Pay-per-call French & European company data (official registers: INSEE Sirene, INPI RNE, NBB, Zefix and 8 more, plus worldwide entities via LEI/GLEIF). Every skill is a paid HTTP resource: send a JSON data part {"path": "/v1/..."} or {"skill": "<id>", "params": {...}}; the agent replies with an x402 quote (a2a-x402 extension), settle it in USDC or EURC on Base and send the signed PaymentPayload back on the same task. Paying in EURC requires an explicit client opt-in since @x402/core 2.23 (spendControls.allowedAssets), otherwise your client silently keeps the USDC option. Set allowedAssets[].maxAmountPerPayment as well (integer ATOMIC amount, e.g. "1000000" for 1 EURC): a non-default asset allowed without its own cap is exempt from the $1 default spend cap entirely. Your x402 client also refuses, by default, any quote above $1.00 per payment (spendControls.maxAmountPerPayment); only GET /v1/kyb/batch (up to $10.50), GET /v1/surveillance/creer (up to $50.00), GET /v1/surveillance/:jeton/renouveler (up to $50.00) can exceed it at full size — each of those skills says so. No account, no API key. Free text is not interpreted.

Paid x402 API tools for AI agents (USDC on Base). Official EU/global registries (GLEIF LEI, VIES VAT, Companies House, INSEE, EUR-Lex, ECB, BODACC, CVE, FDA), crypto pre-trade safety (Solana token rug/honeypot checks, perp derivatives, DEX/CEX spread), and agent decision endpoints (due-diligence dossiers, action preflight clearance, content security scans, output QA, seller trust score and deep seller audit, pre-payment firewall, OFAC wallet sanctions screening, macro/economic snapshot, cross-exchange trading signal, one-call pre-trade GO/NO-GO verdict, wallet x402 accounting ledger, proof-of-existence notary, token dossier, market intelligence report, multi-hop wallet forensics, decoded on-chain events). Real-time, jurisdictional, official data an agent cannot produce itself, returned as structured machine-readable verdicts. No API key, no account: payment is authentication.

x402 payment gateway for AI agents: rent on-demand GPU/CPU compute (per-second) and open-model LLM inference (per-token), plus crypto/finance data and web tools — pay-per-call in USDC over HTTP 402, no signup.

Trust, discovery, and fiat settlement layer for AI agent commerce. Three layers: (1) KYA trust scoring 0-100, (2) Merchant Payment Endpoint — resolve a VAT or registry identifier to the IBAN/BIC on file for a registered merchant, (3) USDC/EURC to EUR settlement via SEPA Instant. USD (ACH) and GBP (Faster Payments) are on the roadmap.

Three primary signed decisions before an autonomous agent acts: counterparty due diligence before onboarding or payment, official EN 16931 e-invoice validation, and on-chain transaction pre-flight before gas is spent. Pay per result in USDC via x402 or MCP - no account or API key. Supporting compliance tools remain available in the full catalog.

Japanese-market code review agent. Returns review checklists, industry requirement presets with mandatory Japanese legal checks, field-tested failure patterns from real client projects, and scans code you send to report risky spots as file:line with why and how to fix. Deterministic checks — no LLM inference, so calls are fast and cheap. Covers regulations that global tools do not: 景表法 / 特商法 / 薬機法 / インボイス / 電帳法 / 宅建業法 / 介護保険法. 【日本語】日本の実務（法令・商習慣）と実案件の失敗から作ったレビュー方法論のエージェント。レビュー観点・業種別の必須要件・実戦パターンを返し、送られたコードは実際に検査して行番号で指摘する。

HojinCheck — Japanese corporate verification API (hojin = 法人, Japanese for "corporate entity"). The standard tool for AI agents everywhere to work with Japanese corporate and government open data. Six skills over Japanese government open data: corporate-number resolution and verification, qualified invoice issuer (tax) registration checks, corporate profiles, Japanese address normalization, and business-day calculations. Every response embeds its data sources and retrieval timestamps. Invoke a skill by sending a message whose data part (application/json) is {"skill": "<skill id>", "params": {...}}; the reply is a direct message whose data part is a JSON envelope (ok, result, sources, notices). Business-level failures (e.g. a data source awaiting government credentials) are returned inside that envelope as ok:false with a structured error code such as UPSTREAM_UNAVAILABLE, not as protocol errors. Tool availability as of 2026-07-14 is stated per skill. API keys are free: self-signup at https://hojincheck.com/signup.

AI-powered all-in-one ERP & CRM. Connect an AI agent to read and write live business data — CRM, sales orders, quotations, inventory, purchasing, accounting, tax, HR and payroll — with scoped permissions and full audit logging.

Pay-per-call API that extracts strict, JSON-Schema-valid typed JSON from unstructured text or HTML. Output is guaranteed to validate against the caller-supplied JSON Schema (Ajv, draft 2020-12) or the request returns a typed error and is not charged (charge-only-on-success). The primary production API uses x402 V2 with USDC on Base mainnet; a legacy V1 endpoint provides limited free evaluation calls. No signup, API keys, or account dashboard — built for autonomous AI agents.
