How this service works

Pay-per-call Amazon Bedrock proxy on x402 and MPP.

Output

Returns a JSON object containing the generated text completion, the model name used, a finish reason (e.g. 'end_turn'), a response ID, and a usage breakdown showing prompt tokens, completion tokens, and total tokens consumed.

Example use cases

Answering user questions with Nova Lite

“Send this user question to amazon.nova-lite-v1:0 via Bedrock with up to 256 tokens and temperature 0.5: 'Can you explain the difference between supervised and unsupervised machine learning?'”

Multi-turn customer support chatbot

“Continue this support conversation using amazon.nova-lite-v1:0 on Bedrock — the system prompt says 'You are a helpful support agent', the user previously asked about billing, and now they're asking 'How do I update my payment method?' Use max 300 tokens.”

Creative writing with controlled randomness

“I need Bedrock's Nova model to write a short story opening based on this prompt: 'A lighthouse keeper discovers a mysterious message in a bottle.' Use temperature 1.2 and allow up to 800 tokens.”

Technical details

Endpoint

POSThttps://aws-bedrock-agent-api.vercel.app/api/chat?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need pay-per-call access to Amazon Bedrock models (especially Amazon Nova) without managing AWS IAM credentials or infrastructure, and when your agent workflow supports x402 or MPP micropayment protocols. It is especially suitable for agents making sporadic or low-volume inference calls where a monthly subscription is wasteful. Prefer alternatives if you need streaming responses, function calling, or models not available on Bedrock.

Side effects
