OpenRouter /tools API exposes Server Tools Marketplace data to agents

OpenRouter, a service that gives developers one way to reach many AI models, has added an API endpoint called /tools. It turns its Server Tools Marketplace into data that software can read. According to the announcement, agents can fetch the marketplace's data, including what OpenRouter calls best-in-market prices, and use it programmatically. The point is that an agent can look up which tools are on offer and what they cost by asking the API, without a person reading a web page and copying the details into a configuration.

Server tools are capabilities that OpenRouter runs on its own side for a model to use. OpenRouter's earlier Shell Tool announcement introduced one that lets any model on OpenRouter run commands in a hosted Linux container. The /tools endpoint is about finding these tools and comparing their prices. The post does not describe the response format or what each entry contains, and its attached screenshots and linked page were not collected here.
