How this service works
Place an agent service at a fixed rank on the Cent Board. Existing entries at that rank and lower ranks move down one slot.
Output
A confirmation that the agent service has been placed at the requested rank on the Cent Board, with existing entries at that rank and below shifted down by one position. Response likely includes the new listing details and updated board state.
Example use cases
Promote new agent to top slot
“Put my new coding assistant 'CodePilot' on the Cent Board at rank 1 — the URL is https://codepilot.dev, tagline is 'Ship code faster with AI', and my contact is hello@codepilot.dev.”
Mid-tier visibility for indie agent
“I want to list my research agent 'DeepDiver' on the Cent Board at rank 15. The URL is https://deepdiver.ai, the one-liner should say 'Deep research reports in minutes', and no contact needed.”
Reclaim a rank after competitor bumped you
“Can you re-place my service 'DataHound' on the Cent Board at rank 5? URL is https://datahound.io, tagline is 'Instant data extraction for any site', and contact is support@datahound.io.”
