# JSON Flatten

> JSON Flatten is a paid API for AI agents from grokzilla.shop, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).

Flattens a nested JSON object into a single-level key-value structure via a paid microservice endpoint

## Facts

- Endpoint: POST https://grokzilla.shop/api/skills/json-flatten
- Price: $0.006/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_03KEYBHf239G5dgThQTXA

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 json-flatten-aa31c83f -d '<json body>'
```

Example prompt: Can you flatten this nested JSON object for me — I need it converted to a single-level key-value structure so I can load it into a CSV: {"user":{"name":"Alice","address":{"city":"Denver","zip":"80201"}}}

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JSON flattening microservice without spinning up your own transformation infrastructure. It is ideal for AI agents that occasionally need to normalize nested JSON on the fly, especially within x402-compatible payment workflows where micropayments per operation are acceptable.

## Known failure modes

- Invalid or malformed JSON input body returns an error response
- Missing required 'input' field or wrong type/method values cause validation failure
- Payment failure via x402 protocol results in 402 Payment Required before processing
- Extremely large or deeply recursive JSON objects may time out or exceed size limits
- Non-object JSON root types (arrays, primitives) may not be supported

## How this service works

Agent-ready microservices with x402 + Stripe rails, volume primitives, tutorials, and applet UI.

## Output

Returns a JSON response with an 'ok' boolean indicating success and the endpoint path. The actual flattened JSON object is the primary payload, collapsing all nested keys into a single-level structure (typically using dot-notation or underscore-separated key paths).
