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**Avalara AvaTax.** The REST API has a public Swagger file with 491 operations, a Markdown page per endpoint and a 90-day trial with no card. Production rate limits and prices per transaction are not published, the API patch notes stop at April 2023, and the tax calculation service was degraded for about 23 hours on 5 and 6 October 2026.\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### Avalara AvaTax\n\n1. Omit `type` or send SalesOrder for an estimate. A type ending in Invoice is recorded, and `commit` set to true locks it for reporting\n2. Retry a timed-out invoice with CreateOrAdjustTransaction, not CreateTransaction, which errors when a committed transaction has the same code\n3. Use sandbox-rest.avatax.com with sandbox credentials for tests. Production is rest.avatax.com and the two accounts are separate\n4. Add `$include=SummaryOnly` or LinesOnly to shrink transaction responses, and page lists with `$top` (1,000 at most) and `$skip`\n5. Call /api/v2/utilities/ping first. It answers without credentials and shows whether the credentials sent were accepted\n\n## Questions\n\n### Which is better for AI agents, Anrok or Avalara AvaTax?\n\nAvalara AvaTax scores 68.8 (B) on agent readiness against Anrok's 61.6 (C), and leads in 6 of 7 scored categories. Anrok leads on reliability.\n\n### Do Anrok and Avalara AvaTax need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Anrok and Avalara AvaTax without installing anything?\n\nYes.
