{"instructions":"Phase Router: OpenAI-compatible model router, about 400 models. Send a normal request (for example POST /v1/chat/completions with a model id from GET /v1/models, or model \"auto\") without Authorization: the 402 quotes the price of that request in USDT on Phase L1 (network eip155:1015, scheme upto, the ceiling is the price of the input plus max output tokens; you pay what the answer actually cost). Sign the authorization and repeat the request with the PAYMENT-SIGNATURE header. Many calls in a row: open a payment batch with POST /v1/batches. An API key (Authorization: Bearer phk_...) works instead of x402.
