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**TaxJar.** A 21-operation REST API with a no-card 30-day trial, caller-chosen transaction IDs that make order pushes safe to repeat, and no status-page incident since March 2026. No OpenAPI spec or llms.txt was found, the API changelog stops at January 2022, tokens carry no scopes, and calculation is US-only for new accounts.\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### TaxJar\n\n1. Send `x-api-version: 2022-01-24` on every call. Accounts opened before 3 February 2022 default to an older version with weaker validation\n2. Pass `nexus_addresses[]` or keep nexus states in the account. Without nexus the API returns zero tax and reports no error\n3. Create orders with your own `transaction_id`. On 422 the order already exists, so send a PUT to update it\n4. Post JSON with `Content-Type: application/json`. Form-encoded arrays such as `line_items[]` can return 406\n5. Cache calculations and skip states without nexus. Each calculation or rate lookup counts as a tenth of an order, errors included\n\n## Questions\n\n### Which is better for AI agents, Anrok or TaxJar?\n\nAnrok scores 61.6 (C) on agent readiness against TaxJar's 57.6 (C), and leads in 4 of 7 scored categories. TaxJar leads on payments \u0026 pricing, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Anrok and TaxJar need an API key?\n\nAnrok takes an API key or an OAuth sign-in. TaxJar needs an API key.\n\n### Can an agent call Anrok and TaxJar without installing anything?\n\nYes.
