151+Mantle also exposes an Anthropic Messages route that carries Claude models through the same bearer-authenticated streaming path. Claude Opus 4.7 (`amazon-bedrock-mantle/claude-opus-4.7`) is callable through this route with provider-owned streaming, so AWS bearer tokens are not treated like Anthropic API keys.
152+153+When you pin an Anthropic Messages model on the Mantle provider, OpenClaw uses the `anthropic-messages` API surface instead of `openai-completions` for that model. Auth still comes from `AWS_BEARER_TOKEN_BEDROCK` (or the minted IAM bearer token).
