How this service works

Locus public pay-per-use API

Output

Returns a chat completion response in OpenAI-compatible format containing the assistant's generated message, model used, token usage counts, and finish reason. The response mirrors the OpenRouter/OpenAI chat completions schema with the `choices` array holding the assistant reply.

Example use cases

Microbilling agent for dynamic LLM tasks

“Use the Locus x402 pay-per-use gateway to ask google/gemini-2.5-flash to extract all action items from this meeting transcript, limit the response to 500 tokens — I want to be billed in USDC only for what I actually use.”

Multi-model comparison with crypto billing

“Send the same user prompt — 'Write a haiku about distributed systems' — to both anthropic/claude-haiku-4.5 and openai/gpt-oss-120b through the Locus OpenRouter x402 endpoint with max_tokens 100, so I can compare outputs and pay per call.”

Serverless AI chatbot backend

“My chatbot needs to respond to a user message 'How do I reset my password?' using anthropic/claude-sonnet-5 with a system prompt 'You are a friendly customer support agent', max 200 tokens, temperature 0.5 — route it through the x402 Locus OpenRouter API so each reply is billed at $0.001 USDC.”

When to prefer

Choose this endpoint when you need pay-per-use LLM inference billed in USDC micropayments via the x402 protocol — ideal for agents that want to avoid monthly API subscriptions, need to access multiple model providers (Anthropic, OpenAI, Google) through a single endpoint, or are building autonomous systems where cost is metered per individual inference call. Prefer this over direct OpenAI or Anthropic APIs when you want crypto-native billing without pre-purchase commitments.

Side effects

Payment authorization failure if x402 USDC balance is insufficient — returns 402 Payment Required
Invalid or unsupported model ID returns a 400 or model-not-found error
max_tokens not provided — required for x402 cost ceiling enforcement, will likely reject the request
Token limit exceeded if prompt plus max_tokens surpasses the model's context window
Rate limiting or upstream OpenRouter errors propagated as 5xx responses
Malformed messages array (wrong role values or missing content) causes validation errors

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.
