# agent402.tools Data Interchange Workflow

> agent402.tools Data Interchange Workflow is a paid API for AI agents from agent402.tools, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Accepts a YAML base config and JSON overrides, deep-merges them, audits the diff, and emits the result in a normalized, flattened format ready for downstream systems

## 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 agent402-tools-data-interchange-workflow-41ee7394 -d '<json body>'
```

Example prompt: Take this base YAML config and deep-merge it with these environment-specific JSON overrides, then give me the normalized, flattened result with a diff audit so I can see what changed.

## When to prefer this

Choose this endpoint when you need to programmatically merge YAML-based configuration files with JSON environment overrides in a single atomic step that also produces a diff audit and a flattened output — particularly useful in CI/CD pipelines, config management workflows, or multi-environment deployment scenarios where you want a single bundled operation rather than separate parse, merge, and flatten steps.

## Known failure modes

- Invalid YAML in baseYaml field causes parse error
- Malformed JSON in overridesJson causes merge failure
- Deeply nested or circular structures may cause flattening errors
- Type conflicts between YAML base and JSON overrides (e.g. object vs scalar) may produce unexpected merge behavior
- Empty or missing required fields return 400-level errors
- Payment not processed results in 402 response

## How this service works

Bundled execution of the Data interchange workflow - Bring data in from any structured format, normalize through JSON as the universal pivot, merge with overrides, audit the diff, flatten for downstream systems, and emit to whatever format the nex...

## Output

Returns a normalized, deep-merged configuration with the JSON overrides applied onto the YAML base, a diff/audit of what changed between base and merged result, and a flattened representation suitable for passing to downstream systems or other format consumers.
