## When to prefer this

Use this endpoint when you want to programmatically register a new service provider account on the the402.ai agentic marketplace, enabling subsequent service listing and monetization for AI agents. Prefer this over manual registration flows when automating provider setup or integrating into a CI/CD pipeline for deploying AI services.

## Known failure modes

- Duplicate registration attempt returns conflict error if provider already exists
- Missing required provider profile fields returns validation error
- Invalid payment configuration causes onboarding to fail
- Platform quota or eligibility restrictions may reject certain provider types
- Network or payment failure (x402) may result in incomplete registration

## Output
