Export every gate config as a portable JSON document
Use when: caller wants a downloadable snapshot of all their gate/routing configuration — e.g. for backup or to migrate off the platform
Returns { schemaVersion, exportedAt, gates } where each gate is its portable configuration (routing strategy, fallback chain, params, agent-gate fields) without runtime state (spending counters, health) or account identifiers. Served with a Content-Disposition: attachment header so browser navigation downloads a file.
Authorizations
Verlon API key (newly minted keys are prefixed sk-vrln-; legacy verlon_* and layer_* keys from prior prefix migrations continue to validate). Generated from the dashboard under Settings → API Keys, or via verlon key create in the CLI.
Response
Portable config document for every owned gate.
