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**Kintsugi.** The docs are built for machine readers, with llms.txt, Markdown pages, a public OpenAPI 3.1 file, a dated changelog and an MCP server whose 55 tools carry read-only and destructive annotations. API keys need the custom-priced Premium plan and carry no scopes, no general rate limit is published, and breaking changes reached the pinned 2026-07-21 release in 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### Kintsugi\n\n1. Send `Api-Key` and pin `Api-Version` (for example `2026-10-06`) on Tenanted API calls to `https://api.trykintsugi.com`. Without the header a request runs against `2026-07-21`\n2. Use `x-api-key` and `x-organization-id` with `/v1` paths for the SDKs and the docs MCP server. They don't cover the Tenanted API\n3. Call `POST /tax-estimations` for a quote. Nothing is stored. Record the sale with a transaction create, which answers 202, then check `processingStatus` before reading tax totals\n4. Always send `externalId` on creates. A repeat with the same `externalId` and `source` returns the stored record with 200 and doesn't apply the new fields\n5. Branch on the error `code`, not the message. Retry 429, 500 and 503 with exponential backoff, and restart paging from the first page on `stale_cursor`\n\n## Questions\n\n### Which is better for AI agents, Anrok or Kintsugi?\n\nAnrok and Kintsugi score within a point of each other on agent readiness, 61.6 (C) and 60.7 (C). Kintsugi leads on schema \u0026 documentation, agent ergonomics, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Anrok and Kintsugi need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Anrok and Kintsugi without installing anything?\n\nYes.
