How this service works
Standard-tier chat/completions (OpenAI-compatible), served by Animica's network. Cheaper than priority, standard latency — priced at 3x settlement gas.
Output
An OpenAI-compatible chat.completion JSON object containing the assistant's reply message, finish reason, model used, and token usage statistics (prompt tokens, completion tokens, total tokens).
Example use cases
Micro-billed agent reasoning step
“I need you to call Animica's chat completions endpoint with the default model, up to 300 tokens, and ask it: 'What are three concise strategies for reducing customer churn in a SaaS business?' — pay per call from my USDC balance.”
No-key LLM for quick content draft
“Use Animica to generate a short product description for a wireless ergonomic keyboard — pick whichever model is available, keep it under 150 tokens, no streaming.”
Automated Q&A inside a serverless workflow
“In my agent pipeline, call the Animica chat completions API with max 500 tokens and ask: 'Summarize the key differences between REST and GraphQL for a junior developer.' Charge it to my x402 wallet.”
Technical details
Endpoint
POSThttps://animica.dev/x402/v1/standard/chat/completionsWhen to prefer
Choose this endpoint when you need a pay-per-call LLM inference API with no monthly subscription or API key setup, particularly when your agent already handles x402 micropayments in USDC. It is ideal for sporadic or bursty usage patterns where a flat-rate subscription would be wasteful, or for agents operating in crypto-native environments that prefer on-chain verifiable micropayments over traditional billing.
Side effects
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Streaming requested (stream: true) is unsupported on this paid path and will be rejected
- Invalid or unrecognized model ID returns an error — check /v1/models first
- Malformed messages array (missing role or content fields) causes a 400 Bad Request
- Exceeding model context length with too many messages or a very high max_tokens may cause an error
- Service unavailability on animica.dev returns 5xx errors
