How this service works

Locus public pay-per-use API

Output

Returns a standard OpenAI-compatible chat completion object containing the model's generated message content, optional tool call selections, token usage statistics, and finish reason. If reasoning_format is set to 'parsed' or 'raw', includes a reasoning field with chain-of-thought output. Response format can be plain text, json_object, or a validated json_schema output.

Example use cases

Automated report drafting agent

“Use the pay-per-use Groq endpoint to generate a one-paragraph executive summary of our Q3 sales data using Llama 4 Scout — cap the output at 300 tokens and return it as plain text.”

Structured JSON extraction pipeline

“Send this customer feedback text to GPT-OSS 120B via the Locus metered API and have it return a JSON object with keys 'sentiment', 'topics', and 'action_items' — use response_format json_schema and limit to 400 tokens.”

Tool-calling agent with open-source LLM

“I need to run a tool-calling session with Qwen 3.6 27B — pass my get_weather and search_web function definitions and let the model decide which to call based on the user message 'What's the weather in Tokyo right now?', with tool_choice set to auto and max 256 tokens.”

When to prefer

Choose this endpoint when you need pay-as-you-go LLM inference with no subscription, billed automatically in USDC via x402 micropayments. Ideal for agents that need to call open-source models (Llama, Qwen, GPT-OSS) sporadically without committing to a monthly plan. Prefer this over direct Groq API when you need automatic per-call billing settled on-chain, or when building agentic pipelines that must track and authorize exact spend ceilings per request.

Side effects

Payment authorization failure if x402 header is missing or USDC balance is insufficient
Model ID not recognized — must use one of the supported models (Llama 3.1/3.3, GPT-OSS 20B/120B, Llama 4 Scout, Qwen 3.6 27B)
max_completion_tokens not provided — required for x402 signed authorization ceiling
Token limit exceeded if max_completion_tokens is set too low for the requested task
Rate limiting or capacity errors from Groq backend during high load
Malformed messages array causes 400 validation error
Tool definitions exceeding 128 items are rejected
