Multi-turn code review chatbot

When to prefer

Choose this endpoint when you need fast, low-cost Claude Haiku 4.5 inference in an agentic MCP-compatible pipeline and want pay-per-call USDC billing on Base instead of a subscription. Ideal for agents that need occasional Claude completions without provisioning an Anthropic API key. Not suitable when you need more than 256 output tokens or require a different Claude model tier.

Side effects

Payment failure: insufficient USDC balance or x402 payment not accepted — returns 402 Payment Required
Output truncation: responses are hard-capped at 256 tokens, long answers will be cut off
Model overload: upstream Anthropic API rate limits may cause 429 or 503 errors
Invalid prompt format: malformed MCP tool call may return 400 Bad Request
Network timeout: streamable HTTP connection dropped mid-response
