How this service works

[OI]-compatible LLM inference API for autonomous agents. Supports reasoning, coding and chat workloads across 10 frontier models (GPT-5.5, GPT-5.6, GLM 5.3, Kimi K3, DeepSeek V4, MiniMax M3). Pay per request with USDC on Base using x402. No prepaid balance required, no API key, no account.

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.”

When 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

Input

Schema · Request body

Field	Type	Description
model	string	Model id from GET /v1/models, e.g. glm-5.3. No provider prefix.
stream	boolean	SSE streaming.
messages	array	Chat messages, [OI]-compatible {role, content}.
max_tokens	integer	Output token budget. Sets your spending cap; actual usage is what gets settled (true-up).
temperature	number	Sampling temperature.
max_completion_tokens	integer	Alias of max_tokens (gpt-5.x models).

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.
