The series accrues forward from when archiving began, so it is sparse until enough days accumulate. Pass `bedrooms` to scope to one unit size, or omit it to get every bedroom bucket per day. **Tier:** Free+ ## OpenAPI ````yaml GET /market/rentals/history openapi: 3.1.0 info: title: Borough API description: > NYC Real Estate Data API: structured access to rental and sale listings, building details, neighborhood data, and market statistics. ## Authentication All authenticated endpoints require a `Bearer` token in the `Authorization` header: ``` Authorization: Bearer BOROUGH- ``` License keys are provisioned automatically when you subscribe via [Polar.sh](https://polar.sh/qwady-solutions-llc/portal). Free-tier endpoints (search, areas, market, and photos) work without authentication but are tracked per IP and subject to IP-based rate limits of 10 requests per minute. The health check endpoint remains fully public. ## Rate Limits | Tier | Requests/min | Requests/month | Max perPage | |----------|-------------|----------------|-------------| | Free | 10 | 100 | 10 | | Starter | 30 | 5,000 | 50 | | Pro | 60 | 25,000 | 500 | | Business | 120 | 100,000 | 500 | Tiered API responses include the `X-RateLimit-Limit` and `X-Quota-*` headers, plus an `X-Request-Id` header (UUID v4) for request tracing and debugging. Note that 429 responses additionally carry a `Retry-After` header and an `error.retryAfter` value in the body. The health check remains fully public and does not carry quota headers. ## Data Freshness Freshness-aware JSON data responses include a `meta.dataAge` field (ISO 8601) indicating when the underlying data was last scraped, and a `meta.source` field indicating how the data was served (`cached`, `stale`, or `live`). Public cache cadence varies by dataset: rental search refreshes every 6h, sale search every 8h, listing detail sweeps every 12h, buildings every 3 days, broadband enrichment monthly, and market snapshots daily at 05:00 UTC. Paid tiers use freshness thresholds to trigger background refreshes when cached data exceeds the threshold for that route family. | Tier | Search Threshold | Listing Threshold | Building Threshold | |----------|------------------|-------------------|--------------------| | Starter | 8h | 30min | 6h | | Pro | 8h | 15min | 3h | | Business | 8h | 10min | 2h | ## Photo URLs Listing and building responses include photo keys (32-character hex hashes).
