{"method":["One snapshot of OpenRouter’s public, keyless API on 2026-10-06: the model list and the endpoint list of 27 curated models (28 requests). Prices, context, quantization and uptime are copied as the API reported them; a field it did not return stays empty.","Tier: read from the endpoint tag suffix. Flex, priority, fast, ultrafast and batch are named tiers; a region suffix (us, eu, europe, a cloud region) is regional; anything else is standard. This is a heuristic.","Per-model charts show the standard tier only, with one bar per provider: its cheapest standard endpoint. The endpoint table lists every endpoint in every tier.","Blended price = (3 × input + output) ÷ 4, a 3:1 input:output token mix. Spread = most expensive ÷ cheapest blended price among standard-tier providers. Both are calculations on reported prices.","Markup = OpenRouter list price ÷ first-party list price − 1. First-party prices are the vendors’ published list prices as recorded in the product price table. The effective markup adds the credit-purchase fee for card purchases on the Standard plan.","Gateway delay (time to first token, total time, billed cost per call): not measured: no key in the environment. A live harness is ready; it sends nothing without a key and has a hard spending cap."]}
