 # RIP-01: OpenAI-API Proxy with Cashu Payments
 
-[x] - Implement HTTP proxy interface for OpenAI-compatible API requests
-
-- [x] Integrate per-request micropayment handling via Cashu tokens
-- [x] Support endpoints:
-  - [x] POST /v1/{path:path} (proxy to upstream AI service)
-  - [x] GET /v1/wallet (get Cashu token balance and API key)
-  - [x] POST /v1/wallet/topup (top up wallet with Cashu token)
-  - [x] POST /v1/wallet/refund (refund remaining balance as Cashu token)
-- [x] Authorization via Bearer API key or Cashu token
-- [x] API key and Cashu token validation and redemption
-- [x] Token-based pricing for chat/completions with MODEL_BASED_PRICING
-- [x] SSE and JSON cost reporting in responses
-- [ ] Tor hidden service deployment support
-- [ ] Admin dashboard for monitoring and settings

 Each node can serve multiple models.
 These models are defined in the root `/` endpoint.
 Including node information and pricing.

+## Upstream API
+
+The upstream API is defined in the `UPSTREAM_BASE_URL` environment variable which is authenticated using the `UPSTREAM_API_KEY` environment variable.
+
+Optional the proxy can attach multiple upstream APIs and route using a algorithm to other proxy providers that list their node on nostr.
+
+## X-Cashu Header
+
+Every proxy supports X-Cashu headers as payment protocol. Instead of authenticating using the Bearer API Key header a valid cashu token can be send in the 'X-Cashu: cashuBxxxxx' Header which is then claimed, and a refund is send in the same X-Cashu Header inside the response with the change balance.
