Ed25519-signed ground-truth oracle — 63 paid x402 tools live on Base mainnet.
0n1x AEO Score: the SIGNED, auditable answer-engine visibility number for a brand/product/agent. Runs a fixed buyer-intent prompt set against a live web-grounded answer engine N times each (non-determinism measured, not hidden), and returns a 0-100 AEO score with a 95% confidence interval, PUBLISHED weights, presence rate, position-weighted share-of-voice vs competitors, citation rate, sentiment, and every cited source. Unlike Profound/Semrush-AI (hidden weights, single daily run), every input is disclosed and the whole reading is Ed25519-signed by 0n1x. Never fabricated. (price: $0.50 USDC, tier: premium)
Signed Agent-Economy Index — the neutral referee for how big the agent economy REALLY is, by segment. Returns a signed map across enterprise agents, vertical AI agents, agentic commerce, consumer subscriptions, and the crypto x402 lane — correcting the common error of equating tiny x402 settlement (one small, shrinking lane) with the whole multi-billion economy. Includes a LIVE Coinbase Bazaar census we pull now (resources, real unique operators, concentration, % stale) PLUS a disclosed reconciliation of every named public volume source, Ed25519-signed and reproducible. Use before citing any agent-economy number in a deck, report, or decision. (price: $0.25 USDC, tier: premium)

Signed verified-registry audit. Fetches a public A2A agent registry (default a2aregistry.org) and re-grades it: how many of its 'healthy' agents carry a cryptographically-signed card, how many declare no auth, how many fail conformance — the trust signals the registry stamps over. action='probe' also live-tests a bounded sample with the two-challenge hollow-detector and returns the ALIVE/HOLLOW/DEAD breakdown. Ed25519-signed, timestamped, recomputable. Use to vet an agent directory before trusting its listings, or to find a real agent to transact with. (price: $0.05 USDC, tier: metered)
