How this service works

Fixed-price chat completions for glm-5.3 on FarOut: flat $0.002 per call (includes up to 4,000 input + 1,000 output tokens). Rate: $0.090/1M input tokens, $0.282/1M output tokens. Pay with USDC on Base using x402. No API key, no account, no prepaid balance.

Output

Returns an OpenAI-compatible JSON object with a choices array containing the assistant message, finish_reason (e.g. 'stop'), and a usage object with prompt_tokens and completion_tokens counts.

Example use cases

Crypto-native agent coding helper

“Ask GLM-5.3 via FarOut to review this Python snippet for bugs and suggest fixes, paying per call with USDC — system prompt: 'You are a senior Python engineer', user message: the code below, max 800 tokens, temperature 0.1.”

Autonomous agent reasoning loop

“I need my agent to send a multi-turn conversation to GLM-5.3 on FarOut — include the prior assistant turns in the messages array, cap the reply at 1024 tokens, and stream the response back to me.”

One-off question, no subscription

“Without setting up any account or API key, have FarOut call GLM-5.3 with my single user message 'Summarize the pros and cons of retrieval-augmented generation in three bullet points' and cap the output at 300 tokens.”

When to prefer

Choose this endpoint when you need GLM-5.3 specifically (strong multilingual and reasoning performance) and want true pay-per-call billing via USDC with no account registration, no prepaid credits, and OpenAI-compatible message format — ideal for autonomous agents that need to pay for inference programmatically without human-managed API keys.

Side effects

Payment rejected — insufficient USDC balance or x402 payment not accepted, returns 402 Payment Required
Invalid model id — model field not matching a listed model returns 400
Messages array empty or missing role/content — returns 400 validation error
max_tokens too large for model context window — returns 400 or truncated output
Rate limiting or upstream model unavailability — returns 503 or timeout
Network error reaching farouter.tech — connection refused or DNS failure
