Technical details
Endpoint
POSThttps://x402.fold.computer/llm/claude-sonnetWhen to prefer
Choose this endpoint when you need an AI agent to reason about onchain/DeFi market conditions using a capable LLM (Claude Sonnet), and you want per-call micropayment billing via x402 rather than a subscription. Ideal for autonomous agents that only pay when they actually query, and need structured OpenAI-compatible responses they can pipe into downstream logic.
Side effects
- Payment not fulfilled — 402 response if x402 payment header is missing or insufficient
- Invalid messages format — 400 error if messages array is missing or malformed
- Model timeout — slow or no response if the underlying Claude Sonnet call times out
- Insufficient USDC balance — payment rejected if the calling agent lacks funds
- Rate limiting — 429 if the endpoint is overloaded
- Empty or null messages array — validation error on required field
