Endpoint

POSThttps://agent402.tools/api/hex

When to prefer

Use this endpoint when you need a simple, reliable hex encode or decode operation on a text payload up to 100KB, especially within an x402 micropayment workflow where the cost per call is known ($0.001 USDC). Prefer this over rolling your own conversion when you need a quick remote utility call.

Side effects

Input text exceeds 100KB limit — request rejected
Invalid mode value (not 'encode' or 'decode') — may default to encode or return error
Malformed hex string passed in decode mode — returns error or garbled output
Missing text field — returns validation error
Payment not included or insufficient — 402 Payment Required response

Input

{
  "mode": "encode",
