The daily counter resets at 9:30 AM Eastern Time. AAPL stock, AAPL options and the VFINX mutual fund consume no credits and answer without a token, while a keyless call for another symbol answers HTTP 401. The plan is reached through a 30-day trial that switches to Free Forever when it ends. The next plan up is Starter at USD 30 a month when paid monthly, with 10,000 daily credits. - per-object cap: unverified: no per-response row cap is stated on the pages read; each symbol in a multi-symbol response costs one credit | source: [2] - retention: 1 year of historical data on Free Forever; a request for older data is denied | source: [2] | note: A query API with no stored objects. - egress: not metered in bytes; the 100 credits a day bound what a free token can pull, with at most 50 simultaneous requests | metered: no | source: [2] - identity: email | detail: The sign-up starts with a choice of a 30-day Starter or Trader trial, both labelled no credit card required, and continues with an Account Info step and a Contact Info step. The account verification page lists name, address, email, phone number and employer details as the information collected for the identity check that paid subscribers complete, and free and trial account holders have not completed it. unverified: whether the Account Info and Contact Info steps of the free sign-up ask for a phone number or an address, behind a sign-up. The API token is emailed to the address used to sign in. - interface: rest - limits: - request-rate (binding): 100 API credits a day on Free Forever, reset at 9:30 AM Eastern Time [3] - per-ip-shaping: one IP address at a time per account; at most 50 simultaneous requests [2] - limits note: Plan gating: Free Forever reaches the standard pricing endpoints only; premium endpoints with reference data such as earnings are paid. Bulk path: multi-symbol responses cost one credit per symbol. - binding note: 100 credits a day is met first; a response that lists several symbols spends one credit per symbol. - interface detail: GET https://api.marketdata.app/v1/{endpoint} with a Bearer token in the Authorization header or in a URL parameter; the answer is HTTP 203 instead of 200 when it is served from the caching tier. A Google Sheets add-in reads the same data. - endpoint: https://api.marketdata.app/v1/stocks/quotes/AAPL/ - tooling: any HTTP client; official SDKs for JavaScript, TypeScript, Python and Go; a Google Sheets add-in - composes with: 100 credits a day of 24-hour-delayed prices with 1 year of history, and AAPL stock and options with no token for wiring tests; current quotes need a free real-time feed such as Finnhub or Twelve Data, or a paid plan here. - reliability: Past the daily credits the API answers HTTP 429 until the 9:30 AM Eastern Time reset; HTTP 203 is a cached success; free data is delayed 24 hours. - notes: Free Forever data is delayed 24 hours and covers the standard pricing endpoints; AAPL stock and options and the VFINX mutual fund answer with no token. - evidence note: The plan, credits, delay and history are read from the first-party pricing, plan-limits, rate-limiting and free-accounts pages, and the keyless AAPL path was measured (HTTP 203 with 0 credits consumed). A free token was not exercised, so the behaviour past 100 credits and the later sign-up steps are unverified: behind a sign-up. - evidence: - [1] 2026-11-02: the Free Forever plan is USD 0 forever | capture: sha256:6815ce6f55415e54c213b33a392bcbcf43a7d41e5a0943c467200931cc8d0ca0 | quote: Free Forever Best option for students or small side projects. $0 Forever - [1] 2026-11-02: the Free Forever plan lists 100 daily API credits | capture: sha256:6815ce6f55415e54c213b33a392bcbcf43a7d41e5a0943c467200931cc8d0ca0 | quote: - 100 Daily API Credits - [1] 2026-11-02: the Free Forever plan lists 24-hour delayed stock data | capture: sha256:6815ce6f55415e54c213b33a392bcbcf43a7d41e5a0943c467200931cc8d0ca0 | quote: - 24h Delayed Stock Data - [1] 2026-11-02: the Free Forever plan includes 