- needs card no, phone no, ID no, institution no | verified 2026-11-02T00:23:51.279Z (live) | stale on 2026-12-03
- url https://www.exchangerate-api.com/
- disagrees on identity_kind: `data-apis/exchangerate-api` says email, `data-apis/exchangerate-api-open` says anonymous
- free tier: Free plan, USD 0, no card: 1.5K API requests a month with an API key, rates updated once every 24 hours. | unit: requests | metered on: request-count | read on: 2026-11-02 | source: [1] | note: The quota is soft-capped at 100 percent, with a little extra room. The Free plan has the standard and pair-conversion endpoints and base currency switching; historical data is for paid accounts only. The Pro plan is USD 10 a month for 30k requests, hourly updates and history from 1990. A separate keyless Open API has its own record (data-apis/exchangerate-api-open).
- per-object cap: not stated | source: [1]
- retention: not applicable
- egress: not metered in bytes; the 1.5K requests a month bound what a free key can pull | metered: no | source: [1]
- identity: email | detail: The sign-up form asks for an email and a password, and the key is active after email confirmation; no card for the Free plan.
- interface: rest
- limits:
  - volume-quota (binding): 1.5K API requests a month on the Free plan, soft-capped at 100 percent [1]
  - retention-clamped: no historical data on a free account; the history endpoint is for paid accounts [2]
- limits note: Rate per minute: not stated for the keyed plan on the pages read. Bulk path: none on the free plan.
- binding note: 1.5K requests a month binds first; the rates change once a day, so about 30 requests a month cover a full daily refresh.
- interface detail: GET https://v6.exchangerate-api.com/v6/YOUR-API-KEY/latest/USD (standard) and a pair-conversion request; JSON
- endpoint: https://v6.exchangerate-api.com/v6/latest
- tooling: curl or any HTTP client
- composes with: Daily rates for all currencies: one call a day uses about 30 of the 1.5K requests a month. The keyless Open API in data-apis/exchangerate-api-open needs no key at all.
- reliability: The vendor states that any aspect of a free plan, the quota included, may change or end at any time without notice.
- notes: Free requests: 1.5K a month. Rate limit: no per-minute rate stated; a soft cap at 100 percent of the quota. re-distribution is not allowed. Bulk path: none on the free plan; the keyless Open API is a separate lane.
- evidence note: Quota, update rate, history gate, caching and sign-up fields are quoted from first-party home, docs, terms and sign-up pages. No key was created.
- extras:
  - bulk_path: none on the free plan; history is paid
  - free_requests: 1.5K a month
  - history_depth: none on free; from 1990 on paid plans

- free tier: Open access API with no key: GET https://open.er-api.com/v6/latest/USD, rates updated once per day, rate limited per IP address. | unit: unlimited | metered on: none | read on: 2026-11-02 | source: [1] | note: The page names no request count and no per-minute number. Requesting once every 24 hours needs no further reading, and one request an hour per server never meets the limit. A rate limited IP address receives HTTP 429 for 20 minutes.
- per-object cap: not stated | source: [1]
- retention: not applicable
- egress: not metered in bytes; the per-IP rate limit bounds what a caller can pull | metered: no | source: [1]

- limits:
  - per-ip-shaping (binding): a rate limit per IP address with no published number; a limited address receives HTTP 429 for 20 minutes [1]
- limits note: Update rate: once per day. Bulk path: none; the page asks to cache the daily table.
- binding note: The only limit is the per-IP shaping with no published threshold; one request an hour never meets it.

- endpoint: part of the free tier
- tooling: curl or any HTTP client
- composes with: A daily table of all currencies with no sign-up; cache it for 24 hours. Pair this with data-apis/exchangerate-api when a key is acceptable.
- reliability: A rate limited IP address receives HTTP 429 and is let through again after 20 minutes.
- notes: Free requests: no count, no key. Rate limit: per IP address, no number published. re-distribution is not allowed. Bulk path: none.
- evidence note: Limits and license are quoted from the open access docs page. One keyless GET answered HTTP 200 with a success body; the rate threshold was not measured.
- extras:
  - bulk_path: none; one daily table of all currencies per request
  - free_requests: no count; per-IP rate limit, number not published
