LLM inference API, large model: Llama 3.3 70B or gpt-oss-120b

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

LLM inference with a large open model: send a prompt (optional system prompt, up to 1,024 output tokens) and get an answer from Llama 3.3 70B Instruct or OpenAI gpt-oss-120b in one call, with no provider account; OpenAI-compatible at /v1/chat/completions by model name. Use when a small model is not enough: reasoning, drafting, analysis and Q&A inside an agent workflow.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/llm/inference?prompt=Explain%20x402%20in%20one%20sentence."

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "model": "@cf/meta/llama-3.3-70b-instruct-fp8-fast",
  "response": "x402 lets software pay for an HTTP request with a stablecoin by answering a 402 Payment Required challenge."
}
