Amazon Bedrock
Amazon Bedrock Mantle OpenAI-compatible Chat Completions with Bedrock API keys (Bearer) — no SigV4 SDK.
Le contenu des pages de documentation est en anglais. La navigation, la recherche et l’interface suivent la langue choisie.
Amazon Bedrock’s Mantle endpoint speaks OpenAI-compatible Chat Completions. Deuz targets that wire with a Bedrock API key / short-term bearer token — no AWS SDK, no SigV4, edge-safe.
Default root: https://bedrock-mantle.{region}.api.aws/openai/v1 (adapter appends /chat/completions).
This is not the Bedrock Runtime Converse API. For Converse, put a gateway in front or wait for a dedicated surface.
createBedrock
import { createBedrock } from '@deuz-sdk/core/bedrock';
import { streamChat } from '@deuz-sdk/core';
const bedrock = createBedrock({
apiKey: process.env.AWS_BEARER_TOKEN_BEDROCK!,
region: 'us-west-2',
});
const result = streamChat({
model: bedrock('openai.gpt-oss-120b'),
messages: [{ role: 'user', content: 'Hello from Bedrock Mantle.' }],
});
for await (const delta of result.textStream) {
process.stdout.write(delta);
}Also re-exported from @deuz-sdk/core/providers.
Settings
| Option | Type | Default | Notes |
|---|---|---|---|
apiKey | string | — | Bedrock API key or short-term bearer. Core never reads env. |
region | string | us-east-1 | Mantle regional host. |
baseURL | string | Mantle …/openai/v1 | Override if your region documents /v1 without /openai. |
fetch | typeof fetch | global | Factory wins over deps.fetch. |
headers | Record<string, string> | — | Extra headers. |
Auth is Authorization: Bearer <apiKey> — same as other OpenAI-compat hosts. Key precedence: G1 (apiKeys.bedrock on createClient works).
Model ids
Use the Bedrock / Mantle model id your account exposes (e.g. openai.gpt-oss-120b, xai.grok-4.3). Unknown slugs fall back to conservative registry defaults.
