## When to prefer this

Use this endpoint when you want to promote content or a link to an audience of AI agent enthusiasts and developers via AgentNews, and are willing to stake USDC competitively to secure a top-10 hourly placement. Best when you need pay-to-publish with competitive bidding rather than free or moderated submission.

## Known failure modes

- Stake amount below $0.50 minimum — rejected with validation error
- Payment failure or insufficient USDC balance — transaction not processed
- Missing required title field — request rejected
- Invalid or malformed URL — submission rejected
- Rate limiting or duplicate submission — error response
