xpay scored OpenAI 81 / 100 on its Agent-Ready SaaS Index, which places it in the Agent-Ready Verified band. Based on public pricing signals, xpay verified that OpenAI publishes per-million-token rates for every model on a public anonymous page (e.g. GPT-5.4 at $2.50/$15 input/output) with self-serve PAYG checkout, no minimum, and an open documentation portal. Enterprise Scale Tier and Reserved Capacity remain sales-led, and xpay could not locate a /.well-known/ai-pricing.json or anonymous one-shot purchase path for non-account agents. For the full 6-step purchase simulation and the one-line fix that would lift this listing into the next band, see the linked scorecard.
