By default the router tries our listings in routing order and fails over before the first byte — never mid-answer. Pin, exclude or order providers with a routing policy. Each provider charges its own price: name one with provider.only and you pay its price; otherwise you pay the price of the provider that serves the request ($1.25 in / $4.25 out per 1M where routing starts, unless it fails over). provider.sort: "price" tries the provider with the lowest input + output price first, and provider.max_price leaves out a provider above your limit. Uptime is our own 24h measurement; a dash means too few requests to measure yet. Open a row for its specs, parameters and policies.
