The OpenAPI declares no securitySchemes (apiKey / http / oauth2 / openIdConnect / mutualTLS): all read endpoints (tokens, markets, candles, trades, book, user portfolio/orders) are public and unauthenticated, keyed only by the EVM wallet address in the path (e.g. /users/{user_address}/portfolio). Write access is via POST /exchange, which accepts a signed EVM transaction body — authorization is cryptographic (the user signs the order/trade transaction with their wallet key), not an API key or OAuth token. The GTE Python SDK (packages/gte-packages.yml) constructs and signs the transaction body. schemes: []
