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.
STIX IOCs, CVE lookups w/ EPSS/KEV, ATT&CK dossiers, OFAC wallet sanctions, domain age checks.
Prove end users to agents and apps: login-links, OIDC clients, and API keys over remote MCP
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).
Website monitoring: list sites and checks, run scans, read results and fix prompts.
Check a document for hidden text before your agent reads it. PDF, Office, RTF, HTML.
Website monitoring for any site, deepest on WordPress & WooCommerce: list sites and checks, run scans, read results and get fix prompts.
Entity verification, sanctions screening, and trust scoring for AI agents via x402 micropayments.
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.
Trust gate for AI agents: multi-model adversarial consensus, signed and verifiable verdicts.

Scan text, documents, websites, and MCP metadata for prompt injection and sensitive-data risks.
Technology intelligence feed for AI agents: tech stack, compliance, security.
Pre-execution policy gate for consequential agent actions with durable trust receipts.
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.
Trust infrastructure for AI agents: check reliability, verification, and trustDecision by URL.
