GoCardless vs Paddle

Paddle scores higher on the AgentReady, 83/100 against 61/100. They differ on 12 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

GoCardless. GoCardless is a payment platform that enables businesses to collect and send payments, minimise failures, and fight fraud.

Paddle. Paddle is a Merchant of Record platform for digital product businesses that manages payments, tax, compliance, and billing across 300+ markets.

Where GoCardless is ahead

GoCardless passes search discoverable, public docs discoverable and llms-full.txt / full agent docs, and Paddle 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. Paddle misses it.

And on adopt, fast time to first request, copyable quickstart, official typescript sdk and official python sdk. Paddle misses those.

Finally, on operate, canonical workflow succeeds, retry behavior documented and observable execution. Paddle misses those.

Where Paddle is ahead

Paddle passes structured api reference, and GoCardless does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
