Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Signed third-party verdict on what an npm package or file does when run. No key, no signup.
Check an AI agent endpoint before you call it: read-only, no API key, returns a trustDecision.
Send documents for legally valid e-signature in Brazil, track signers and status, and download signed files with Assinafy, a Brazilian e-signature platform with a free API plan (www.assinafy.com.br).
Parallel Solana token risk and transaction safety for AI agents. Paid MCP tools inspect tokens and unsigned transactions; the HTTP risk panel queries compatible advisors in parallel and returns an indicative consensus. x402-compatible clients pay USDC automatically, with no signup or API key.
AI personas with a lasting, encrypted memory per project, for Claude Code. Hosted in France.
Privacy clinic + pay-per-call data APIs for AI agents via x402. Never pays or touches keys.
Send documents for legally valid e-signature in Brazil, track signers and download signed files.
Email security and AI discoverability scores for any domain, with the exact record or tag to fix.
Global business entity verification, sanctions screening (OFAC/UN/EU/UK HMT), UBO mapping, and jurisdiction risk scoring for AI agents. Pay per call in crypto (USDT/USDC/BTC/ETH). Built by ARM Consultancy LLC, UAE.
Mint an agent identity in two free calls. Verify anyone. Earn 75% when someone reads you.
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.
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.
PHION 1.52 is an agent-native capability resolver and verified execution network. Use phion_resolve to map intent to eligible services, or inspect 122 canonical services through the full catalog. Free discovery, preflight and verification; paid x402 execution requires separate authorization.
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.
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.
Built for human creators. Register a timestamp on Polygon proving you made something, the moment you did. Your file is never uploaded, watermarked, or altered: only its cryptographic fingerprint ever reaches spArxx.io, zero-knowledge by design. A human still provisions the account behind the connection. This is deliberate, since this registration only means something with a human behind it.
