Input: dataset path (acs/acs5, acs/acs1, acs/acs5/subject, acs/acs5/profile, dec/pl, dec/dhc, pep/population, cbp ...), vintage, 1-200 variable names or group(TABLE) tokens, and a geography as Data API for/in predicates (for: 'county:*', in: ['state:06']). Returns one row per geography with values as published, sentinels turned into null plus annotation, FIPS parts, variable metadata with units, and the equivalent api.census.gov URL. Unknown variables are rejected with invalid_input naming them. - [Datasets](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/datasets): Search the Census Data API catalog. Input: free-text query over dataset path, title and description plus an optional vintage (year). Returns one record per dataset/vintage with its API endpoint, metadata links, publication date and supported geography levels. - [Geographies](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/geographies): Geography resolver. Input: a place, county, state, tract or other geography name (e.g. 'Travis County, Texas'). Returns matching Census geographies with summary level, GEO_ID, FIPS parts and the exact `for`/`in` predicates to pass to `data`. - [Popest get](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/popest_get): One PEP geography by its own codes, as its estimate-year records (same shape as popest_list). counties: state + county (county omitted or 000 = the state row). subcounty: the per-state file; select by place (default SUMLEV 162, or 157 together with county), cousub + county (SUMLEV 061), concit, or an explicit sumlev; nothing but state = the state row. More than one matching row is invalid_input asking for sumlev; none is not_found. - [Popest list](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/popest_list): List Vintage 2020-YYYY population estimates from one PEP file as one record per geography and estimate year: counties (SUMLEV 040 states and 050 counties; components of change, group quarters and per-1,000 rates) or subcounty (places, county subdivisions, consolidated cities; population only). The whole file is fetched per call (2.1 MB counties, 7.5 MB national subcounty, ~30 KB per state) and paged from memory; the cursor pins vintage, file, Last-Modified and size and a changed file fails with publication_changed. source_record_id = v::::. Names are decoded from Latin-1. - [Popest status](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/popest_status): Cheap version check of the Population Estimates Program (PEP) file tree on www2.census.gov: newest 2020-YYYY vintage directory, then HEAD of counties/totals/co-est-alldata.csv and cities/totals/sub-est.csv (size, Last-Modified, publication_id = v::), plus the per-state sub-county files from the cities/totals listing. No publisher hash exists; popest_list reports the SHA-256 of the file it reads. - [Saipe get](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/saipe_get): One SAIPE record by state and county FIPS for a year: reads est-.txt (county omitted or 000 = the state row) or, for state 00 / US, the national row of estus.txt. Same record shape as saipe_list. - [Saipe list](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/saipe_list): List SAIPE state-and-county poverty and median household income estimates for one year: estall.txt (US, 51 states, every county; 3,196 lines for 2024) or, with state, est-.txt (state row first, then its counties). Fixed-width positions per the layout README: state 1-2, county 4-6, poverty all ages 8-48, age 0-17 50-90, related children 5-17 92-132, median household income 134-153, under 5 155-192 (US and states only), name 194-238, postal 240-241, file tag 243-264. Blanks and '.' become null; FIPS stay zero-padded strings. The file is fetched per call and paged from memory; the cursor pins year, file, Last-Modified and size. source_record_id = saipe:. - [Saipe status](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/saipe_status): Cheap version check of the Small Area Income and Poverty Estimates (SAIPE) state-and-county files on www2.census.gov: newest year directory, the file listing (estall.txt, estus.txt, est-.txt and the .xls twins), and for the national files estall.txt and estus.txt the exact size, Last-Modified, SHA-256 and line count (they are fetched: the server sends them gzip-encoded without Content-Length). publication_id = saipe::. - [Variables](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/variables): List variables of one dataset vintage. Input: dataset path and vintage, plus a group (table id such as B01003 or DP05) and/or a free-text query matched against group descriptions and variable labels. Returns variable name, verbatim label, concept, predicate type, group and the unit phrase the label carries. ## 1. Choose this provider when Discover Census datasets, variables and geography codes, then retrieve published estimates, margins of error and counts with source annotations; collect the Population Estimates Program county and sub-county files (Vintage 2020-YYYY) and the SAIPE state-and-county poverty and income files from www2.census.gov. ## 2.

