## Marketstack (APILayer)

- `data-apis/marketstack` | fails-quota | evidence documented | binding request-rate | category market data API (end-of-day stock prices, tickers, exchanges) | tier Free
- needs card no, phone no, ID no, institution no | verified 2026-11-03T00:28:53.394Z (live) | stale on 2026-12-04
- url https://marketstack.com/pricing
- free tier: Free plan USD 0/month, free forever: 100 requests per month, end-of-day data, 1 year of history, no support | unit: requests | metered on: request-count | read on: 2026-10-31 | source: [1] | note: Each symbol in a request consumes one request, up to 100 symbols per call, and a page holds up to 1000 rows. The APILayer product page shows the free plan as 100 Total Requests while its FAQ on the same page says 100 per month; the marketstack.com pricing page and FAQ say per month. The cheapest paid plan is Basic at USD 8.99/month billed yearly with 10,000 requests per month. US end-of-day prices are licensed from Tiingo.
- per-object cap: 1000 rows per page and 100 symbols per call; 1 year of history on the free plan | source: [2]
- retention: not applicable
- egress: not metered in bytes; the 100 requests a month bound what a free key can pull | metered: no | source: [1]
- identity: email | detail: The free signup form asks for a first name, last name, email and password, and under Billing Details an address, postal code, country and city (state optional); no card field was seen on the free form. Card payment is named for paid plans.
- interface: rest
- limits:
  - request-rate (binding): 100 requests per month on the free plan; each symbol in a request counts as one [1]
  - request-rate (binding): 5 requests per second [3]
  - per-object-cap: 1000 rows per page, 100 symbols per call [2]
- limits note: History window: 1 year on the free plan, 10 years on Basic, 15+ years above; no limits[] kind names a history window. Bulk path: no bulk path.
- binding note: 100 a month, with each symbol counted, is spent long before the 5 per second rate or the row caps matter.
- interface detail: GET https://api.marketstack.com/v2/eod?access_key=...&symbols=AAPL over HTTPS on every plan; v1 paths remain. A call with no access_key answered HTTP 401 missing_access_key.
- endpoint: part of interface detail
- tooling: curl or any HTTP client
- composes with: Its US end-of-day prices are licensed from Tiingo, whose free plan allows 1000 requests a day against 100 a month here, so Tiingo is the larger free route to the same prices.
- reliability: Past the monthly volume the API answers HTTP 429 too_many_requests, and past 5 requests per second it answers 429 rate_limit_reached; API errors are not counted toward the monthly quota; an error answer is a JSON object with an error member holding a code and a message.
- notes: A working free key, but 100 requests a month with each symbol counted and 1 year of end-of-day history is too small for a data workload; the same US prices come from Tiingo, whose free plan is 1000 requests a day with 30+ years of history.
- evidence note: The free quota, history and signup fields are documented on the pricing, FAQ and signup pages; the 5 per second rate is stated on the current Getting Started page of the APILayer documentation. A probe measured that a call with no key answers HTTP 401. The monthly cut-off answer, its body and its reset moment need a free key to measure (unverified: behind a sign-up).
- extras:
  - bulk_path: no bulk path
  - history_depth: 1 year on the free plan; 10 years on Basic; 15+ years on Professional and Business
  - quota_wording_conflict: apilayer.com/products/marketstack shows 100 Total Requests on the plan card and 100 per month in its FAQ
  - cutoff_wording_conflict: marketstack.com/contact says the system allows a maximum overdraft of 5% beyond the quota limit and disables API access at 120% unless overage billing is enabled; marketstack.com/faq says overage fees apply after 100% of the allowance; which applies to a Free key, which lists no overage, is unverified: behind a sign-up
