## Which one, for what

### Argyle (B)

Good for: A lender, tenant screener, benefits agency or background checker whose applicant can sign in to a payroll or gig account, and who needs paystubs, employment records or an income report.

Ahead on:
- Transparency & trust, 83 against 74

Watch for: No price is published. The site has no pricing page, and fees are set in a Service Order agreed with sales

### Finch (BB)

Good for: An application that needs to read employees, pay runs and pay statements from whatever payroll or HR system an employer already uses, or to write benefit deductions back.

Ahead on:
- Agent ergonomics, 71 against 58
- Security & auth, 66 against 48
- Payments & pricing, 30 against 15
- Maintenance & community, 84 against 75

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine

Watch for: Finch cannot create, preview or approve a payroll. Writes are limited to deductions and contributions, on Pro and Premier plans

## Verdicts

**Argyle.** Graded on the REST API. One OpenAPI file covers 91 operations, llms.txt indexes Markdown docs, and a Sandbox with sample users comes with a Console sign-up. Every payroll connection needs the worker to sign in through Link. No prices are published, no idempotency keys were found, and API keys carry no per-key scopes.

**Finch.** Graded on the REST API. An employer grants each connection named product permissions, and limits, error codes and a 99.9 per cent uptime SLA are published. Finch reads payroll and writes deductions but cannot run a payroll. Access tokens never expire, no idempotency keys were found, and writes and most providers need a sales-led plan.

## Before you call either

### Argyle

1. Send HTTP Basic auth with `api_key_id` as the username and `api_key_secret` as the password. Sandbox keys fail with 401 on Production and the reverse
2. Create the user with `POST /v2/users` and an `external_id`, then look it up by `external_id` before retrying. No idempotency key was found
3. Do not read data straight after an account connects. Wait for the account and data webhooks, or for the verification status, before fetching records
4. Follow the full URL in `next` when paging. Do not build cursor values or fetch pages in parallel. `limit` defaults to 10 and stops at 200
5. Stay under 50 requests a second. On 429, queue the request and retry later, not at once
6. Treat `DELETE /v2/users/{id}` as permanent. It removes every resource tied to that user, with no confirmation step

### Finch

1. Send `Finch-API-Version: 2020-09-17` and `Authorization: Bearer <access_token>` on every request. A request without the version header fails with 400
2. Call GET /introspect first to see the connection's products, status and whether it is automated or assisted before choosing endpoints
3. Treat a 202 response as data not ready, not as data. Retry with backoff, and expect up to 14 days for an assisted connection's first sync
4. Stay under 20 requests a minute on organisation endpoints and 12 on pay endpoints across all tokens. Batch IDs, and on 429 wait 60 seconds
5. After a deduction write, poll the job by `job_id` until it completes before enrolling individuals. Enrolment overwrites an existing enrolment
6. Start the MCP server with `--code-allow-http-gets` or a token without the benefits product when only reads are intended
