ECB Daily Reference Rate Evidence API

Export a short official daily ECB reference-rate window for one supported quote currency and EUR denominator. One SDMX EXR.D.CURRENCY.EUR.SP00.A CSV request, inclusive1..31 calendar days since1999, first1..31 observations. Retain exact decimal source text and date, currency, denominator, status and unit declarations. Verify returned series identity and zero unit multiplier; no inversion, scaling, conversion or rounding. Missing business days are absent rows, not zero rates or forward-filled values.

Reference rates are informational; the ECB discourages using them for transaction purposes. They are not executable/live exchange quotes, trading signals, investment advice, exchange execution, guaranteed future values or arbitrage. No financial account or transfer. CSV schema, duplicate columns/dates, out-of-window rows and nonfinite/nonpositive decimals are checked; malformed data is a source error. Cap truncation is explicit. A provider404 is an error, not an empty successful rate series. Source units are retained and rates can be revised; hashes detect selected-field changes only. Attribute the European Central Bank.

Quick start

{"currency": "USD", "startDate": "2025-01-06", "endDate": "2025-01-07"}

Pricing and budget

0.0005 USD per emitted daily reference observation (0.5 USD per1000), plus0.005 USD startup at default256MB. Higher memory can multiply startup events; check effective Store pricing. Failed/empty sources do not emit result charges; startup can still apply. At zero result budget, input validation occurs but no upstream request is sent, and rowsAvailable is null (unknown). A positive budget can request the bounded source set before output; emission stops at the result cap and complete=false/PARTIAL_BUDGET reports truncation.

Snapshot, integration and limits

Use dataset rows together with OUTPUT and SNAPSHOT. Pass SNAPSHOT.previousHashes as previousHashes in a later run. NO_BASELINE/FIRST_SEEN/UNCHANGED/CHANGED compare only selected metadata including itemKey and sourceUrl; missing records are not deletions. FIRST_SEEN means absent from the supplied baseline. There is no persistent hidden state or automatic polling. Export JSON/CSV/Excel through the default dataset.

API example: POST https://api.apify.com/v2/actors/soilair~ecb-daily-reference-rate-evidence-api/runs with your Apify Authorization header and the JSON input above. Poll the returned run; read dataset items and OUTPUT/SNAPSHOT records using its store IDs. Do not place tokens or confidential data in input. No upstream key is needed. Results live in Apify run storage according to retention; no separate analytics service.

Only fixed HTTPS provider endpoints are constructed from validated identifiers. Public-IP DNS validation, pinned connections, TLS hostname verification,2MiB decoded responses, approximately95 seconds of network budget, at most5 same-provider redirects. Official API calls are distinct from website crawling; no arbitrary URLs or HTML pages. No linked documents/files are fetched. Queries are sequential with1-second spacing. Provider403/429 or Retry-After stops later calls; retry instructions are reported and no retry/proxy/circumvention is attempted. Shared IP limits and changes to upstream services can still block runs. Caller must respect provider headers and cache/reduce repeated requests. Text is data and should not be executed.

Developed with AI assistance. Tests and live/cloud comparisons qualify the selected-field contract; they do not prove commercial demand, provider uptime or a legal/license determination. Support: share a run ID and expected fields, without credentials or private material.
