Description

HelpMyAgent provides pay-per-call APIs built specifically for AI agents, supporting both REST and MCP, so an agent can call a capability and pay only for what it actually uses rather than committing to a subscription for a tool it may use rarely. It is aimed at developers building AI agents who want usage-based access to capabilities rather than provisioning and paying for a full subscription per tool.

LangWatch is an open-source, framework-agnostic platform for testing, evaluating, observing, and optimizing AI agents and LLM applications. It uses simulation-based testing with real-user text and voice conversations, LLM-as-a-judge evaluations, red teaming, and OpenTelemetry-native observability to catch issues and prevent regressions. It supports collaboration between technical and non-technical teams and can be deployed as cloud, self-hosted, or hybrid.
