  MetaLend does not publish a separate hosted sandbox with fake balances, but it
  DOES publish a default API key for agent testing/integration and exposes a dev
  API host. All values below are published verbatim by the provider — none are
  invented. Value-moving operations still execute against real chains, so agents
  must obtain explicit signing consent.
hosts:
  production: https://api.metalend.tech
  dev: https://api.dev.metalend.tech
test_credentials:
  default_api_key:
    header: X-API-Key

    note: Provider-published default key for agent testing/integration. Project owners create their own key at https://developer.metalend.tech.

    note: Localhost is always allowed but must be specified explicitly.

gotchas:
  - Cloudflare blocks direct Python/curl requests; route through agentcash fetch or a browser-trusted client.
  - Agentic wallets strip the Authorization header; use X-MetaLend-JWT instead.
