x402 Utility Tools: Base64 CodecPOST /v1/tools/base64-codec · x402 API by x402-utility-tools

Encode or decode Base64 and URL-safe Base64 text. Low-price deterministic x402 utility bench with CSV, JSON Schema, timestamp, JWT, URL, hash, and text tools at the current $0.001 CDP-compatible floor. Browsers can inspect the quote, but payment requires a buyer-owned runtime that signs and retries the same request with X-PAYMENT. Buyers can download the route-specific first-payment client at https://x402-utils.558686.xyz/x402/route/base64-codec/first-payment-client.mjs, run node first-payment-client.mjs for quote-only checks, then opt into a buyer-owned x402 payment with PAY_REAL_X402=1. Copy-ready first paid request: curl -fsSL https://x402-utils.558686.xyz/x402/route/base64-codec/first-payment-client.mjs -o first-payment-client.mjs && npm install @x402/fetch @x402/core @x402/evm @x402/s
