Tax-Delinquency Sources

GET /api/v1/tax-delinquencies/sources

List the delinquent-tax / certificate-sale feed sources the platform tracks, one row per county + tax year. Each row records the source vendor (LienHub / RealAuction, RealTaxLien, TaxCertSale, WFBS, PacificBlue, …), the certificate-sale portal URL, the source kind, whether it requires a login, and the last check / last-success timestamps. This is how you see which counties have delinquency coverage and where the data came from.

Authentication

curl -H "X-API-Key: fpapi_test_..." \
  "https://api.floridapropertyapi.com/v1/tax-delinquencies/sources?county=polk&active=true"

There is also a per-county convenience route:

curl -H "X-API-Key: fpapi_test_..." \
  "https://api.floridapropertyapi.com/v1/tax-delinquencies/sources/polk"

// JavaScript (fetch)
const res = await fetch(
  "https://api.floridapropertyapi.com/v1/tax-delinquencies/sources?county=polk&active=true",
  { headers: { "X-API-Key": "fpapi_test_..." } },
);
const body = await res.json();
console.log(body.data);

# Python (requests)
import requests

res = requests.get(
    "https://api.floridapropertyapi.com/v1/tax-delinquencies/sources",
    params={"county": "polk", "active": "true"},
    headers={"X-API-Key": "fpapi_test_..."},
)
res.raise_for_status()
print(res.json()["data"])

Dataset freshness

GET /api/v1/tax-delinquencies/freshness returns a small object summarizing the delinquency dataset: total record count, latest tax year, last ingested timestamp, and last source-success timestamp. Use it to decide whether to re-pull.

Error Responses

Status	Code	Cause
401	unauthorized	Missing or invalid API key.
429	rate_limited	Rate limit exceeded.
500	internal_error	Server error — retry with backoff.

Data Coverage

This endpoint is the source of truth for which counties have delinquency coverage — tax-delinquency / certificate coverage is rolling out county by county, and each row records the vendor, source kind, and last-success timestamp. Counties without a row have no feed loaded yet.

Rate Limits

Every /api/v1/* response (including 429) carries X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset headers, plus the IETF RateLimit structured field. See Rate Limits for per-tier quotas and backoff guidance.
