Output
Returns an OpenAI-compatible JSON object with a choices array containing the assistant's message (role + content), a finish_reason, and a usage block with prompt_tokens and completion_tokens counts.
Example use cases
Agent sub-task reasoning without API key
“I need you to call GLM-5.3-flash via FarOut to answer this question for my pipeline: 'What are three edge cases I should handle in a Solidity transfer function?' — keep the response under 300 tokens, no streaming.”
On-demand coding help for autonomous workflow
“Ask GLM-5.3-flash to write a Python function that parses a JSON array of timestamps into ISO 8601 format, max 400 tokens, temperature 0.2 — pay per call using USDC, no account needed.”
Chat response generation for agent with crypto payment
“Use FarOut's pay-per-call gateway to run a GLM-5.3-flash chat: the user just said 'Summarize the pros and cons of proof-of-stake consensus' — give me the assistant reply, up to 250 tokens.”
Technical details
Endpoint
POSThttps://farouter.tech/v1/models/glm-5.3-flash/chat/completionsWhen to prefer
Choose this endpoint when you need OpenAI-compatible LLM inference without API keys, accounts, or prepaid credits — paying per call in USDC on Base. It is ideal for autonomous agents that need to self-fund inference on demand. Prefer it over hosted API providers when you want frictionless crypto-native payment for one-off or low-volume calls to GLM-5.3-flash specifically.
Side effects
- Payment rejected or insufficient USDC balance on Base — 402 Payment Required
- Invalid or unsupported model ID — 400 Bad Request
- messages array empty or malformed — 400 validation error
- max_tokens exceeds model context limit — 400 or truncated response
- Upstream model provider outage — 503 or timeout
- Stream requested but client doesn't handle SSE — partial or broken response
