--- title: "ISTAT consumer confidence" method: GET path: "/api/v1/istat/consumer-confidence" tags: ["Statistical Agencies"] --- # ISTAT consumer confidence `GET /api/v1/istat/consumer-confidence` ## Request - Base URL: `https://sugra.ai` - URL: `https://sugra.ai/api/v1/istat/consumer-confidence` - Auth: API key in header `x-api-key` - TypeScript: (a function with typed inputs; its response is checked against the schema) Italian National Institute of Statistics (ISTAT) consumer confidence for Italy and four areas, monthly, in index points: the consumer confidence climate (COF) and the economic, personal, current and future climates. Default: Italy, base 2021=100, not seasonally adjusted, which is the headline ISTAT publishes. The former base 2010=100 (not seasonally adjusted and seasonally adjusted) ended in December 2023 and is served from January 2021 to December 2023: choose it with base_year=2010. Bases and adjustments are separate series and are never mixed in one answer; a combination ISTAT does not publish (base 2021 seasonally adjusted) answers 404. A monthly survey: latest_period is the newest survey month of the series returned, and the data is refreshed from ISTAT once a day. Source: ISTAT (CC BY 4.0), processed by Sugra. ## Query parameters - `area` string, nullable: Territory: IT Italy, ITC North-West, ITD North-East, ITE Centre, ITFG South and Islands. Default IT. - `climate` string, nullable: Climate code: COF, COF_ECO, COF_PER, COF_COR, COF_FUT. Omit for all five. - `base_year` string, nullable: Index base year: 2021 (default, 2021=100) or 2010 (2010=100, served 2021-01 to 2023-12). - `adjustment` string, nullable: N (default, not seasonally adjusted) or Y (seasonally adjusted, base 2010 only). - `start_period` string, nullable: First month: 2024 or 2024-01. - `end_period` string, nullable: Last month: 2026 or 2026-09. ## Response `200` One series per climate in index points, with its label, territory and base. - EnvelopeIstatConfidenceData - `data` IstatConfidenceData, required - `topic` string, nullable: Consumer confidence. - `area` string, nullable: Territory code of this answer. - `area_name` string, nullable: Territory name. - `frequency` string, nullable: M. - `unit` string, nullable: Unit of every value in this answer: index points. - `base_year` integer, nullable: Base year of every series in this answer. - `base` string, nullable: The base as ISTAT states it, e.g. 2021=100. - `adjustment` string, nullable: N or Y for every series in this answer. - `adjustment_label` string, nullable: Not seasonally adjusted or Seasonally adjusted. - `latest_period` string, nullable: Newest month of the series in this answer (its own base and adjustment), whatever the window. - `count` integer, nullable: Observations across the series returned. - `series` IstatConfidenceSeries[], nullable: One series per climate. - `climate` string, nullable: Climate code. - `istat_code` string, nullable: ISTAT's series code, e.g. COF_21_WE. - `label` string, nullable: English label of the climate. - `group` string, nullable: headline or sub-climate. - `area` string, nullable: Territory code. - `area_name` string, nullable: Territory name. - `base_year` integer, nullable: Base year of the index. - `base` string, nullable: The base as ISTAT states it, e.g. 2021=100. - `adjustment` string, nullable: N or Y. - `adjustment_label` string, nullable: Not seasonally adjusted or Seasonally adjusted. - `unit` string, nullable: index points. - `frequency` string, nullable: M. - `first_period` string, nullable: First month of the full series. - `last_period` string, nullable: Last month of the full series. - `count` integer, nullable: Observations returned in the window. - `data` IstatConfidenceDatum[], nullable: Observations, oldest first. - `period` string, nullable: Survey month, YYYY-MM. - `value` union: Index points. - integer - number - `source` string, nullable: Credit: the Italian National Institute of Statistics (ISTAT). - `license` string, nullable: CC BY 4.0. - `attribution` string, nullable: Source: ISTAT (CC BY 4.0), processed by Sugra. - `modified_notice` string, nullable: States that the data was reshaped by Sugra. - `meta` SugraMeta, required: Metadata on a /api/v1/* response envelope built through `helpers.response.sugra_response`, which is how routes are expected to answer. A route that assembles its own `meta` dict carries only the keys it writes itself, so an optional field below can be absent because this response has nothing to report OR because that route does not build its envelope here - the two are not distinguishable from the outside. - `endpoint` string, required: Requested endpoint path. - `data_time` string, required: ISO 8601 timestamp the data on this response is stamped with. It is the source's own timestamp whenever the source supplied one this API could read; when it did not, this field falls back to the value of `response_time` and `data_age_days` is omitted, so the PRESENCE of that field is the signal to read - with the one exception named in its own description, a route that substitutes its own current time for a source timestamp it never received. Usually UTC (`Z`), but a source stating its own numeric offset keeps it (2026-04-16T14:30:00+09:00) rather than being converted a second time. For a source that publishes by period this is the period's START (see `period`) and for one that publishes by calendar day it is that day's midnight - in neither case a moment at which anything was observed or released. - `response_time` string, required: ISO 8601 UTC timestamp when this response was produced. - `provider` string, required: API name and version. - `data_age_days` number, nullable: Age of the data in days at the moment this response was produced, i.e. `response_time` minus `data_time`. Present ONLY when the