About code402.dev

code402 is a non-custodial, per-call paid API for deterministic validation and on-chain intelligence: business identifiers (IBAN, LEI, VAT, SWIFT/BIC and more), rental due-diligence, and Base-chain lookups. No accounts, no API keys — calls are paid via x402 (EIP-3009 gasless TransferWithAuthorization, USDC on Base), with a free tier for evaluation and signed XDR-1 receipts for every response.

Principles

• Zero custody. Payment moves payer → operator directly on-chain; the service never holds funds.
• Measured, never declared. Latency and volume figures come from live telemetry, not marketing.
• Deterministic tools. Structure and checksum logic, no scraping, no hallucination surface.
• Public pricing. Per-call prices are quoted live in every 402 challenge and on /pricing.

Operator

code402 is operated by JUANA LIMITED (UK company no. 14043409, Coventry). Legal terms on /terms, privacy on /privacy, security disclosure on /security.
