# DDG Embeddings API

> 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.

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/embeddings
- Price: $0.0005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ddg-embeddings-api-d696b24d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_E3msiCba5zHGRVCUXp_cu

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ddg-embeddings-api-d696b24d -d '<json body>'
```

Example prompt: Can you generate a vector embedding for the text 'The quick brown fox jumps over the lazy dog' using the DDG embeddings service and pay the $0.0005 USDC fee via x402?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
