How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

Output

Returns the encoded or decoded text as a string. For JWT decode, returns the header and payload claims as parsed JSON (signature is never verified). The original input is never logged or echoed back for JWTs.

Example use cases

Inspect JWT token claims

“I have this JWT and I just want to see what's inside it — decode it for me without worrying about the signature: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIn0.signature”

URL-encode a query parameter

“URL-encode this string so I can safely put it in a query parameter: 'hello world & goodbye/world?foo=bar'”

Convert punycode domain to unicode

“Convert this punycode domain back to its readable unicode form: xn--n3h.xn--nxasmq6b”

When to prefer

Use this endpoint when you need a quick, pay-per-call text encoding or decoding utility without standing up your own library — especially useful in agent pipelines that need to inspect JWTs, sanitize URL parameters, or handle multi-format data interchange. Prefer it for one-off conversions across a wide variety of codecs (base64, hex, URL, HTML, ROT13, punycode, IDNA, quoted-printable) without needing a full SDK.

Side effects

Invalid codec name returns a 400 error
Attempting to encode a JWT (direction=encode with codec=jwt) is not supported
Text exceeding 100,000 characters is rejected
Malformed base64/hex/JWT input that cannot be decoded returns an error
Punycode/IDNA decode of invalid input returns an error
