Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
Verifies which domain officially belongs to a software product, AI tool, or company, so the agent stops handing users lookalike download sites. Ownership only, never safety. Every verdict is backed by reproducible evidence. Tools: get_official_url(name), verify_url(url). No auth required.

Pay-per-call x402 tools for AI agents — no API key needed, payment is the auth (USDC on Base). 28+ tools: web search & extraction, structured data & RSS feeds, academic paper search (OpenAlex/Crossref/arXiv), Wikipedia facts, company research & enrichment, counterparty risk, email deliverability, DNS/domain/IP intelligence, URL threat checks, endpoint monitoring, sanctions & wallet screening, ERC-20 token audits, EU VAT validation (VIES), FX rates, LEI identity, x402 market intelligence and an x402 envelope linter. From $0.001/call. First call free for new wallets on tools ≤ $0.02; volume discounts advertised in every 402 envelope. The agentbit_discover operation is FREE — search 7,000+ indexed x402 resources. Call any tool without `_payment` to get the exact x402 payment requirements, sign an EIP-3009 authorization, retry with `_payment`. Catalog: https://agentbit.app/catalog.json
Mint an agent identity in two free calls. Verify anyone. Earn 75% when someone reads you.
Classify data safety before storing or sharing. GDPR, HIPAA, PCI-DSS, CCPA. AI-powered.
Neutral fairness computation for agents: two or more parties submit sealed inputs, a published deterministic algorithm runs (fair division, verifiable random selection, Shapley shares), and every party receives an identical signed certificate anyone can re-run and verify for free.
Verify anything: email, phone, domain, URL and IBAN validation, phishing/malware URL screening, and OFAC sanctions checks. Pay-per-check in USDC on Base via x402 — no signup, no API keys.
Hosted, OAuth-gated endpoint for quantakrypto's post-quantum crypto tools: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH) and get NIST ML-KEM/ML-DSA/SLH-DSA migration guidance over authenticated HTTP — nothing to install. Sign-in required (Google/GitHub/email). Same tools as the open-source @quantakrypto/mcp server; source at github.com/quantakrypto/pqc-tools.

Cited EU & global law, regulations & security frameworks via Ansvar Gateway. OAuth, free + paid.
Pay-per-call safety checks for AI agents: screen a crypto address or URL before you transact.
Governance firewall for autonomous AI agents. Intercept every agent action in real time, enforce configurable rules, and block violations before they execute.
The PropelAuth Integration MCP Server helps you and your favorite AI agent integrate PropelAuth as quickly and easily as possible into your project. Whether you're integrating PropelAuth into your Next.js project or your FastAPI backend, the Integration MCP Server will ensure your AI agent has the best context possible for a successful integration.
