What each one is

Permit.io. Permissions for the AI era.

Stripe. Financial infrastructure to grow your revenue.

Where Permit.io is ahead

Permit.io passes llms-full.txt / full agent docs, and Stripe does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, openapi / spec quality, request examples provided, response examples provided and errors and status codes documented. Stripe misses those.

And on adopt, programmatic credential creation. Stripe misses it.

Finally, on operate, machine-readable errors. Stripe misses it.

Where Stripe is ahead

Stripe passes authentication documented, and Permit.io does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: self-service signup and fast time to first request. Permit.io misses those.

What neither does

Both fail limits / constraints documented, no mandatory sales call, 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.
