- per-client-IP token bucket on POST /api/traverse (EXPLOREDNS_RATE_LIMIT,
default 30/1h; direct localhost exempt, proxied clients are not)
- optional usage webhooks (EXPLOREDNS_WEBHOOK_URL): start/complete JSON
events, fire-and-forget with 5s timeout + one retry so a dead receiver
never delays a job
- post-traversal version.bind fingerprinting exposed at
GET /api/traverse/{id}/servers (pending until ready) and announced via
an SSE "servers" event; never delays job completion
- /api/health reports the serving Fly region (FLY_REGION) for observing
anycast routing from a roaming client
