Status page showed 80.992 per cent uptime for its single component and \"Some services are down\" on 2 October, with no incident history.\n\n**W\u0026B Weave.** The Service API at trace.wandb.ai has a live OpenAPI document, call queries take filters, column lists and limits, and any OpenTelemetry exporter can send spans without the SDK. 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### HoneyHive\n\n1. Give the agent a read-only `hh_ro_` key for analysis and a separate `hh_ingst_` key for sending traces\n2. Treat a 404 as possibly a bad, revoked or expired key before assuming the record is missing\n3. Set `limit` on `POST /v1/events/search`. The default is 1,000 rows\n4. Use the CLI (`brew tap honeyhiveai/tap \u0026\u0026 brew install honeyhive`) from a coding agent. It maps one command to each API endpoint\n5. Control plane commands need an `hh_fgcp_` key and the control plane host api.cp.us.honeyhive.ai\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, HoneyHive or W\u0026B Weave?\n\nW\u0026B Weave scores 66.7 (B) on agent readiness against HoneyHive's 55.7 (C), and leads in 6 of 7 scored categories. HoneyHive leads on schema \u0026 documentation.\n\n### Do HoneyHive and W\u0026B Weave need an API key?\n\nBoth need an API key.\n\n### Can an agent call HoneyHive and W\u0026B Weave without installing anything?\n\nYes. HoneyHive has a hosted endpoint at https://api.dp1.us.honeyhive.ai and W\u0026B Weave at https://trace.wandb.ai.\n\n### Are HoneyHive and W\u0026B Weave open source?\n\nNo open-source release is listed for HoneyHive. 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/honeyhive-vs-wandb-weave.json, and with the fewest tokens: https://www.anchorterminal.com/compare/honeyhive-vs-wandb-weave.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"honeyhive\", \"b\": \"wandb-weave\"}`.
