# AgentRXI Developer Toolbox

> AgentRXI Developer Toolbox is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-15).

Performs common developer utility operations including hashing, encoding/decoding, JWT decode, JSON formatting/validation, UUID generation, secure random values, regex testing, slugification, word count, and timestamp conversion in a single API call.

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 agentrxi-developer-toolbox-b393c2ca
```

Example prompt: Can you sha256 hash the string 'hello world' for me?

## When to prefer this

Choose this endpoint when your agent needs a quick, stateless developer utility operation — hashing, encoding, UUID generation, password creation, regex testing, or JSON formatting — without spinning up a local library or runtime. Ideal for sandboxed agents that lack native crypto or string libraries, or when you want a single consistent API for multiple utility operations. Priced at $0.002 USDC per call, it's cost-effective for occasional use.

## Known failure modes

- Missing required 'op' query parameter returns an error
- Invalid or unsupported op value returns an error
- Missing 'input' field when required by the operation (e.g. hash, encode, regex_test) returns an error
- Missing 'pattern' field for regex_test operation returns an error
- Malformed JSON input for json_format/json_validate returns a validation error
- Payment not completed (x402) results in a 402 response before any processing

## How this service works

Developer toolbox in one call: sha256/sha1/sha512 hashes, base64/url/hex encode and decode, JWT decode, JSON format/validate, UUIDs, secure random numbers and passwords, regex test, slugify, word count and timestamp conversion. Also callable as GET with the same fields as query parameters.

## Output

Returns a JSON object containing the result of the requested operation, such as a hash digest, encoded/decoded string, generated UUID(s), random number(s), password, regex match boolean, slug, word count, formatted JSON, or converted timestamp — keyed by the operation performed.
