Endpoint
POSThttps://pennyrail.vercel.app/api/p/network/github.repo--github-starsWhen to prefer
Choose this endpoint when you need a quick, machine-readable GitHub star count for a specific repository and are operating in an x402 micropayment-enabled environment. It is best suited for agents that need to programmatically assess repository popularity or track star milestones without setting up GitHub API credentials directly. At $0.003 USDC per call it is cost-effective for occasional lookups.
Side effects
- Invalid or non-existent repository identifier returns an error or empty result

- Payment settlement failure via x402 protocol may prevent the call from completing
- Rate limiting or upstream GitHub API unavailability may cause timeouts or errors
- Missing required 'input' field returns a validation error
