Aidbox vs Validic Inform

Aidbox

Graded on the FHIR REST API of an Aidbox instance the owner runs. Monthly releases, two-year LTS lines, SMART on FHIR, AccessPolicy rules and AuditEvent logging are documented, and a free development licence needs no sales call. Aidbox has no rate limiting of its own, its MCP module is alpha, and no terms of service were found on the website.

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.

Aidbox

1. Ask the operator for a Client with an AccessPolicy limited to the task. Don't rely on the public MCP policy, which the docs mark unsafe
2. Use If-None-Exist on creates and conditional update on identifiers so retries don't duplicate records
3. Use _elements and _count to keep responses small, and follow the Bundle's paging links
4. Throttle yourself. Aidbox applies no rate limit, so a burst lands on the customer's database
5. Don't load real patient data into an instance on a development licence

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