timestamp this response is stamped with is a clock time that could be read as a real instant. It is ABSENT - never 0 - in every other case. Absent when no readable source timestamp was supplied, because `data_time` then repeats `response_time` and a zero age would assert that the data is current precisely where its true age is unknown. Absent when the source names a calendar day, a month, a quarter or a year (see `period`): the instant is then a boundary this API anchored at midnight, and time since a day or a quarter BEGAN is a different quantity from the age of the data - a daily series is out by up to a day, a quarterly one by up to a quarter. A midnight counts as such a boundary whichever zone it is stated in, and whether the source stated it or this API anchored it. The one case this field cannot see is a route that substitutes its own current time for a source timestamp it never received: the substituted value is a real, readable instant and is indistinguishable from one the source stated, so the age reads as roughly 0. The shared cache-and-fetch helper behind most routes stopped doing that, but the presence of this field is a statement about the timestamp the response carries, not a guarantee about the route that supplied it. Rounded to 0.001 day (86.4 seconds), so 0.0 is a real measured age anywhere within roughly +/-43 seconds and not a stand-in for unknown; a source stamping an instant in the future reports a negative value (-0.001 or less) rather than being clamped. Sources publish on very different cadences, so a non-zero age is normal, not an error. Preserve absence in client code: a generated client that materialises a missing optional number as its numeric default turns 'age unknown' back into 'age zero', which is the exact confusion this field exists to remove. - `source` string, nullable: Identifier of the primary upstream source used for this response. - `attribution` string, nullable: Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response. - `source_url` string, nullable: The publisher's own public page for the data this response answers, so a person or an agent can open the same data at the source. Present only on responses from the official publishers that have such a page for the exact data asked: FRED, SEC EDGAR, the European Central Bank, the U.S. Treasury, GLEIF and the World Bank. Absent where no such page exists (a search, a catalog or a multi-series batch) and on every other source. For the European Central Bank it is the page of the dataflow the series belong to. - `citation` string, nullable: A ready citation line that can be pasted as is: the publisher, the dataset or series title when the route has it with its identifier, the `source_url` page and the date this response was produced. Present exactly when `source_url` is. It does not replace `attribution`, which carries a notice a source requires and must be kept as sent. - `fallback_used` boolean, nullable: True when the primary source failed and a fallback produced the data. - `fallback_chain` string[], nullable: Ordered list of sources attempted, in the order they were tried. - `cached` boolean, nullable: True when this response was served from the internal cache. - `stale` boolean, nullable: True when the response is known stale under its source freshness policy, or when a cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data. - `stale_since` string, nullable: ISO 8601 UTC timestamp of the last good copy this response was served from. Present only when stale is true. - `period` string, nullable: Unit of observation, when the source publishes by period rather than by instant. `data_time` carries the period's START instant so it stays machine-readable; this field preserves what that instant used to mean, which the conversion would otherwise erase. Present only for such sources, and only when the source hands the API the label itself - a client that converts the period to its start instant before building the envelope loses the label, though not the age exclusion, which is decided by the instant. Note that `data_age_days` is omitted whenever this is present, because an age measured from a period start is not a freshness figure. - `notes` string, nullable: Data-quality caveat about THIS response - how old the underlying report is, a chokepoint AIS lower-bound, or that a source-reported `data_time` could not be read and the response time is shown instead. Distinct from `attribution`, which is a licensing obligation. Multiple caveats are joined with ' | '. Present only when there is one. ## Other responses - `401`: Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401. - `422`: Validation Error - `429`: Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window. - `500`: This API answered a shape its own schema refuses. Typed body `error: response_shape_invalid`. Stays a 500. Not an upstream failure. - `503`: Upstream source is temporarily unavailable. Retry after a short delay. `detail` is text, or the typed object with source and retry hint when the source is unreachable. ## Changes > 74 revisions in range; 1 not diffed. - **2026-11-10** `2867db71b7aa`: 2 info - response property `data/count` list-of-types was narrowed by removing types `number` from media type `application/json` of response `200` - response property `data/series/anyOf[subschema #1]/items/count` list-of-types was narrowed by removing types `number` from media type `application/json` of response `200` - **2026-11-10** `b243ad417d29`: 1 info - endpoint added [Operation history](https://skmtc.dev/sugra/apis/sugra-api/changes/api/v1/istat/consumer-confidence/get.md) --- [API](https://skmtc.dev/sugra/apis/sugra-api.md) - [All operations](https://skmtc.dev/sugra/apis/sugra-api/llms.txt) - [OpenAPI document](https://skmtc.dev/sugra/apis/sugra-api/revisions/2867db71b7aa?raw)
