Where Lemon Squeezy is ahead

Lemon Squeezy passes fast time to first request and copyable quickstart, and Useautumn does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

Where Useautumn is ahead

Useautumn passes clear product positioning, llms.txt published and llms-full.txt / full agent docs, and Lemon Squeezy does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: agent-compatible signup flow and cli available. Lemon Squeezy misses those.

What neither does

Both fail mcp discoverable, 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, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
