API Adjustmenter

Overview

API Adjustmenter is a practical utility API designed to reduce integration friction when external JSON is inconsistent, over-nested, or structurally unstable.

It is useful when you need to normalize key styles, coerce values into predictable forms, apply reusable transformation rules, or inspect response drift before passing data into automation or AI systems.

What it does

1. Normalize inconsistent JSON

Adjusts key casing, null-like values, type inconsistencies, and other common response irregularities into a more predictable structure.

2. Apply reusable adjustment rules

Supports rule-driven cleanup so the same mapping and transformation logic can be reused across repeated API responses.

3. Surface response drift

Helps identify structural or semantic changes between payload versions, which is useful when third-party APIs evolve without notice.

4. Prepare output for downstream consumers

Produces cleaner JSON that is easier to validate, cache, diff, and pass into automation steps, databases, or LLM tools.

Typical use cases

• Third-party API stabilization before internal system consumption
• LLM JSON cleanup when model output is structurally noisy
• Workflow automation hygiene for Zapier, cron jobs, or serverless steps
• Contract normalization for frontend and backend integration layers
• Schema drift monitoring for brittle upstream providers

Example Request

POST /adjust

Example JSON body:

{
  "input": {
    "UserID": "42",
    "user_name": "Alice",
    "isActive": "true",
    "last-login": null
  },
  "ruleset": "default-normalize",
  "response_level": "standard",
  "include_diff": true
}

Example Response

{
  "result": {
    "adjusted_json": {
      "user_id": 42,
      "user_name": "Alice",
      "is_active": true,
      "last_login": null
    },
    "changed": true,
    "rule_count_applied": 4
  },
  "meta": {
    "status": "ok",
    "response_level": "standard",
    "include_diff": true,
    "diff_summary": {
      "keys_renamed": 3,
      "values_coerced": 2
    },
    "execution_ms": 11.4
  }
}

Exact fields may vary depending on the selected ruleset, response level, and plan.

Why it matters

Integration problems often come from small inconsistencies rather than total outages.

A vendor may change casing, mix strings and numbers, add nested wrappers, or return optional fields unpredictably. Those changes create brittle automation and repeated patchwork in downstream code.

API Adjustmenter helps absorb that instability early so the rest of your stack can work against cleaner, more repeatable JSON contracts.

Quick Start – Python Example

import requests

payload = {
    "input": {
        "UserID": "42",
        "user_name": "Alice",
        "isActive": "true",
        "last-login": None,
    },
    "ruleset": "default-normalize",
    "response_level": "standard",
    "include_diff": True,
}

res = requests.post(
    "https://api-adjustmenter.p.rapidapi.com/adjust",
    json=payload,
    headers={
        "x-rapidapi-key": "YOUR_RAPIDAPI_KEY",
        "x-rapidapi-host": "api-adjustmenter.p.rapidapi.com"
    }
)

print(res.json())
