# Hermes Micro-Agent – Base64 Encode/Decode

> Hermes Micro-Agent – Base64 Encode/Decode is a paid API for AI agents from 92.5.95.177.sslip.io, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-29).

Encodes or decodes Base64 strings via a pay-per-use HTTP 402 micro-task endpoint settled in USDC on Base

## Facts

- Endpoint: POST https://92.5.95.177.sslip.io/base64?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-29
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/hermes-micro-agent-base64-encode-decode-b642344a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_t-6Eh6IDEr0b96T30Jh7a

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability hermes-micro-agent-base64-encode-decode-b642344a -d '<json body>'
```

Example prompt: Can you Base64-encode the string 'username:password123' for me? I need it for an HTTP Basic Auth header.

## When to prefer this

Choose this endpoint when you need a quick, serverless Base64 encode or decode operation and are already operating in an x402/USDC micropayment workflow on Base. It is convenient for AI agents that handle small one-off data transformation tasks without standing up their own compute. For high-volume or free Base64 operations, a local utility or free API is more cost-effective.

## Known failure modes

- Invalid or malformed Base64 input when decoding may return an error string or garbage output
- Missing 'prompt' field causes a 400-level error
- Payment not settled on-chain results in 402 Payment Required with no task execution
- Non-UTF-8 binary data may not round-trip cleanly through the text prompt field
- Ambiguous task selection if 'task' field is omitted and service cannot infer encode vs decode

## How this service works

20 paid AI and data micro-tasks over HTTP 402 on Base (USDC): summarize, extract, keywords, sentiment, translate, rewrite, proofread, python_debug, code_lint, code_explain, code_refactor, code_review, json_minify, json_query, csv_to_json, hash, base64, convert, describe_image, probe_media. Each call is priced per-task and verified on-chain before execution.

## Output

A plain string containing either the Base64-encoded representation of the input text, or the decoded plaintext string if a Base64 value was provided. The response is a raw string, not a JSON object.
