How this service works
Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.
Output
A JSON object with at minimum an 'ok: true' field indicating the judgment was successfully processed, along with any evaluation scores, verdicts, or assessment details returned by the LLM judge for the submitted input/output pair.
Example use cases
Automated LLM response quality scoring
“I have a batch of AI-generated answers to customer support questions and I need each one judged for accuracy and helpfulness — can you run them through the LLM judge one by one and give me scores?”
A/B comparison of two model outputs
“I ran the same prompt through two different models and got two different answers — can you use the LLM judge to evaluate both and tell me which one is better and why?”
RAG pipeline output validation
“My retrieval-augmented generation pipeline just produced an answer — before I show it to the user, can you judge whether the response actually addresses the original question and flag it if it seems off?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/llm-judgeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call LLM-as-judge evaluation with no subscription or account setup, especially when you want to pay via x402 USDC on-chain. Prefer this over self-hosted LLM judges when you want a bounded, managed evaluation artifact without managing provider credentials. At $0.01/call it is economical for high-volume automated evaluation pipelines.
