Access needs a sales contract, with no public price or self-serve trial. The commerce docs are labelled legacy, the newest release notes date from July 2025, and no status page was found.\n\n**Swell.** Live /:models schema with field types and descriptions for every store. One full-access secret key per environment, with no scoped or read-only key.\n\n## Before you call either\n\n### Fabric\n\n1. Get the tenant ID and a System App client ID and secret from the merchant's Copilot admin, with the narrowest role the task needs\n2. Request a new system token from {authURL}/v1/token every 10 minutes, since system apps receive no refresh token\n3. Send x-fabric-tenant-id on every call, and x-fabric-channel-id where the merchant sells in more than one channel\n4. Page order searches with offset and limit, because the default response returns 10 orders\n5. Read errorCode and context.endpoint in Orders and Inventory errors, and check for duplicates before retrying a write\n\n### Swell\n\n1. Call GET /:models once and cache it. It's the ground truth for custom fields\n2. Check `result.errors` after every write. A failed validation still returns 200\n3. Use `$set` to replace an array. A plain PUT merges arrays by element id and never shrinks them\n4. Use an sk_test_ key while testing. A bare sk_ prefix is live\n5. Keep `expand` and `include` small. Each level past the first three points adds rate-limit weight\n\n## Questions\n\n### Which is better for AI agents, Fabric or Swell?\n\nSwell scores 55 (C) on agent readiness against Fabric's 43.7 (E), and leads in 4 of 7 scored categories. Fabric leads on schema \u0026 documentation, security \u0026 auth and transparency \u0026 trust.\n\n### Do Fabric and Swell need an API key?\n\nFabric uses an OAuth sign-in. Swell needs an API key.\n\n### Can an agent call Fabric and Swell without installing anything?\n\nYes. Fabric has a hosted endpoint at https://api.fabric.inc/v3 and Swell at https://api.swell.store.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/fabric-vs-swell.json, and with the fewest tokens: https://www.anchorterminal.com/compare/fabric-vs-swell.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"fabric\", \"b\": \"swell\"}`.
