Lago. Lago is a billing platform that provides API access for pushing customer information and metrics (events) from applications to a billing system.

Useautumn. Autumn is a control plane for usage-based pricing - one layer for billing, ledgering and entitlements that moves pricing from code into config, enabling companies to change plans and sell custom contracts 10x faster.

Where Lago is ahead

Lago passes mcp discoverable, and Useautumn does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: authentication documented. Useautumn misses it.

And on adopt, mcp integration available. Useautumn misses it.

Finally, on operate, agent compatibility verified. Useautumn misses it.

Where Useautumn is ahead

It also holds understand: pricing understandable. Lago misses it.

And on adopt, self-service signup, agent-compatible signup flow, free trial or free allowance and cli available. Lago misses those.

Finally, on operate, observable execution. Lago misses it.

What neither does

Both fail structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, fast time to first request, copyable quickstart, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
