What Vellum does that Marqo does not

Vellum passes clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, and Marqo fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.

Why people look for an alternative

Marqo fails clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, fast time to first request, copyable quickstart, cli available, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
