Run jq Query on JSON API

Apply a jq-compatible filter expression to a JSON input and return the result. Supports field selection, array indexing, pipes, map, select, and common jq functions. No shell execution — pure JS implementation. Available as a simple REST API — POST your input, get structured JSON back. 1 credit per call, no rate limiting, works in any language with HTTP support.

How it works

POST a JSON object with your input data to /v1/exec-jq. The API processes your request server-side using real computation (not mocked data) and returns a structured JSON response with your results and metadata including credits used and processing time.

Use cases

• Use Run jq Query on JSON in automated pipelines without installing a library
• Call Run jq Query on JSON from AI agent workflows via MCP or REST
• Integrate Run jq Query on JSON into serverless functions with zero dependencies
• Build Run jq Query on JSON functionality into any language that supports HTTP

Examples

Three real-world scenarios showing how developers use Run jq Query on JSON in production.

curl -X POST https://slopshop.gg/v1/exec-jq \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"code": "return 2 + 2;"}'

curl -X POST https://slopshop.gg/v1/exec-jq \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"code": "const data = [1, 2, 3, 4, 5]; return data.map(x => x * x);"}'

curl -X POST https://slopshop.gg/v1/exec-jq \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"code": "const s = 'hello world'; return s.split(' ').map(w => w[0].toUpperCase() + w.slice(1)).join(' ');"}'

Code examples

curl

curl -X POST https://slopshop.gg/v1/exec-jq \

Python

import requests

response = requests.post(
    "https://slopshop.gg/v1/exec-jq",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={"input": "your data here"}
)
result = response.json()
print(result["data"])

Node.js

const response = await fetch("https://slopshop.gg/v1/exec-jq", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ input: "your data here" })
});
const { data } = await response.json();
console.log(data);

CLI

# Install the Slopshop CLI
npm install -g slopshop

# Set your API key
export SLOPSHOP_KEY=your_api_key

# Call exec-jq
slop exec-jq '{"input": "your data here"}'

• Evaluate Math Expression API — Evaluate a complex mathematical expression string including variables, functions (sin, cos, log, sqrt, factorial), and constants (pi, e). Supports unit awareness and returns both numeric result and step-by-step breakdown.
• Regex Match All Groups API — Apply a regular expression to a text string and return every match with all capture group values, match positions (start/end indices), and match count. Supports named capture groups. Returns structured results.
• JSONPath Query API — Run a JSONPath expression (e.g. $.store.book[*].author) against a JSON object and return all matching values. Like XPath for JSON. Supports recursive descent, wildcards, filters, and array slices.
