And on operate, structured, predictable output. Datadog misses it.

Where Datadog is ahead

Datadog passes clear product positioning and llms.txt published, and Better Stack does not. That is discover, whether an agent can find the product at all without being told it exists.

And on operate, rate-limit behavior predictable. Better Stack misses it.

What neither does

Both fail llms-full.txt / full agent docs, structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, official python sdk, machine-readable errors, retry behavior documented, idempotency support, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
