How this service works
Paid AI API endpoints via x402 micropayments
Output
Returns a JSON object containing a response ID and a choices array, where each choice includes a message object with a role ('assistant') and the generated text content from Claude.
Example use cases
On-demand AI writing assistant
“Have Claude write me a concise product description for a noise-cancelling headphone, keep it under 150 tokens with a temperature of 0.5 — I want to pay per call, no subscription.”
Autonomous agent sub-task reasoning
“Send this reasoning task to Claude as part of my agent pipeline: 'Given the following customer complaint, suggest the top 3 resolution steps' — use 300 max tokens and temperature 0.3.”
Quick factual Q&A with Claude
“Ask Claude to answer 'What are the main differences between RISC and CISC processor architectures?' in a clear, concise way — max 200 tokens, and I want to stream the response.”

Choose this endpoint when you need access to Anthropic's Claude model on a strict pay-per-call basis using USDC micropayments via the x402 protocol, without committing to a subscription or managing Anthropic API keys directly. Ideal for agents or applications with intermittent, low-volume, or cost-sensitive Claude usage patterns.
Side effects
- Payment failure or insufficient USDC balance returns a 402 Payment Required error
- Invalid or malformed messages array returns a 400 validation error
- Exceeding model token limits may truncate output or return an error
- Network timeout if the model takes too long, especially for large max_tokens values
- Missing required 'messages' field returns a schema validation error
