```bash
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \

  -d '{"method":"central.sonatype.com/get_latest_version","input":{"library":"jackson databind"}}'
```

From an AI agent connected to the Fous MCP server: its `run` with the same method and input. To connect one, give it `set up https://fous.com/SKILL.md`.

## Ask your agent

- What's the newest release of com.fasterxml.jackson.core:jackson-databind? I need the Gradle dependency line too.
- Check sonatype.com for the current version of Apache Commons Lang 3 and when it was released
- I'm updating my pom.xml — give me the latest Maven snippet for org.slf4j:slf4j-api
- How many versions of Lombok have been published to Maven Central, and which one is the most recent?
- Look up spring-boot-starter-web on sonatype.com and tell me its latest version, release date, and the Maven Central link
