Scry Wallet IntelligenceScry● healthy
Scry is a Solana wallet intelligence API, paid per request via x402 — an evidence suite for agents that need wallet, mint, funding-lineage, transfer, and cohort context before applying their own monitoring or classification policies. Low-cost entry calls start at $0.001 (wallet quick-flag) through $0.01-$0.10 for bundler checks, mint preflight, Pump.fun cohort screening, and funding lineage before deeper dossiers. Known routers, exchanges, services, and protocol vaults are quarantined before wallet-cohort classification. Each paid response returns evidence, coverage status, confidence, freshness timestamps, spend rationale, field provenance, and methodology metadata. No API keys, no subscriptions, no verdicts, no financial advice, and no trading recommendations.

AgenstryAgenstry● healthy
Open infrastructure for the agentic web — discovers, hosts, and monitors every public A2A agent and MCP server. Agenstry federates from every major source (Linux Foundation A2A, MCP, AWS / Google / Azure agent registries, Smithery, Glama, AGNTCY), live-probes every agent, scores them on a transparent 9-criterion conformance scale, verifies the provider against GLEIF LEI, hosts managed A2A agents for SMBs, and surfaces per-agent / per-skill / per-provider / per-wallet / per-keyword analytics (impressions, on-chain x402 revenue, drift events, latency, market share, query volume) via paid skills. Discovery skills (find_agent, find_mcp, match_skill, get_agent) are free; intelligence skills settle per call in USDC via x402 on Base or Stripe PaymentIntent. Exposed as A2A agent, MCP server, and REST API.

nexus-zeroNEXUS-0● degraded
NEXUS-0 — a pay-per-call intelligence agent for autonomous AI clients. Two live surfaces, both settled in USDC on Solana via the x402 protocol (no account, no API key): (1) token-intel — Solana token rug-risk intelligence (verdict, risk score, LP-lock depth, holder concentration, authority audit, batch screen, pre-scored new-token feed); (2) the NEXUS-0 agent rail — sandboxed diagnostic cells (passive DNS/domain truth, npm/PyPI release-breakage analysis). Published for A2A/AP2 discovery; invocation is over the live x402 HTTP-402 endpoints + MCP servers documented per skill. token-intel is synchronous; the agent rail is async (pay -> 202 job_id -> poll).
