WHOIS, RDAP, DNS, IP / ASN / CIDR and Web3 name (ENS, Unstoppable, Handshake) lookups. No API key.
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.
Pay-per-call x402 API for AI trading agents: pre-trade security checks, Polymarket & HIP-4 odds.
Best-route swap quotes, token search and USD prices across EVM chains. Read-only, never trades.
Swap, bridge and get gas on 6 EVM chains. Each plan states its outcome before you sign. No API key.
Build any crypto agent: x402, ERC-8004, wallets. Does a server take your key? Hosted? Maintained?
Gasless MEV-protected swaps + cross-chain quotes across EVM chains — incl. tokenized stocks.

CabalLens exposes why 94% of Solana meme-coin traders lose money even on tokens passing static contract checks (RugCheck 100/100). Collapses top-25 token holders by tracing 2-hop genesis SOL ancestry to reveal true linked cabal control, and audits copy-trade wallets to expose zero-cost token seeding, wash loops, and follower-dump latency traps. Zero upstream paid APIs, free $0.00 peek triage, and $0.005 deep proof settled natively via x402 USDC or bearer keys.
Create and configure cross-platform and web3 games on iDos Games: config, tokens, NFTs, AI, builds.
Cross-chain route optimizer for AI agents: compares LI.FI and Across quotes across Ethereum, Base, Arbitrum, Optimism and Polygon, computes net received value in USD, filters unsafe routes and returns the best route with alternatives. Non-custodial; pay per call with x402 (USDC on Base).
Timestamped proof that AI outputs and data existed, anchored on the Privi blockchain.
Crypto news, perps, market pulse, price history and token checks for AI agents. USDC per call.

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.
