Give your agents access to search, scraping, enrichment, market data, inference, media, and more through one catalog. Enable the tools your product needs; Locus handles provider access and per-call billing. Open Agent tools in your enterprise workspace to browse tools, see prices, and manage access. Self-serve accounts use Tools.

​
Find the right tool

1

Search the catalog

Search by the task or provider in Agent tools.
2

Review the endpoint

Check its inputs, price, and availability.
3

Enable access

Enable the endpoints your agent needs. Ordinary provider endpoints start disabled; some built-in Recipes are system-managed.
Use a direct tool when a specific provider, dataset, or operation matters. Use a Recipe when you want a complete outcome such as an enriched record or a cited research answer. The directory snapshot covers 3,811 services and 15,977 endpoints. Availability and prices can change, so use your workspace’s live catalog when configuring an integration.

​
Control access and pricing

Enable an endpoint or a whole provider. For customer-billed calls, set a percentage markup, a flat markup, or both. Pricing falls back from endpoint settings to provider settings to your workspace default. For example, enable a search tool and add a 25% markup:
Pooled calls charge your workspace the base price. Markup applies when the call charges an end-user balance. See Credits and pricing for examples. Execution requires a tool to be enabled, currently available, and permitted by the calling credential. The agent can inspect access through its connection before making a call.

​
Read the live catalog

Use a tenant secret key to get the workspace’s current providers, endpoints, enablement, and effective prices:
The response includes each endpoint’s slug, availability, and pricing. Dynamic prices depend on request inputs, measured usage, or an external quote. For management interfaces, use POST /api/credits/catalog/search to find entries including disabled tools. For agent execution, use POST /api/credits/tools/search or MCP discovery.

​
Show customers their tools

Use GET /api/credits/me/catalog with an end-user token to show that customer’s available tools and final prices. It applies workspace enablement and the user’s access policy while keeping your base cost and margin private. This is useful when your app lets customers browse available capabilities before spending credits. The API reference covers filtering, pagination, and response fields.

​
Understand variable prices

​
Response-priced endpoints

Some tools reserve a maximum before execution, then settle against measured usage and release the unused amount. Your markup applies to the measured base. See response-priced endpoints.

​
Live-quoted endpoints

Some external services show Priced live per call. Their price comes from the service at execution time. Ask the agent to inspect the current quote and set a hard max_charge_credits ceiling before running them. For x402 services, MCP estimate_cost supports a no-payment quote with preflight_external_quote: true. If a quote exceeds the execution ceiling, Locus declines the call without charging. Agents discover the current request format through each endpoint’s schema. See the API reference for direct-call formats.

​
Give an agent workspace-specific docs

Locus generates Markdown for the tools your workspace has enabled:
Omit provider for the enabled catalog index. These authenticated docs include base costs and markup, so keep them in trusted server workflows. Never expose your secret key to an agent runtime or end user.

​
Add your own service

Custom APIs bring your HTTP services into the same discovery and access controls. Account integrations such as Gmail or Slack OAuth connections remain with your existing integration platform.

Connect an agent

Let agents discover and call your enabled tools.

Set customer pricing

Set a default markup and override it where needed.
