Three ways to use the catalog

Call APIs directly

Use tools from your own code over HTTPS with standard credentials. No agent and no MCP client required — just the catalog, documented prices, and a balance.

Browse the agent tool catalog →Read the quickstart →

Connect an existing agent

Point a supported MCP client at one hosted server URL, approve access with browser OAuth, and let the agent discover and pay for permitted tools per call.

Explore paid MCP tools →Read the agent connection guide →

For agent platforms

Embed tools and billing

Ship the catalog inside your product with per-customer metering, markup, and billing collection — the primary commercial path for companies building agent products.

For companies building agent products

Locus Pro Enterprise gives your platform the catalog plus the commercial controls around it. Every capability below is documented product behavior — see how platform billing and metering work.

  • Catalog access

    Offer an opt-in set of catalog services to your users at base prices you mark up, documented in the catalog reference.

    Read the catalog docs →

  • Customer attribution

    Your server passes the customer or workspace context with each request, carried through authorization, execution, and the usage record.

    See attribution on the enterprise page →

  • Call-level metering

    Every tool call burns prepaid credits at its effective price and returns the charge with the remaining balance for usage review.

    How metered billing works →

  • Pricing and markup

    Personal accounts pay displayed tool prices; enterprise production carries a marginal platform fee with 100% of configured markup yours.

    Read the pricing math →

  • Spend controls

    Scope credentials to tool bundles, apply per-user balances and limits, and keep tenant secrets on trusted servers.

    Read authentication and scopes →

  • Billing collection

    Bill through your own flow or use Locus-hosted checkout for end-user top-ups, with eligible margin accruing for payout.

Tools agents use vs. tools for building agents

This page lists tools agents use: paid APIs an agent calls while doing work — searching, enriching, transcribing, generating, verifying. If you are looking for agent frameworks, model SDKs, or scaffolding to construct an agent, those are development-time choices; start with the developer overview and the framework integration guide.
