DDG Embeddings API
x402
DDG Embeddings API is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.0005/call, status unknown (last checked 2026-09-15).
Generates vector embeddings for input text via a machine-payable (x402 USDC) endpoint operated by Daedalus Development Group.

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 and the computed embedding vector(s) for the submitted text input, ready for downstream use in similarity search, clustering, classification, or retrieval-augmented generation pipelines.
Example use cases
Semantic search index construction
“Take these 50 product descriptions and generate embeddings for each one so I can build a semantic search index — use the DDG embeddings endpoint and pay per call with USDC.”
RAG pipeline query encoding
“I need to embed this user query — 'best practices for container security' — as a vector so I can run a similarity search against my document store. Use DDG's embeddings service for it.”
Duplicate content detection
“Generate embeddings for these two support ticket texts so I can check their cosine similarity and flag them as duplicates if they're too close: 'My account won't load' and 'I can't access my account page'.”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/embeddingsWhen to prefer
Choose this endpoint when you need pay-per-call text embeddings without a subscription or API key, and your agent is already operating on x402-compatible crypto payment rails (USDC multi-chain). Ideal for sporadic embedding needs in agentic workflows where spinning up an OpenAI or Cohere account is overhead, or when you need a crypto-native, machine-payable embedding service with no human billing setup.
Side effects
- Payment not received or insufficient USDC balance — HTTP 402 returned before processing
- Malformed JSON body or missing required fields (input, output) — likely 400 error
- Provider backend unavailable — service may return 500 or timeout
- Unsupported bodyType or method enum value — schema validation failure
- Network timeout if the embedding model backend is under load
