Get metadata for an economic data series by its identifier

How to use it

Fetch the metadata for a single economic data series by its identifier (e.g. GNPCA for real gross national product, UNRATE for the unemployment rate, GDP for gross domestic product). Returns the series title, units, observation frequency, seasonal-adjustment status, descriptive notes, the date range its observations cover, and when it was last updated. Use the observations endpoint to fetch the actual time-series values.

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• series_id string required — Series identifier (examples: "GNPCA", "UNRATE", "GDP")

Response

• @type string (default: "FredSeries")
• id string required
• frequency string nullable
• frequency_short string nullable
• seasonal_adjustment string nullable
• seasonal_adjustment_short string nullable
• units string nullable
• units_short string nullable
• notes string nullable
• observation_start_date string nullable
• observation_end_date string nullable
• last_updated_at string nullable

Errors

• 422 — The request body did not validate Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — Series not found Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
