Access needs a seller account arranged through sales, API keys carry no scopes, and no API changelog, SDK or subprocessor list was found.\n\n**Quaderno.** A public OpenAPI 3.1 spec covers 92 operations, with a free sandbox and a status page showing no incident since July 2025. The API key has full account access, there are no idempotency keys, and the newest public API version is dated October 2024.\n\n## Before you call either\n\n### Anrok\n\n1. Send every call as a POST with a JSON body to https://api.anrok.com, including reads such as /v1/seller/products/list\n2. Call createEphemeral for a quote and createOrUpdate only when the invoice is final. createOrUpdate saves the transaction for filing\n3. Reuse the same transaction id on a retry. createOrUpdate overwrites by id, so a repeat doesn't create a second record\n4. Expect transactionFrozenForFiling once a transaction is on a filed return. Negate it with createNegation and write a new id with a suffix such as :s2\n5. On 429 wait the number of seconds in Retry-After. The default limit is 10 requests a second per seller account\n\n### Quaderno\n\n1. Call GET https://quadernoapp.com/api/authorization first. Its `href` gives the account subdomain that every other call needs\n2. Before retrying a failed POST /transactions, list invoices by `processor_id` to check whether the sale was recorded. There is no idempotency key\n3. Treat GET /invoices/{id}/deliver as a write. It emails the invoice to the customer\n4. Correct a final invoice with a credit note. DELETE on invoices returns 410 and PUT accepts only notes, tags, metadata and address fields\n5. Read X-RateLimit-Remaining and X-RateLimit-Reset, and page with `created_before` and `limit` up to 100\n\n## Questions\n\n### Which is better for AI agents, Anrok or Quaderno?\n\nAnrok scores 61.6 (C) on agent readiness against Quaderno's 59.5 (C), and leads in 3 of 7 scored categories.
