Quick answer
Loomal and Respan Gateway are both strong choices, but they fit different needs. Choose Loomal if you mainly need monetizing a custom mcp server built for ai agent workflows — its edge is no revenue share means developers keep all earnings from their api calls. Choose Respan Gateway if you need managing multi-provider llm traffic for production ai applications — its edge is combines routing, observability, and evals in a single platform reducing tool sprawl. Loomal starts at $0.01 per API call (USDC); Respan Gateway starts at around $49/month based on usage volume.
Features compared
- List any MCP server or API in the open discovery index in about five minutes
- Per-call micropayments starting at $0.01 USDC via the x402 protocol
- Zero platform revenue cut - developers keep 100% of earnings
- Open payment-ready index for AI agents to discover and pay for APIs automatically
- Unified LLM routing across multiple AI providers with a single API endpoint
- Built-in observability including request tracing, latency monitoring, and logging
- Automated evaluations to benchmark and compare model outputs at scale
- Fallback and retry logic to handle provider outages and reduce downtime
Pros & cons
- No revenue share means developers keep all earnings from their API calls
- Extremely low entry price per call at $0.01 USDC encourages broad adoption
- Quick setup allows listing and monetizing an API in approximately five minutes
- USDC-only payments may not suit developers or buyers who prefer traditional fiat billing
- As a newer platform the discovery index may have limited listings and traffic initially
- Combines routing, observability, and evals in a single platform reducing tool sprawl
- Provider-agnostic design makes it easy to swap or mix LLM providers
- Saves engineering time by replacing custom middleware with ready-built infrastructure
- Relatively new platform so documentation and community resources are still maturing
- Advanced evaluation customization may require technical setup not suited for non-developers
