Greenlight API Check
Greenlight API Check helps developers verify AI API relay endpoints before integration or recharge.
01
Overview
Greenlight API Check is a developer utility for testing OpenAI-compatible, Claude/Anthropic-compatible, and Gemini-compatible API relay endpoints before users rely on them. It checks endpoint availability, authentication, latency, model consistency, streaming behavior, error structure, billing signals, and key-safety boundaries, then generates a shareable report for preflight review. It is not an API relay provider, key seller, recharge service, or upstream channel.
