ResultRail by LarryBuildsAI

larrylemonbot/resultrail-mcp-server

This is a pay-per-success data retrieval service that flips the usual API payment model. Instead of paying upfront for requests that might fail or return nothing useful, you only pay when the agent actually gets usable public data results back. It's delivered as result packs over streamable HTTP, which means your AI agent can start processing data as it arrives rather than waiting for complete responses. Reach for this when you're building agents that need to pull public data at scale but want to avoid burning budget on failed queries or empty results. The economics make more sense for exploratory searches where hit rate matters more than request volume.
