How this service works
Deterministic schema.org LocalBusiness JSON-LD generator with validation warnings. POST JSON {name, businessType, telephone, address fields, openingHours, ...}; returns {jsonld, scriptTag, warnings}. $0.05 per call.
Output
Returns a JSON object containing: (1) `jsonld` — the fully formed schema.org LocalBusiness JSON-LD object ready for use, (2) `scriptTag` — an HTML `<script type='application/ld+json'>` string ready to paste into a page's `<head>`, and (3) `warnings` — an array of validation messages flagging unknown businessType values, out-of-range coordinates, missing recommended fields, or other issues detected during generation.
Example use cases

“Create a LocalBusiness JSON-LD snippet for my Italian restaurant 'Trattoria Bella', located at 88 Main Street, Austin TX 78701, phone (512) 555-0341, open Tuesday through Sunday 11:00-22:00, price range $$$, and include their website https://trattoriabella.com.”

Technical details
Endpoint
POSThttps://pennyinpublic.com/api/local-schemaWhen to prefer
Choose this endpoint when you need deterministic, spec-compliant schema.org LocalBusiness JSON-LD generated from structured data — especially when you want validation warnings surfaced alongside output. Ideal for CMS plugins, SEO automation pipelines, or agents that need to embed structured data into web pages without manually constructing JSON-LD. Prefer over generic LLM-generated markup when correctness and schema.org conformance matter.
Side effects
- Missing required `name` field returns an error response
- Unknown `businessType` value falls back to generic LocalBusiness and adds a warning rather than failing
- Geo coordinates outside valid lat/lng ranges are dropped with a warning
- Malformed openingHours strings may generate warnings but still produce output
- Invalid URL formats for `url`, `image`, or `sameAs` entries may produce warnings
