The AP and AR API signs in with a user's password and has no scopes, no idempotency key protects payment calls, and no official SDK was found.\n\n**Expensify.** One endpoint exports reports through caller-written templates and creates expenses, reports, rules and workspace settings, with limits of 5 requests per 10 seconds published and a status page that tracks the API separately. There is no OpenAPI spec, changelog, SDK, pagination or idempotency key, and one credential pair carries the whole account's rights.\n\n## Before you call either\n\n### BILL\n\n1. Sign in with `POST /v3/login` and send `sessionId` and `devKey` as headers on every AP and AR call. The session expires after 35 minutes idle\n2. Send the `apiToken` header alone on `/v3/spend/` paths. Spend \u0026 Expense calls need no login and are limited to 60 a minute per token\n3. Complete the MFA challenge before `POST /v3/payments`. An untrusted session fails with `BDC_1361`\n4. Read back payments before retrying a failed `POST /v3/payments`. No idempotency key is accepted, so a blind retry can pay twice\n5. Keep to three concurrent requests per developer key per organisation and 20,000 an hour. After `BDC_1144`, wait for the next hour\n\n### Expensify\n\n1. POST `requestJobDescription` as a form field to the single endpoint. Keep it out of the URL query string, because it carries the secret\n2. Read `responseCode` in the body on every reply. HTTP status can be 200 on failure, and validation errors use 410\n3. Stay under 5 requests per 10 seconds and 20 per 60 seconds. No Retry-After header is documented, so space retries yourself\n4. Export in two calls. A `file` job returns a filename, then a `download` job fetches it. Amounts are in cents\n5. Don't retry a create job blindly. No idempotency key exists, so export and check before resending. Set `dry-run` to true when testing the Advanced Employee Updater\n\n## Questions\n\n### Which is better for AI agents, BILL or Expensify?\n\nBILL scores 60.9 (C) on agent readiness against Expensify's 41.1 (E), and leads in 6 of 7 scored categories. Expensify leads on payments \u0026 pricing.\n\n### Do BILL and Expensify need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call BILL and Expensify without installing anything?\n\nYes.