100 Sheets formulas | capture: sha256:6815ce6f55415e54c213b33a392bcbcf43a7d41e5a0943c467200931cc8d0ca0 | quote: - 100 Sheets Formulas - [1] 2026-11-02: the next plan up, Starter, is USD 30 a month when paid monthly | capture: sha256:6815ce6f55415e54c213b33a392bcbcf43a7d41e5a0943c467200931cc8d0ca0 | quote: Annual commitment required. $30 when paid monthly. - [1] 2026-11-02: no credit card is needed to start the trial, which moves to Free Forever at its end | capture: sha256:6815ce6f55415e54c213b33a392bcbcf43a7d41e5a0943c467200931cc8d0ca0 | quote: No credit card is needed to start your trial, so you will never be billed unless you decide to upgrade to a paid plan during your trial. - [4] 2026-11-02: the Free Forever plan allows 100 API requests per day | capture: sha256:11be5edb1830a0cf03f20f6e0132d46d5f26bdc145e339af742ef26e274cfdea | quote: We offer the "Free Forever" plan, which allows for 100 API requests per day. - [4] 2026-11-02: free and trial plans reach back 1 year only | capture: sha256:11be5edb1830a0cf03f20f6e0132d46d5f26bdc145e339af742ef26e274cfdea | quote: Free and trial plans cannot access data older than 1 year. - [4] 2026-11-02: free accounts only receive data delayed by at least 24 hours | capture: sha256:11be5edb1830a0cf03f20f6e0132d46d5f26bdc145e339af742ef26e274cfdea | quote: Free Forever and trial accounts only have access to data that is delayed by at least 24 hours. - [2] 2026-11-02: daily credits are 100 on Free Forever and 10,000 on Starter | capture: sha256:78560bd5ad41b750a20e1be553f928ef3c348a549ed180e41717d61d1e517b2a | quote: | Daily Credits | 100 | 10,000 | 100,000 | No Limit | No Limit | - [2] 2026-11-02: a multi-symbol response costs one credit per symbol | capture: sha256:78560bd5ad41b750a20e1be553f928ef3c348a549ed180e41717d61d1e517b2a | quote: each symbol included in the response consumes credits - [2] 2026-11-02: an account connects from one IP address at a time | capture: sha256:78560bd5ad41b750a20e1be553f928ef3c348a549ed180e41717d61d1e517b2a | quote: Each account may only connect from one IP address at a time. - [2] 2026-11-02: every plan allows at most 50 simultaneous requests | capture: sha256:78560bd5ad41b750a20e1be553f928ef3c348a549ed180e41717d61d1e517b2a | quote: All plans are subject to a maximum of 50 simultaneous requests at any given time. - [2] 2026-11-02: Free Forever reaches pricing data only | capture: sha256:78560bd5ad41b750a20e1be553f928ef3c348a549ed180e41717d61d1e517b2a | quote: The Free Forever plan only provides access to pricing data. - [2] 2026-11-02: a request for data older than the plan allows is denied | capture: sha256:78560bd5ad41b750a20e1be553f928ef3c348a549ed180e41717d61d1e517b2a | quote: If you request data older than your plan allows, the request will be denied. - [3] 2026-11-02: the Free Forever plan is 100 credits per day | capture: sha256:51514694cff2fee874a3c61b2cf8576ee61427c92083690965a5e8115c333fad | quote: - Free Forever Plan: 100 credits per day. - [3] 2026-11-02: the daily counter resets at 9:30 AM Eastern Time | capture: sha256:51514694cff2fee874a3c61b2cf8576ee61427c92083690965a5e8115c333fad | quote: The usage counter for all plans with a daily limit resets at 9:30 AM Eastern Time (NYSE opening bell). - [3] 2026-11-02: requests past the credits answer HTTP 429 until the window resets | capture: sha256:51514694cff2fee874a3c61b2cf8576ee61427c92083690965a5e8115c333fad | quote: further requests will return `429` responses until the credit window resets. - [3] 2026-11-02: AAPL stock, AAPL options and the VFINX mutual fund consume no credits | capture: sha256:51514694cff2fee874a3c61b2cf8576ee61427c92083690965a5e8115c333fad | quote: Certain free trial symbols like AAPL stock, AAPL options, and the VFINX mutual fund do not consume credits. - [5] 2026-11-02: the AAPL ticker works with no authentication and no account | capture: sha256:66011207c5cf8e4867f88d111b1340a02a64f4c0c71b109fec6da349b7ae71c4 | quote: Our API can be used with the AAPL ticker with no authentication needed.
