How this service works
Exact EVM address, calldata, Uniswap V2/V3 and impermanent-loss math. Pay per call in USDC on Base via x402.
Output
Returns a JSON object with a 'choices' array containing the assistant's reply message (role and content), plus a 'usage' object with token counts. No streaming — the full response is returned in one payload.
Example use cases
Agent sub-task cheap text generation
“I need you to use a cheap LLM to summarize this paragraph in one sentence: 'Cloudflare Workers allow serverless code execution at the edge, reducing latency for global users by running computations close to the end user rather than in a centralized data center.'”
Classify customer feedback at low cost
“Classify the sentiment of this customer review as positive, negative, or neutral using the cheap Llama 3.1 inference endpoint: 'The product arrived on time but the packaging was damaged and the manual was missing.'”
Draft a short email reply
“Use the Llama 3.1 8B model to draft a polite two-sentence reply to this email: 'Hi, I wanted to follow up on my refund request from last week — any updates?'”

Endpoint
POSThttps://golf-evm-math.x402-evm-math.workers.dev/v1/chat/completions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cheap, keyless LLM inference at $0.001/call and can accept Llama 3.1 8B quality output. Ideal for agent pipelines where sub-tasks need text generation at scale without managing API keys or subscriptions. Prefer over OpenAI or Anthropic APIs when cost minimization and pay-per-call micropayment (x402/USDC) billing are priorities, and when streaming is not required.
Side effects
- Payment failure via x402 if USDC balance is insufficient or the x402 header is malformed
- Malformed request body (missing required 'messages' field) returns a 4xx error
- Model context length exceeded for very long conversation histories
- Cloudflare Worker timeout for unusually complex prompts
- No streaming support — clients expecting SSE will not receive incremental tokens
