ddg-router

A local OpenAI-compatible proxy that auto-pays x402 and forwards to DDG Agent-Payable Services. It's the piece that lets any agent runtime use DDG as its default provider — a plain OpenAI client can't sign the 402 itself; this can.

pip install ddg-router
ddg-router                       # free-trial mode, no wallet, on :4020
# or, for unlimited paid:
DDG_PRIVATE_KEY=0x<funded Base USDC key> ddg-router

Then point any runtime at it:

base_url = http://127.0.0.1:4020/v1

GET /v1/models and /v1/model-catalog are free; POST /v1/chat/completions, /v1/embeddings, and any DDG tool route auto-pay via x402. GET /healthz for status.

Env: DDG_AGENT_ID, DDG_PRIVATE_KEY, DDG_ROUTER_PORT (4020), DDG_UPSTREAM.
