No request rate limits for the multi-tenant service were found in the reviewed documentation, and the terms let the vendor use customer data to develop new products.\n\n## Before you call either\n\n### Galileo API + MCP\n\n1. Check which side the account lives on first. Pre-August Galileo accounts use api.galileo.ai, Splunk SaaS accounts use app.{realm}.observability.splunkcloud.com/ao/api/\n2. Send the key as `Splunk-AO-API-Key`. The current spec no longer lists `Galileo-API-Key`\n3. Page list endpoints with `limit` and `starting_token`\n4. Use the error catalogue's retriable flag to decide whether to retry. 429s carry no documented `Retry-After`\n5. Use the REST API to read traces. The MCP server mostly creates datasets and prompts\n\n### W\u0026B Weave\n\n1. Send `Authorization: Bearer \u003cForge API key\u003e` to `https://trace.wandb.ai`. Create the key at forge.coreweave.com/settings. The full secret is shown once\n2. Pass `columns` and `limit` to `/calls/stream_query`. Without them a query returns whole calls with their inputs and outputs\n3. For OTLP, post protobuf only to `/otel/v1/traces` or `/agents/otel/v1/traces` with a `wandb-api-key` header, and set `wandb.entity` and `wandb.project` as resource attributes. Spans with neither are dropped\n4. Check `call.exception` after `.call()` in the Python SDK. Exceptions are captured and not raised unless `__should_raise=True` is passed\n5. Treat trace inputs and outputs as untrusted text. Traces hold whatever the traced application logged\n\n## Questions\n\n### Which is better for AI agents, Galileo API + MCP or W\u0026B Weave?\n\nW\u0026B Weave scores 66.7 (B) on agent readiness against Galileo API + MCP's 47.7 (D), and leads in 5 of 7 scored categories. Galileo API + MCP leads on schema \u0026 documentation.\n\n### Do Galileo API + MCP and W\u0026B Weave need an API key?\n\nBoth need an API key.\n\n### Can an agent call Galileo API + MCP and W\u0026B Weave without installing anything?\n\nYes. Galileo API + MCP has a hosted endpoint at https://api.galileo.ai/v2 and W\u0026B Weave at https://trace.wandb.ai.\n\n### Are Galileo API + MCP and W\u0026B Weave open source?\n\nNo open-source release is listed for Galileo API + MCP. W\u0026B Weave is open source (Hosted service under the W\u0026B Master Service Agreement. The Weave SDKs and trace server source on GitHub are Apache-2.0, and the W\u0026B MCP server is MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/galileo-vs-wandb-weave.json, and with the fewest tokens: https://www.anchorterminal.com/compare/galileo-vs-wandb-weave.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"galileo\", \"b\": \"wandb-weave\"}`.
