The API has idempotency keys on writes, a required preview before approval and queryable request logs. No price is public, a sandbox key comes through Check's sales team, and one API key carries the whole partner account.\n\n**PayFit.** A public OpenAPI 3.0 file, llms.txt and scoped keys let a paying customer's agent read payroll outputs and write absences. The API cannot run or approve a payroll, new partner integrations are not being accepted, and no idempotency keys or SDKs were found.\n\n## Before you call either\n\n### Check\n\n1. Use https://sandbox.checkhq.com with the sandbox key and https://api.checkhq.com with the production key. A key is not valid across environments\n2. Preview a payroll before approving it, then pass `preview_started_at` to POST /payrolls/{id}/approve so a stale preview fails with 409\n3. Send `X-Idempotency-Key` on every write. Keys expire after 24 hours, so list the resource before retrying later than that\n4. On 429 wait for `Retry-After`. The limit is 10 requests a second in sandbox and for partners paying fewer than 1,000 payees a month, with 100 concurrent requests\n5. Connect the MCP server with `?read_only=true` or `X-MCP-Readonly: true` unless writes are intended. In production, approving a payroll moves money\n\n### PayFit\n\n1. Have a company admin create the key at app.payfit.com/integrations/hub/api with only the scopes the task needs. The key is shown once\n2. POST the key to `https://oauth.payfit.com/introspect` to get `company_id`, then call `https://partner-api.payfit.com/companies/{companyId}/...`\n3. Page lists with `nextPageToken` and `maxResults`, which defaults to 10 and stops at 50\n4. Check before repeating a failed POST. There is no idempotency key, and `POST /absences` creates an absence that is already validated\n5. A collaborator or contract created through the API stays incomplete until an HR admin finishes it in the PayFit app, and a new contract takes 2 to 5 minutes to appear\n\n## Questions\n\n### Which is better for AI agents, Check or PayFit?\n\nCheck scores 67.5 (B) on agent readiness against PayFit's 55.5 (C), and leads in 4 of 7 scored categories. PayFit leads on payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Check and PayFit need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Check and PayFit without installing anything?\n\nCheck has a hosted endpoint at https://api.checkhq.com.
