# MoneyTools Tools

> Bitcoin fee estimate, EVM gas price, token safety check, token approvals, calldata decoding, DNS/SSL checks: 100+ small, cheap, read-only tools for AI agents: on-chain data and wallet safety (token safety, approvals, tx/calldata decoding, EIP-712 risk, NFT, Safe multisig, contract reads, logs, balances, BTC/Solana), DeFi math (APY, vesting, liquidation, impermanent loss, loans), web/domain checks (HTTP, DNS, SSL, security headers, SPF/DMARC, sitemaps, feeds, broken links, phishing look-alikes), agent-protocol validators (x402, MCP, OpenAPI, llms.txt, A2A), developer/text utilities, validators (phone, IBAN, card Luhn, Taiwan ID), TW/US calendars, and LLM text utilities (token count, LLM cost, RAG chunking, HTML→Markdown, PII redaction, prompt-injection scan, JSON repair/diff/query, safe math). Free tier is on by default, no header needed: 10 free calls per tool per day, capped at 20 free calls per client per day across all tools (anonymous salted hash, no raw IP stored), no key or wallet needed. Over the cap: HTTP 402 with the 1 USDC/30-day all-tools plan (https://api.moneytools.dev/v1/plan/buy?utm_source=agentcard) or per-call x402. Plan/API-key users are not capped by the free tier. Optional: header X-MoneyTools-Free: 1 (or ?free=1) to request free explicitly; header X-MoneyTools-Pay: 1 (or ?pay=1) to always get HTTP 402 + PAYMENT-REQUIRED (x402 v2) and pay. Directory validators/probes (HEAD, no params, X-Probe-402: 1) get the 402. Run by MoneyTools (moneytools.dev). Each tool has a free daily tier; after that it costs the listed price per successful call via x402 (USDC on Base, paid to the MoneyTools team wallet) or 1 prepaid MoneyTools credit. Failed calls are never charged. All tools are read-only: we never sign, send or hold funds or keys. Third-party data (public RPCs, Sourcify, DefiLlama, KyberSwap quotes, LI.FI status, mempool.space, ethereum-lists, Cert Spotter/crt.sh, RDAP, public DNS resolvers, ECB/Frankfurter, ExchangeRate-API, Taiwan government open calendar) is attributed in responses; not financial advice.
