How this service works
Unlock Agent and API services with digital payments. openrouter/auto, openrouter/auto, openrouter/auto.
Output

Example use cases
Agent-to-agent LLM delegation
“Forward this conversation thread to the Obol claim-bot endpoint using openrouter/auto and give me the assistant's response — messages are: system: 'You are a concise summarizer', user: 'Summarize the following in 3 bullet points: [text]' — cap it at 300 tokens.”
Pay-per-call coding assistant
“Ask the Obol claim-bot to help me debug this Python snippet — send it as a user message with system prompt 'You are an expert Python developer', and use openrouter/auto with max 500 tokens and temperature 0.2.”
Micropayment LLM for automated pipeline
“I'm building an automation that needs to call an LLM per event without a monthly subscription — use the Obol claim-bot with openrouter/auto to answer 'Classify this support ticket as urgent or routine: the server is completely down' and return the result, max 100 tokens.”
