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**Square.** The REST API has a public OpenAPI 3.0 spec, OAuth scopes split by read and write for each resource, idempotency keys on writes and a free sandbox. The MCP server is in beta and its remote instance reaches production only. No numeric REST rate limits or SLA were found, and the status page recorded widespread errors on 27 September 2026.\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### Square\n\n1. Test against the sandbox first with the local MCP server and `SANDBOX=true`. The remote server at mcp.squareup.com reaches production only\n2. Set `DISALLOW_WRITES=true` on the local MCP server when the task only reads\n3. Call `get_service_info`, then `get_type_info`, before each `make_api_request`. The request body is otherwise untyped\n4. Send a fresh `idempotency_key` on every write, and reuse it when retrying the same write\n5. Pin `Square-Version` in each request. Use a page cursor within 5 minutes of receiving it\n\n## Questions\n\n### Which is better for AI agents, Fabric or Square?\n\nSquare scores 69.2 (B) on agent readiness against Fabric's 43.7 (E), and leads in every scored category.\n\n### Do Fabric and Square need an API key?\n\nFabric uses an OAuth sign-in. Square takes an API key or an OAuth sign-in.\n\n### Can an agent call Fabric and Square without installing anything?\n\nYes. Fabric has a hosted endpoint at https://api.fabric.inc/v3 and Square at https://mcp.squareup.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/fabric-vs-square.json, and with the fewest tokens: https://www.anchorterminal.com/compare/fabric-vs-square.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"fabric\", \"b\": \"square\"}`.
