## Which one, for what

### Metriport Medical API (D)

Good for: US care providers and digital health companies that need a patient's network records as FHIR with webhooks.

Ahead on:
- Agent ergonomics, 70 against 50
- Security & auth, 41 against 30

Also in its favour:
- Open source

Watch for: Every API key has full access, including destructive operations, with no scopes

### Validic Inform (C)

Good for: A remote patient monitoring or wellness app that needs normalised readings from many wearables and home devices, and an agent that wants to start building without a sales call.

Ahead on:
- Reliability, 73 against 45
- Schema & documentation, 75 against 65
- Payments & pricing, 40 against 5
- Transparency & trust, 71 against 56

Watch for: The organisation token is sent as `?token=` in the URL, the only documented option

## Verdicts

**Metriport Medical API.** One network query pulls a patient's records from HIEs, pharmacies and labs and returns deduplicated FHIR, with per-operation rate limits, RFC 7807 errors and AGPLv3 source. Each API key has full access with no scopes, there are no public prices, and the sandbox opens only after Metriport approves the account.

**Validic Inform.** Graded on the Inform REST and Streaming APIs. An agent can create a free developer account through a sign-up API, with only an emailed code needing a person's inbox, and llms.txt plus agent guides document every step. The organisation token travels in the URL query string, the free tier holds synthetic data only, and production access needs an Enterprise contract.

## Before you call either

### Metriport Medical API

1. Check the `errors` array after Start Network Query. It returns 2XX even when some sources fail
2. Wait for `network-query.*` webhooks or poll Get Network Query Status before reading consolidated data, which is cached from the last query
3. Send the resource's `eTag` in `If-Match` on updates to avoid overwriting newer data
4. Keep patient creates under 15 a minute and network queries under 20 a minute per source
5. In sandbox, create patients whose first name matches a pre-defined persona to get example records

### Validic Inform

1. Show the developer the free-tier terms and wait for acceptance before calling `POST /auth/register`
2. Send `Authorization: <id_token>` to sign-up calls, but pass the organisation token as `?token=` on Inform calls
3. Use the customer `uid` in URLs, never Validic's internal `id`, which returns a silent 404
4. Keep date ranges to 30 days or less and page month by month for backfills
5. Unwrap `data` on list responses and treat an empty array as normal on a new account
