## Which one, for what

### ComplyCube (B)

Good for: An agent that creates clients, uploads documents, starts document, identity and AML screening checks and reads results for a regulated business, with low entry cost ($99 a month) and a scripted sandbox.

Ahead on:
- Reliability, 84 against 68
- Payments & pricing, 27 against 15

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: One API key per environment with no scopes. The docs say keys carry many privileges

### Plaid Identity Verification (B)

Good for: US, Canadian and UK companies that want KYC with data source checks, documents and selfies, especially those already on Plaid or wanting Monitor screening in the same flow.

Ahead on:
- Schema & documentation, 91 against 78
- Agent ergonomics, 75 against 60
- Security & auth, 61 against 52
- Maintenance & community, 83 against 74
- Transparency & trust, 77 against 63

Watch for: No public prices. Rates appear only after a Production application

## Verdicts

**ComplyCube.** A sandbox with its own key and scripted outcomes, a public OpenAPI spec, Markdown docs and an audit log API suit an agent running verification checks. Each environment has one unscoped key, no idempotency keys were found, and the only published terms are undated and read as website terms.

**Plaid Identity Verification.** Plaid Identity Verification has four typed endpoints in Plaid's public OpenAPI file, an idempotent create, a backend-only flow for data source checks and frequent changelog entries. Prices appear only after applying for Production, the secret has no scopes, and the rate-limit and error pages are disallowed to crawlers.

## Before you call either

### ComplyCube

1. Send the key bare in the `Authorization` header, with no Bearer prefix. Keys start `test_` or `live_`
2. Create a client first, then documents or live photos for it, then `POST /v1/checks` with the client and upload IDs
3. Stay under 10 requests a second live and 5 in the sandbox. On 429, back off exponentially with jitter, starting at 30 seconds
4. A badly formed filter returns 200 with no results, so check filter names before trusting an empty list
5. Checks are asynchronous. Subscribe to webhooks, verify the `ComplyCube-Signature` HMAC-SHA256 header, and expect duplicate and out-of-order events

### Plaid Identity Verification

1. Pass `is_idempotent: true` to /identity_verification/create so a retry returns the existing session
2. Use the backend-only flow (data source template, `gave_consent: true`) when you already hold the user's details. Documents and selfies need the person in Link
3. Wait for the STATUS_UPDATED webhook or poll /identity_verification/get. Link's onSuccess doesn't mean the user passed
4. Don't issue retries casually. Each retry is a new session billed again
5. Enable Sandbox for Identity Verification on the Dashboard Products page before the first call
