## Which one, for what

### Alloy (D)

Good for: Banks and fintechs that already run onboarding through Alloy and want an agent to submit journey applications, read decisions and work investigations.

Watch for: No public prices, trial or self-serve sign-up. Access starts with a demo request

### 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.

## Verdicts

**Alloy.** Alloy's public docs cover journeys, evaluations, entities, documents, cases and investigations, with llms.txt, Markdown pages, OpenAPI fragments and rate-limit headers with retry-after. Access is sales-led with no public price or trial, credentials have no scopes, there is no idempotency key or server SDK, and inputs vary by each customer's workflow.

**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

### Alloy

1. Get the account's base URL from the customer. Defaults are api.alloy.co and sandbox.alloy.co, and some accounts have their own hosts
2. Use unique, prefixed external IDs in sandbox. Sandbox and Production share one data store
3. Read `alloy-ratelimit-remaining`, and on 429 or 5xx wait for `retry-after` with exponential backoff and jitter
4. Expect `running` after about 25 seconds on journey applications and wait for the webhook instead of resubmitting
5. Send the workflow header with account-level keys, since inputs depend on the workflow configured

### 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
