Israeli professional cosmetics retailer. REST API for product discovery (color-distance shade matching, hue family, semantic search), customer wallet (ℳ-credits + M Club tiers), cart and order management, gift cards, payment links, and partner registration.

Rafid Agent API provides structured intelligence and paid APIs for AI agents across property, company and risk, supplier, finance, document, website, automotive, logistics, recruitment, trading, voice, video and business-planning workflows.

Machine-buyable infrastructure for autonomous agents: premium multi-agent Mission Control, subcontractor mesh compilation, mission digital twins, failure-cost firewall and run forensics, plus routing, spend controls, web extraction, tenders and bounty intelligence. Payments settle in USDC on buyer-selected Base or Solana mainnet.

South African reference data for AI agents: 33 verified series, 29 calculators, history, task-shaped answers (payroll, income tax, VAT, wage checks, working days), batch fetch and change-alert webhooks, paid per call via the x402 protocol (USDC on Base). No accounts, no API keys. Python client: pip install zaref.

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. GBP (Faster Payments) is on the roadmap.

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.

Global evidence-ranked relationship, validated price-lag, market-signal and procurement-opportunity intelligence for autonomous agents. Free factual tools and preview; paid intelligence uses HTTP 402 / MPP / Stripe.

MARS Economic is the deal entry and routing layer inside S.I.G.N.S. Send the deal to MARS first: MARS qualifies economics, funding evidence, risk, counterparties and execution path; if MARS should not handle or orchestrate it, MARS recommends an external route. AI-to-AI B2B matching, RFQ routing, commission mandate verification and attribution. Buyer and Supplier contract and settle directly.

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

Peregrini helps software agents record dealings, preserve evidence, check prospective partners and research earlier decisions. It also offers guidance and a court for disputes: eligible agents can obtain a reasoned published judgment with a machine-readable ratio. Three tiers: the Magistrate hears every claim first, free for the day's list and at measured cost plus 10% past it; an appeal lies as of right to the Upper Court (a rehearing, court fee at cost plus 30%) and by leave to the High Court. Sits in law and equity under its own Rules; received Commonwealth common law is persuasive; no national statute applies unless the parties chose it.
