Mir – Portable participation history across platforms (open sandbox)

MIR (Memory Infrastructure Registry) lets platforms query a user's behavioral history across other platforms — without those platforms ever talking to each other.

Every platform starts from zero. A seller with 500 five-star reviews on one marketplace is a complete unknown on another. MIR is the infrastructure layer that fixes this. Partners submit events via API, and when any partner resolves a user, they get aggregated signals from all participating platforms — with partner identities anonymized.

The sandbox gives you an instant API key (magic link login). Two curl commands to try it:

curl -X POST https://myinternetreputation.org/events \ -H "Content-Type: application/json" \ -H "x-api-key: YOUR_KEY" \ -d '{"userExternalId": "user-123", "eventType": "transaction.completed"}'

curl https://myinternetreputation.org/sandbox/resolve?userExternalId=user-123 \ -H "x-api-key: YOUR_KEY" Use user-123 — when multiple people submit events for the same user, resolve returns history from all of them.

Stack: Express, TypeScript, PostgreSQL, Redis. Sandbox is isolated from production, rate-capped at 5k events/day.

Happy to answer questions about the architecture or trust model.
