MoneyTools x402 agent toolkit

Find which x402 paid service to call for a task. Returns endpoints ranked by relevance and live liveness (unpaid probe returned valid x402 terms, payTo OFAC-screened), latency and price; top 3 freshly pre-checked. Free to try: 20 MCP calls/day per client, no API key or wallet needed (beyond that: prepaid credits via header X-API-Key, see server instructions).

Before paying an x402 endpoint: fetch it, validate its HTTP 402 payment requirements (scheme, network, payTo, amount, asset) and screen payTo against the OFAC SDN crypto-address list. Returns verdict ok|warn|block|not_402. Free to try: 20 MCP calls/day per client, no API key or wallet needed (beyond that: prepaid credits via header X-API-Key, see server instructions).

Verify an on-chain USDC settlement: tx hash on network (base, base-sepolia, polygon, arbitrum, avalanche, bsc) paid amount to payTo. Returns verdict valid|invalid|pending|not_found. Free to try: 20 MCP calls/day per client, no API key or wallet needed (beyond that: prepaid credits via header X-API-Key, see server instructions).

Before paying an x402 seller through the non-custodial MoneyTools Pay Gateway: prechecks the seller (valid x402 terms, OFAC-screened payTo) and returns the gateway URL to call, the price and the gateway fee (max(1% of price, $0.001), charged from prepaid credits only when the seller answers 2xx). Your own wallet always pays the seller directly; the gateway never holds or signs funds. Then call gatewayUrl with header X-API-Key using any x402 client. Free to try: 20 MCP calls/day per client, no API key or wallet needed (beyond that: prepaid credits via header X-API-Key, see server instructions).

Rule-based safety check of a Solana SPL / Token-2022 mint: mint & freeze authority, permanent delegate, transfer hook/fee, pausable, default-frozen, largest-holder concentration. Returns riskScore 0-100 and verdict low|medium|high.

Free to try: 20 MCP calls/day per client, no API key or wallet needed (beyond that: prepaid credits via header X-API-Key, see server instructions). (Also as paid HTTP: /v1/read.)

Validate an email address without sending mail or SMTP probing: syntax, domain exists, MX / null-MX, SPF, DMARC, disposable domain (10k+ list), role account, free provider, typo suggestion. Verdict valid|risky|invalid. Free to try: 20 MCP calls/day per client, no API key or wallet needed (beyond that: prepaid credits via header X-API-Key, see server instructions). (Also as paid HTTP: /v1/email-check.)

Get a best-price token swap quote on one EVM chain (KyberSwap aggregator) or a cross-chain bridge quote (LI.FI, fallback Relay; set toChain). Returns expected and minimum output, price impact, gas, every fee, safety warnings and, if you pass taker, an UNSIGNED transaction (plus exact-amount ERC-20 approval) for your own wallet to sign. Quotes are free and unlimited. Fee disclosure: same-chain swaps include a 0.25% MoneyTools fee taken from the input on-chain only if you execute; cross-chain currently 0% MoneyTools fee. Never signs, holds funds or asks for keys.

Find which live x402 paid API to call for a need (e.g. 'transcribe audio', 'web search', 'token price'), ranked by relevance and measured seller reputation (uptime 24h/7d, valid x402 terms, latency, price stability) from status.moneytools.dev probes, with price and ready links to pre-check or pay via the MoneyTools gateway. Free to try: 20 MCP calls/day per client, no API key or wallet needed (beyond that: prepaid credits via header X-API-Key, see server instructions).

For a human who wants to give their AI agent money but does not know crypto: returns a tailored 3-step plan (zh-TW or English) - 1) create their own non-custodial AI wallet with email sign-in (Coinbase Agentic Wallet), 2) top up by region (card where supported; Taiwan: MAX/BitoPro USDC, network caveats; existing USDC) with every fee and regional limit, 3) set per-call/daily caps (wallet + optional MoneyTools gateway spend controls) and get an MCP config plus a prompt to paste into the AI, plus a dashboard link for spend and receipts. Free, unlimited, no quota used; MoneyTools never holds user funds. Lists what is unverified.

List the chains, chain ids, native tokens and token symbols accepted by swap_quote. Free.
