How this service works

Voice-agent reply turn — low-latency chat after WebSocket ASR flux and smart-turn detection. POST messages[]; synthesize with POST /v1/tts/aura-2-en. Bundle: GET /v1/models?bundle=voice.

Output

A JSON object containing the model identifier (e.g. '@cf/meta/llama-3.2-1b-instruct') and a 'response' string with the assistant's generated reply text.

Example use cases

Example prompt

“Can you ask the GEDX402 fast chat endpoint to explain what a merkle tree is? Use a single user message saying 'What is a merkle tree and why is it useful?' and limit the reply to 200 tokens.”

Technical details

Endpoint

GEThttps://chat.gedx402.com/v1/chat/fast?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a fast, cheap LLM chat completion (~$0.005/call) without registering for an API key, and you can pay in USDC on Base, Polygon, Arbitrum, World, or Solana via the x402 protocol. Best for low-latency, single-turn or short multi-turn conversations where cost per call matters and crypto-native payment is acceptable. Prefer over OpenAI or Anthropic APIs when you want keyless, permissionless AI inference paid on-chain.

Side effects

Payment not received or insufficient USDC — 402 Payment Required returned
max_tokens exceeds 4096 — validation error
Malformed messages array (missing role or content) — 400 Bad Request
Network timeout on Workers AI backend — 503 or timeout error
Unsupported payment network specified — payment rejection

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
