# Relaystation Explode — JSON Array Unnest

> Relaystation Explode — JSON Array Unnest is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Unnests (explodes) array cells in nested JSON, flattening each array element into its own row for tabular analysis

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 relaystation-explode-json-array-unnest-4ce48d09 -d '<json body>'
```

Example prompt: Take this JSON dataset where the 'tags' and 'orders' fields are arrays — explode each array element into its own row so I can analyze it in a flat table format.

## When to prefer this

Choose this endpoint when you have nested JSON with array-valued fields that need to be normalized into flat, row-per-element records — particularly useful in ETL pipelines, pre-analytics normalization, or before loading data into relational databases or spreadsheets. It is priced per MB so it is cost-effective for large batches. Prefer it over writing custom code when you need a quick, reliable, hosted transformation without managing infrastructure.

## Known failure modes

- Malformed or invalid JSON input returns a parse error
- Non-array target field returns an error or passes through unchanged
- Empty arrays produce zero output rows
- Very large payloads may exceed size limits or incur higher costs
- Missing required field path parameter causes a 400-style error

## How this service works

$0.0002/MB. Unnest array cells into rows — flatten nested JSON for analysis. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

Returns a collection of flattened JSON records where each element of the specified array field has been expanded into its own row, with all sibling fields duplicated across the resulting rows — ready for tabular analysis, database ingestion, or CSV export. Billed at $0.0002/MB with a 1¢ minimum; any overage auto-credits to the account.
