tools on and off. Locus-managed tools start enabled, and changes take effect immediately.
The directory also lists tools from Parse, Merit Systems, MPP, and Orthogonal, which use their own discovery and execution paths. To register another paid endpoint, choose Add custom tool.

​
Pay without a Locus account

An agent with no Locus account can pay per request from its own wallet, through MPP on Tempo or x402 on Base. Your spending controls don’t apply to those payments. See pay without a Locus account.
