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
Returns a JSON object with ok:true, a choices array containing assistant messages (role + content), and a receipt object confirming the x402 protocol payment settlement.
Example use cases
On-demand AI answers for autonomous agents
“I need my agent to ask 'what are the top three risks of deploying smart contracts without audits?' and pay for each answer automatically with USDC — use the DDG x402 chat endpoint and give me back whatever the assistant says.”
Pay-per-call LLM without subscriptions
“Query the DDG chat completion service with the message 'summarize the key differences between proof-of-work and proof-of-stake' and settle the $0.01 USDC charge via x402 — no subscription needed, just pay as you go.”
Agent pipeline step with crypto-settled AI
“In my automated research pipeline, send 'list five emerging battery technologies for electric vehicles' to the DDG agent-payable chat API, auto-pay with multi-chain USDC, and return the assistant's response for downstream processing.”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/chat/completions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs pay-per-call LLM completions billed in USDC via the x402 protocol without requiring a subscription or API key account — ideal for autonomous agents that need to self-fund queries on-chain and receive bounded, auditable results with payment receipts.
Side effects
- Payment not settled — x402 handshake fails, returns 402 with payment instructions
- Malformed request body — missing required input/output fields returns validation error
- Insufficient USDC balance — payment rejected before completion is served
- Provider backend unavailable — upstream LLM service unreachable, returns 5xx
- Unsupported HTTP method — only POST/PUT/PATCH accepted, others return 405