estimates from one PEP file as one record per geography and estimate year: counties (SUMLEV 040 states and 050 counties; components of change, group quarters and per-1,000 rates) or subcounty (places, county subdivisions, consolidated cities; population only). The whole file is fetched per call (2.1 MB counties, 7.5 MB national subcounty, ~30 KB per state) and paged from memory; the cursor pins vintage, file, Last-Modified and size and a changed file fails with publication_changed. source_record_id = v::::. Names are decoded from Latin-1. - Instructions: Full collection of county or sub-county population estimates (annual population, births, deaths, migration) for a vintage, optionally for one state. - Cost: 5 credits per call - Capability file: [Popest list](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/popest_list) Accepted options: - `continuation` (string): Opaque cursor from the previous page's next_cursor. It pins the vintage, file, Last-Modified and size; when the source has moved on the call fails with invalid_input at /continuation (issue code publication_changed) instead of mixing versions. Example: `` - `file` (string, required): counties: counties/totals/co-est-alldata.csv (states and counties). subcounty: cities/totals/sub-est.csv (national, ~7.5 MB) or, with state, sub-est_.csv. Example: `counties` - `page_size` (number): Records (geography-years) per page; default 500. Example: `10` - `state` (string): Optional 2-digit state FIPS. counties: keeps that state's rows (state row included). subcounty: reads the per-state file sub-est_.csv instead of the national file. Pattern: ^[0-9]{2}$. Example: `` - `sumlev` (string): Optional summary level filter (050 counties only, 162 incorporated places, 061 county subdivisions ...). Pattern: ^[0-9]{3}$. Example: `` - `vintage` (number): Vintage year YYYY of the 2020-YYYY directory. Default: the newest directory listed under popest/datasets/. Example: `2021` Response schema example: ```json { "content_hash": "4f5a499d851e2cb48fd7a5405e5a9235453a8a66933657aacd10df0e264f35d5", "count": 6, "file": "counties", "file_name":

Input: dataset path and vintage, plus a group (table id such as B01003 or DP05) and/or a free-text query matched against group descriptions and variable labels. Returns variable name, verbatim label, concept, predicate type, group and the unit phrase the label carries. - Instructions: List variables of one dataset vintage. Input: dataset path and vintage, plus a group (table id such as B01003 or DP05) and/or a free-text query matched against group descriptions and variable labels. Returns variable name, verbatim label, concept, predicate type, group and the unit phrase the label carries. - Cost: 5 credits per call - Capability file: [Variables](https://alexandria.firecrawl.dev/agents/providers/census-gov/census/variables) Accepted options: - `cursor` (string): cursor Example: `` - `dataset` (string, required): Data API dataset path, e.g. acs/acs5, acs/acs5/profile, dec/pl, cbp. Pattern: ^[A-Za-z0-9_/]+$. Example: `` - `group` (string): Table id, e.g. B01003, S0101, DP05, P1. Pattern: ^[A-Za-z0-9_]{1,40}$. Example: `` - `page_size` (number): page_size Example: `20` - `query` (string): Tokens matched against group name/description (when no group is given; the first 5 matching groups are listed) or variable name/label/concept (within a group). Datasets with at most 5 tables (cbp, pep/population) whose descriptions do not match are searched by variable label instead. Example: `` - `vintage` (number, required): vintage Example: `2000` Response schema example: ```json { "complete": true, "count": 1, "dataset": "acs/acs5", "group": "B01003", "next_cursor": null, "observed_at_ms": 1789084800000, "records": [ { "attributes": [], "concept": "Total Population", "dataset": "acs/acs5", "group": "B01003", "label": "Estimate!!Total", "limit": 0, "name": "B01003_001E", "predicate_only": true, "predicate_type": "int", "scale": null, "source_url": "https://api.census.gov/data/2023/acs/acs5/groups/B01003.json", "unit": null, "vintage": 2023 } ], "retrieved_at": "2026-09-11T00:00:00Z", "schema_version": "1.0.0", "source_updated_at": null, "source_url": "https://api.census.gov/data/2023/acs/acs5/groups/B01003.json", "total": 6, "vintage": 2023, "warnings": [] } ```
