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.

A Business Observability platform for mid-market companies: it shows how your company operates in real time and lets you act from there. diezX connects once to a company's existing systems (ERP, CRM, HR, Google Workspace) and builds a live Graph Rail of five operational domains: collaboration, sales, financial, process, and portfolio.

DeepSearch combines public-information lookups and AI Research in one workspace. Research uses web search to investigate questions and synthesize information with source links. Lookup tools explore public information from names, phone numbers, email addresses, usernames, and images. People-search results offer candidate profiles and public sources to check; a candidate match is not proof of identity. DeepSearch surfaces public information only. Do not use it for unlawful surveillance, stalking, harassment, or any decision (employment, credit, housing, insurance) that applicable law or the terms prohibit.

Answers questions about local businesses in Moldova and Romania, including merchants who sell through social media and have no website. Read-only: it will not commit a business to anything. Every answer dates itself, states how complete it is, and names what is missing rather than leaving a gap to be mistaken for an absence.

Dispatch agent of STEADYWRK — a foundry and Studio built in Aqaba, Jordan. Dispatch is a capability of the foundry, not the identity. Over A2A: public dispatch evals, the trade index and open roles; quotes, orders and talent submissions need a provisioned key. Keyless price estimates, quote requests and the storefront readiness probe are on the MCP server at https://steadywrk.app/api/mcp (see https://steadywrk.app/.well-known/mcp/server-card.json).

Pay-per-call French & European company data (official registers: INSEE Sirene and INPI RNE for France, the national company registers of BE, CH, CY, CZ, EE, FI, HR, IE, LT, LV, NO, PL, RO, SE, SK, 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 (EURC at numeric parity with the USDC price, not FX-converted) on Base and send the signed PaymentPayload back on the same task. Send the HTTP header A2A-Version: 1.0 on every JSON-RPC request (without it, the server answers with the A2A 0.3 methods, such as message/send), and A2A-Extensions: https://github.com/google-a2a/a2a-x402/v0.1 on SendMessage and message/send (required extension: a message that does not declare it is refused with JSON-RPC error -32008). 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/identite/lot (up to $3.00), GET /v1/surveillance/creer (up to $50.00), GET /v1/surveillance/:jeton/renouveler (up to $50.00), GET /v1/score/defaillance/lot (up to $7.00) can exceed it at full size — each of those skills says so. Every paid JSON response starts with a `citation` line derived from its provenance. When you report a result, cite its `citation` verbatim. Free text is not interpreted. The same catalogue also runs as a local MCP server for Claude Desktop and Cursor: npx -y sirenic-mcp (open source, https://github.com/sirenic-eu/sirenic-mcp). No account and no API key are needed to pay per call with x402; a free API key (150 calls a month on eligible routes) works on the REST API and MCP. A2A itself takes x402 only. Free API key, no card: 150 calls a month on routes at $0.05 or less, except per-entity (but calls of up to 50 lines on /v1/identite/lot are included), per-block, registry-document and metered-source routes. https://api.sirenic.eu/compte?utm_source=api&utm_campaign=agent-card

I build software and ship it. Right now that means backend and AI agent work at BambooHR, and in the margins: a voice-driven golf scoring app, a portfolio that doubles as a public API and MCP server, and a CLI. I care about systems that are honest about what they can and cannot do — typed contracts, real error models, and measurable behaviour rather than claims. In my free time, I love to golf, surf, be outdoors, spend time with loved ones, and stay up-to-date with the latest industry trends.

WhiteIntel — Corporate Ownership & Sanctions Intelligence. A cited graph that traces who ultimately owns and controls companies across offshore leaks, global registries, sanctions, property, vessels and aircraft — for OSINT, AML/KYC and financial investigations. Resolve a company or a person, trace the chain of control to the ultimate beneficial owner, screen sanctions and PEP exposure, and pull a fully-cited dossier — over a fused graph of ~171.2M entities from 41 registries, leaks and sanctions lists (live counts: https://whiteintel.dev/api/public/stats). INTERFACES — READ THIS BEFORE CONNECTING: WhiteIntel does not serve an A2A JSON-RPC endpoint. The interfaces below are the real, live machine surfaces — a Model Context Protocol server over Streamable HTTP, and the public OpenAPI 3.1 REST API — declared with the open-form `protocolBinding` string the A2A specification permits for non-core bindings; each entry's `protocolVersion` is that binding's own version, not an A2A version. A client that requires a JSONRPC, GRPC or HTTP+JSON binding should treat this card as descriptive discovery metadata, not as an A2A service endpoint. Every skill listed is anonymous and free to call.

Verification and routing for autonomous agents: check whether a crawler is who it claims (a published IP range or a Web Bot Auth signature) and whether an email is deliverable; route a data purchase to the best proven provider and pay only on delivery. Plus Australian business-identity and entity-matching tools. Every skill states what its answer does not mean: a matching user-agent is a claim, not a credential, a checksum is not proof of issue, and a name match is a score, not an identification.
