How this service works

14 chat models (GPT + Claude), 7 image models, and Jev structured decisions. Pay per request in USDC on Base with x402.

Output

Returns a JSON object in Anthropic's messages format containing the assistant's text response(s), the stop reason (e.g. end_turn), input and output token counts, the model used, and a unique message ID.

Example use cases

Autonomous agent reasoning step

“I need Claude Haiku to act as a helpful assistant and answer this user question: 'What are the pros and cons of index funds vs individual stocks?' — keep it concise, max 500 tokens.”

Structured content drafting

“Use Claude Sonnet with this system prompt — 'You are a professional copywriter' — to write a 200-token product description for my new ergonomic standing desk.”

Code explanation for developer tool

“Have Claude Opus explain what this Python function does and suggest improvements, limiting the reply to 1000 tokens: 'def fib(n): return n if n <= 1 else fib(n-1) + fib(n-2)'”

When to prefer

Choose this endpoint when you need Anthropic-compatible Claude model access (Haiku, Sonnet, Opus) on a pay-per-request basis without committing to an Anthropic subscription or prepaid credits. It is ideal for agents that need occasional or unpredictable Claude inference volumes, want to pay in USDC on Base via x402, or require the standard Anthropic messages format for drop-in compatibility with existing Claude-based code.

Side effects

Missing or invalid model ID returns a 400 error
max_tokens not provided triggers an Anthropic API validation error
Unsupported model string results in a model-not-found error
Insufficient USDC balance or failed x402 payment prevents the request from being processed
Malformed messages array (missing role or content) causes a schema validation failure
Stream mode may require SSE-compatible client handling
