Bazaar quality in Delx benchmark
Historical price floor: Delx was listed at 0.002 USDC; ForgeMesh was at the observed 0.001 USDC floor. Xona listed 0.01 and AgentUtility 0.05 in this readback. These are historical listings, and Delx speech is currently suspended.
Observed activity: ForgeMesh base showed 5 payers versus Delx's 2. Delx led this snapshot on calls (224). Those Bazaar fields do not establish delivered sales. The former Delx route did not offer custom voice cloning.
Historical Delx request shape: supported native text or OpenAI-shaped fields (input, model, voice, response_format, speed). This documents the former contract and does not make the route available for purchase.
