概览

GovRates API — US Per Diem + Fair Market Rent, joined by ZIP

Look up two essential US federal datasets for any ZIP code in a single call:

  • GSA per-diem: the official federal travel rates — maximum lodging plus M&IE (meals & incidental expenses), seasonal-aware. These are the inputs to a travel tax-free stipend calculation.
  • HUD Fair Market Rent (FMR) and Small Area FMR (SAFMR): rent by bedroom size (0–4 BR), including HUD's 90%–110% voucher payment-standard band used for Section 8 / Housing Choice Vouchers.

The free official sources exist, but they are two separate, clunky, separately-keyed government feeds with no ZIP-to-county join and no per-diem/FMR unification. GovRates returns both, joined and ZIP-resolved, as one clean JSON response — the answer a developer wants instead of wiring two .gov sources, and the answer a generic chatbot hallucinates.

Who it's for

  • Travel-nurse and healthcare-staffing pay and housing-stipend calculators
  • Corporate relocation / HR / business-travel tools
  • Real estate / property management / Section 8 voucher tools

Endpoint

GET /v1/lookup?zip=NNNNN — Returns the GSA per-diem AND the HUD Fair Market Rent for a ZIP code, joined in one response. Optional &month=1–12 resolves the seasonal lodging rate.

Example

Request: GET /v1/lookup?zip=10001

{
  "zip": "10001",
  "location": { "state": "NY", "county": "New York County", "areaName": "New York, NY HUD Metro FMR Area" },

  "perDiem": { "fiscalYear": 2026, "basis": "gsa-county", "area": "New York City", "mie": 92, "lodging": { "seasonal": true, "min": 179, "max": 342 } },
  "disclaimer": "Unofficial. Not affiliated with or endorsed by GSA or HUD."
}

Coverage & accuracy

  • FY2026 data. About 38,600 ZIP codes, all 50 states plus DC.
  • Every per-diem result is honestly flagged: basis "gsa-county" (a specifically-listed area), "standard" (the federal Standard CONUS rate, GSA's own default for unlisted counties), or "oconus" (Alaska, Hawaii, and US territories — set by DoD/State Dept and NOT returned as a fabricated CONUS rate).
  • Clean, consistent JSON; permissive CORS; fast edge responses.

GovRates Per Diem and Fair Market Rent API FAQs

不 政府费率是不官方的 也不与 GSA 或 HUD 有关联或被认可 它是基于公共领域的美国联邦数据构建的 包括 GSA 的 2026 财年日常津贴主费率和 HUD 的 2026 财年公平市场租金 / 小地区 FMR 通过邮政编码归一化并联接 每个响应中包含来源归属

GSA按县设置每日报销标准 basis="gsa-county"表示该邮政编码的县是一个具体列出的GSA区域,并有其自己的费率 basis="standard"表示该县没有单独列出,因此适用联邦标准CONUS费率(GSA自己的默认值) basis="oconus"表示阿拉斯加 夏威夷或美国领土,这些由国防部/国务院设定,并不包含在GSA CONUS数据集中(因此没有返回CONUS费率)

它们是HUD的90%和110%的小区域公平市场租金——地方公共住房管理局(PHA)设定实际第8部分/住房选择券支付标准的范围。GovRates返回FMR加上这个90-110%的范围;地方PHA在其中设定确切的标准

The data reflects the current U.S. federal fiscal year (FY2026). GSA per-diem rates and HUD Fair Market Rents are published annually (around October 1), and the API is refreshed each fiscal year so responses stay accurate. Every response includes the fiscalYear so you always know which year you are reading.

Common uses include travel-nurse and healthcare-staffing pay and housing-stipend calculators, corporate relocation and HR cost tools, business-travel expense apps, and real-estate or Section 8 voucher tools. A single ZIP lookup returns both the GSA per-diem (the inputs to a tax-free stipend) and the HUD Fair Market Rent (housing) for that location, so you do not have to wire up two separate government data sources.

The GovRates API returns two main types of data: GSA per-diem rates (including lodging and M&IE) and HUD Fair Market Rent (FMR) data, both for a specified ZIP code. This data is combined in a single JSON response for ease of use.

Key fields in the response include "zip," "location" (with state, county, and area name), "fairMarketRent" (with FMR by bedroom size), and "perDiem" (with lodging and M&IE details). Each field provides essential information for travel and housing calculations.

The response data is structured in a clean JSON format, with separate sections for location, fair market rent, and per diem. Each section contains relevant subfields, making it easy to parse and utilize for applications.

The primary parameter is "zip," which specifies the ZIP code for the lookup. An optional "month" parameter (1-12) can be included to retrieve seasonal lodging rates, allowing users to customize their requests based on specific needs.

The endpoint provides information on GSA per-diem rates (maximum lodging and M&IE) and HUD Fair Market Rent data (by bedroom size) for any ZIP code. This comprehensive data supports various applications in travel, housing, and real estate.

The data is sourced from public-domain U.S. federal datasets: the GSA's FY2026 Per Diem Master Rates and HUD's FY2026 Fair Market Rents. The API normalizes and joins these datasets for easier access and use.

Data accuracy is maintained by using official federal datasets that are updated annually. The API ensures that the data reflects the current fiscal year and includes a disclaimer indicating its unofficial status, promoting transparency.

Typical use cases include calculating travel stipends for healthcare staff, assisting corporate relocation and HR departments, and providing real estate professionals with accurate rental data for Section 8 housing. The combined data streamlines these processes.

定价页面上显示的本地货币基于您 IP 地址的国家/地区,仅供参考。实际价格以 USD(美元)为单位。当您付款时,即使您在我们的网站上看到以本地货币显示的等值金额,您的卡片对账单上也会以美元显示费用。这意味着您不能直接使用本地货币付款。
有时,银行可能会因其欺诈保护设置而拒绝收费。我们建议您首先联系您的银行,检查他们是否阻止了我们的收费。此外,您可以访问账单门户并更改关联的卡片以进行付款。如果这些方法不起作用并且您需要进一步帮助,请通过 [email protected]
价格由月度或年度订阅决定,具体取决于所选计划。
API 调用根据成功请求从您的计划中扣除。每个计划都包含您每月可以进行的特定数量的调用。只有成功的调用(由状态 200 响应指示)才会计入您的总数。这确保失败或不完整的请求不会影响您的月度配额。
Zyla API Hub 采用月度订阅系统。您的计费周期将从您购买付费计划的那一天开始,并在下个月的同一日期续订。因此,如果您想避免未来的费用,请提前取消订阅。

要检查您本月剩余多少 API 调用,请参考响应标头中的 "X-Zyla-API-Calls-Monthly-Remaining" 字段。例如,如果您的计划允许每月 1,000 个请求,而您已使用 100 个,则响应标头中的此字段将显示 900 个剩余调用。
要查看您的计划允许的最大 API 请求数,请检查 "X-Zyla-RateLimit-Limit" 响应标头。例如,如果您的计划包括每月 1,000 个请求,此标头将显示 1,000。
"X-Zyla-RateLimit-Reset" 标头显示您的速率限制重置之前的秒数。这告诉您何时您的请求计数将重新开始。例如,如果它显示 3,600,则意味着还有 3,600 秒直到限制重置。
是的,您可以随时通过访问您的账户并在账单页面上选择取消选项来取消您的计划。请注意,升级、降级和取消会立即生效。此外,取消后,您将不再有权访问该服务,即使您的配额中还有剩余调用。
