Cryptographic trust verification APIs

This cluster consists of APIs that evaluate system or API-key trustworthiness using cryptographic proofs and policy rules, returning signed accept, pending, or reject decisions. Only three dated entries exist before the index start, too few to discern a timeline shape, indicating the cluster predates the index or members are largely undated. Traction leaders are stage316, stage315, and stage312, each with 0 stars, suggesting early-stage or minimal activity.

Entry timeline

ENTRY TIMELINE

APR 2026: 1MAY 2026: 2
APR 2026MAY 2026

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 3 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

  1. 01stage3160★5 mo—Monetized API that evaluates a system's trustworthiness using cryptographic proofs and returns accept, pending, or reject decisions.
  2. 02stage3150★5 mo—API that evaluates target systems and returns verifiable accept, pending, or reject trust decisions with cryptographic signatures.
  3. 03stage3120★5 mo—Trust verification API that uses Sigstore signatures and policy rules to assess API key authenticity and trustworthiness.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
