x402
Agent402 UK Base64 Encode/Decode is a paid API for AI agents from agent402.co.uk, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Deterministically encodes text to Base64 or decodes Base64 strings back to text, safe for headers, JWT fragments, and binary transport.

How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
A JSON object containing the original input text, the action performed (encode or decode), and the resulting encoded or decoded string — e.g. {"text":"hello","action":"encode","encoded":"aGVsbG8="}.
Example use cases
JWT fragment decoding mid-task
“Can you decode this base64 JWT payload for me: eyJ1c2VySWQiOiAxMjM0LCAicm9sZSI6ICJhZG1pbiJ9 — I need to read what's inside without mangling any bytes.”
Encoding API credentials for auth headers
“I need to base64-encode the string 'myuser:mypassword' so I can put it in a Basic Authorization header — make sure the padding is correct.”
Decoding a base64 config value
“This config value came back as base64: aGVsbG8gd29ybGQ= — can you decode it back to plain text for me?”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/utils/base64When to prefer
Use this endpoint when an agent must not guess or hallucinate Base64 padding, especially mid-task with JWT fragments, HTTP Authorization headers, or binary-safe transport payloads. Prefer over LLM-generated Base64 for any production scenario where byte-perfect correctness is required. Priced at $0.001 USDC per call via x402 protocol.
Side effects
- Invalid base64 string passed for decode action (malformed padding or illegal characters)
- Missing required 'action' field returns an error
- Missing required 'text' field returns an error
- Non-UTF-8 binary content may not round-trip cleanly through the text field
