One request. N genuinely different options.

The Variants API returns N distinct, catalog-grounded output variants per request. Every item in every variant resolves against your catalog, and every response carries a receipt.

What it is

Riley Routes is a business-to-business API: a customer sends one request and receives several genuinely different, catalog-grounded options for their end user, plus a verifiable usage report.

How it works

  1. Send one request. Include your catalog inline; your data stays in the request.
  2. Receive N variants. Each one genuinely different, each item resolved against your catalog.
  3. Read the receipt. Every response records what was requested, what was verified, and anything withheld.

The bundle

Distinct by design

Ask for five options and get five options, not five paraphrases of one idea.

Fail-closed grounding

Every identifier in every variant resolves against your catalog. If an item cannot be verified, the option is withheld rather than invented. Wrong data is worse than no data.

Receipts on everything

Every response ships with a per-generation receipt, and a baseline report measures the input-token efficiency ratio on your workload, not asserted from ours.

Measured, not asserted

Measured at 2.6 to 2.8x input-token efficiency versus N independent calls in Riley Routes reference measurements. Separately, reference measurements show approximately 25 to 28 percent workload cost reduction per comparison set (Anthropic basis: 27.5 percent, rate-clean; Gemini basis: 24.82 percent per-generation average and 24.61 percent across 60 matched pairs).

Efficiency figures apply to stacks without shared-prompt multi-sampling and to workloads without cacheable shared prefixes. Your baseline report measures your own case.

Demos

The Variants API is not specific to any industry. It works wherever a product needs to offer several genuinely different options drawn from a catalog you already own.

Travel demo

A reference demonstration of the Variants API on itinerary options.

Finance demo

A reference demonstration on financial plan options. A method demonstration, not investment advice.

Architecture demo

A reference demonstration on cloud architecture options. A method demonstration, not architecture or procurement advice.

Live walkthroughs of the demos are available on request during the private beta.
