Yes. The Free tier on Parse includes 100 API calls per month at no cost with a 5 request-per-minute rate limit. Paid tiers add more credits and higher rate limits: Hobby ($30/month, 1,000 credits, 20 req/min) and Developer ($100/month, 5,000 credits, 250 req/min).

What are the rate limits?

Rate limits are per Parse account, not per API: 5 requests/minute on Free, 20 on Hobby, and 250 on Developer. Exceeding the limit returns a 429 status code. The same limit applies regardless of which marketplace API you call.

How do I authenticate?

Send your Parse API key in the X-API-Key header on every request. Get a key by signing up at parse.bot — no credit card required for the free tier.

About the sc-charleston.publicaccessnow.com API

The Charleston County Public Access API exposes property assessment data from the Aumentum public access portal through a single lookup_property_by_pin endpoint that returns 11 structured fields per parcel. Given a 10-digit PIN, it returns the current owner name, land and market values, building characteristics, active exemptions, and acreage — all drawn from Charleston County, SC public records.

What the API Returns

The lookup_property_by_pin endpoint accepts a single required parameter — pin, a 10-digit parcel ID number with no dashes or spaces (e.g., 4611303102) — and returns a structured record for that parcel. Response fields include owner_name, city, zip, acreage, year_built, and tax_year, giving you the core identity and physical attributes of a property in one call.

Valuation and Assessment Data

Financial fields in the response cover land_value, building_value, market_value, and assessed_val, all expressed in whole-dollar integers. These values correspond to the tax year returned in tax_year. The exemptions field returns an array of strings listing any active exemptions on the parcel (e.g., homestead, agricultural), which affects the effective taxable value.

Data Source and Coverage

All data originates from the Charleston County, SC Aumentum public access portal, which serves as the county's official property tax assessment system. Coverage is limited to parcels within Charleston County. The PIN format matches the county's parcel numbering scheme, so you'll need a valid county-issued PIN to retrieve a record.

Common use cases

Verify current owner name and mailing address for a Charleston County parcel before a real estate transaction
Compare market_value and assessed_val across multiple parcels to identify assessment discrepancies
Filter properties by year_built to research the age distribution of structures in a target neighborhood
Audit active exemptions on a parcel to understand its effective tax burden
Pull acreage and land_value data to support land valuation or subdivision analysis
Track tax_year field to confirm data freshness when monitoring assessed values over time
Populate property detail pages in a real estate application with county-sourced assessment data

Frequently asked questions

Does sc-charleston.publicaccessnow.com have an official developer API?+

No. The Aumentum public access portal at sc-charleston.publicaccessnow.com does not publish a documented developer API or offer API keys to the public. This Parse API provides structured programmatic access to that data.

What does `lookup_property_by_pin` return for the valuation fields?+

It returns four integer fields: land_value (market value of the land), building_value (value of any structures), market_value (total combined market value), and assessed_val (the county's assessed value used for tax calculation). All values are in US dollars and correspond to the tax_year in the same response. Any of these may be null if the county record lacks that figure.

Does the API cover properties outside Charleston County, SC?+

No. The endpoint retrieves records only from the Charleston County, SC Aumentum portal. Other South Carolina counties use separate portals or different systems entirely. You can fork this API on Parse and revise it to point at another county's public access portal if you need broader coverage.

Does the API return sales history for a parcel?+

Sales history is noted in the endpoint description as data the source exposes, but it is not currently surfaced as discrete fields in the structured response — the current response shape covers owner info, values, and property characteristics. You can fork this API on Parse and revise it to extract and return individual sales transaction records.

What happens if the PIN I supply doesn't match a county record?+

The PIN must be a valid 10-digit Charleston County parcel ID with no dashes or spaces. If the PIN is malformed or does not correspond to a parcel in the county system, the endpoint will return null values or an empty result rather than property data. You can verify a PIN through the Charleston County Assessor's office before querying.
