How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

Output

Returns a JSON object with a 'data' field containing the repaired and valid JSON, a 'status' field (e.g. 'ok'), and an 'roi_proof' object showing the compression_ratio_pct achieved during repair/cleaning.

Example use cases

Fix scraped API response data

“I got this mangled JSON back from a web scrape and it has trailing commas and missing brackets — can you repair it so I can actually use it? Here's the broken string: {"items": [{"id": 1, "name": "Widget",}, {"id": 2}”

Recover LLM-generated JSON output

“My language model returned JSON with some syntax errors and I can't parse it downstream. Can you clean it up and return a valid JSON object? Here's what it output: {"result": "success" "count": 42 "data": [1, 2, 3}”

Sanitize user-submitted JSON payload

“A user submitted some JSON configuration through our form but it looks like it got corrupted with encoding issues and extra characters. Can you repair this JSON before I store it? Input: {"config": {"theme": "dark", "lang": "en",, "timeout": 30}”

Technical details

Endpoint

GEThttps://hn-pulse.agentdiet.dev/v1/json-repair?utm_source=zero.xyz

When to prefer

Choose this endpoint when you have a specific malformed or syntactically broken JSON string that needs to be automatically repaired into valid, parseable JSON. It is especially useful in agentic pipelines where LLMs or scrapers produce nearly-valid JSON with minor syntax errors (trailing commas, missing brackets, unclosed strings). It includes a compression ratio metric useful for auditing how much cleanup was done.

Side effects

Input JSON is too malformed to recover any structure — returns an error or empty data object
Missing required 'input' or 'method' fields returns a validation error
Non-JSON input types may not be handled correctly
Network timeout or service unavailability returns a 5xx error
HTTP 402 payment required if USDC micropayment is not sent
