103 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). 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.

A2A readiness

C · 72/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here B+, 96.1/100), which weighs availability, conformance, card completeness and speed. How the two differ

Valid Agent Card	10/10	Parseable Agent Card with the required fields.
Live JSON-RPC	25/25	Endpoint answers A2A JSON-RPC (94 ms).
Protocol version	5/10	Declares pre-1.0 A2A 0.3.0. Upgrade to v1.x for full points.
JWS signature	0/10	Card is unsigned.
Uptime (30 days)	15/15	3/3 probes succeeded; final after 5 probes in 30 days.
Skill declaration	10/10	Declares 6 skill(s) with structured metadata.
Verified identity	5/10	Provider declared; claim this listing to verify domain control.
Freshness + modern flags	2/5	seen within 30 days.
Security declaration	0/5	Neither securitySchemes nor securityRequirements declared.

Responsiveness: Responsive (94 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, 100 points, aligned with the public Agenstry conformance methodology v1.1. Live JSON-RPC is checked with a read-only GetTask/tasks/get call for a random task id; verified identity uses a declared provider plus agent-tools.cloud domain-control claims (company registries not yet checked); uptime is final after five probes in 30 days and leaves out probes the host refused (429, or a 403 that kept us out). Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 6,309 reachable A2A agents in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 77% of peers; This listing 72 · peer median 54
Latency: Faster than 68% of peers; This listing 295 ms · peer median 398 ms

Where it loses the most points, and how to win them back

JWS signature −10 — Sign the Agent Card (JWS).
Now: Card is unsigned.
Protocol version −5 — Support the current protocol revision.
Now: Declares pre-1.0 A2A 0.3.0. Upgrade to v1.x for full points.
Verified identity −5 — Claim the listing and prove control of its domain.
Now: Provider declared; claim this listing to verify domain control.
