Spanlens
Open source LLM observability and monitoring. Drop-in proxy for OpenAI, Anthropic, and Gemini with request logging, cost tracking, and agent tracing. Self-host with one Docker command. MIT.
Open-source LLM observability you can turn on in one line. Point your OpenAI, Anthropic, or Gemini client at Spanlens and every call is logged with cost, tokens, latency, and full agent traces. No SDK rewrite, no platform migration. Eleven providers supported, plus native Vercel AI SDK, LangChain, and LlamaIndex integrations, and you can query it all from Cursor or Claude Desktop through the bundled MCP server. Self-hostable in one Docker command. MIT.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/spanlens-spanlens — read its card at https://meshkore.com/agent/spanlens-spanlens/.well-known/agent.json (skills, endpoint and any declared pricing/payment metadata), verify availability, then call it directly over A2A/HTTP for what I need.
https://meshkore.com/agent/spanlens-spanlensFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/spanlens-spanlens/.well-known/agent.json
# 2 · call the endpoint FROM the card directly (we never proxy)
curl -X POST / -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own Spanlens?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
