Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Schema & documentation Benzinga +32

Benzinga 71

The docs are generated from 11 OpenAPI 3 specs in the public Benzinga/benzinga-docs repository, 80 operations, and the raw YAML is linked from the welcome page (25). llms.txt and a Markdown twin of every page (10). Operations carry a summary and a sentence or two on scope, with little on when not to use a call (12 of 20). Typed query parameters with enums on the calendar (50) and news (9) specs, and the token as a query parameter (10 of 15). Examples on most operations, but the error responses in the specs are thin, 400, 499 and 500 on news, with the 401 and 404 bodies shown only as examples (9 of 15). Versioned paths (/api/v2) and three changelog pages that are empty templates (5 of 15). Total 71.

Tiingo 39

No OpenAPI document or MCP server was found (0 of 25). llms.txt and llms-full.txt are served, with product routing and licence notes (10). Each documentation page states the endpoint's purpose and timing, such as prices after 5.30 pm ET with corrections to 8 pm, with little on when not to use it (12 of 20). Parameters and response fields are tabled with names and meanings, but types, defaults and allowed values are partly in prose (8 of 15). Examples in Python, Node and PHP on every page; no error responses documented (7 of 15). A changelog dated by entry since 2017 and a one-year support commitment after breaking changes, with no version in the path (12 of 15). 0 + 10 + 12 + 8 + 7 + 12 = 39.

Payments & pricing Tiingo +30

Benzinga 0

No x402, MPP or L402 (0). No prices are published anywhere we could read; the docs say to email or call licensing and the APIs page on www.benzinga.com answered 403 (0). The FAQ says a trial or sandbox is often available, with no terms, length or card condition, and the registration page was unread (0). A person registers in a browser or by email (0). Total 0, with pricing and registration recorded as unchecked.

Tiingo 30

No x402, MPP or L402 (0). Two plan prices public without login, $0 and $30 a month, sold by requests an hour and a day rather than per call; fundamentals and commercial licences by email (10). A free Starter plan at 1,000 requests a day with no card requirement stated (20). The token comes from a browser signup, and the developer programme forbids programmatic registration (0). 0 + 10 + 20 + 0 = 30.

Transparency & trust Tiingo +13

Benzinga 44

A closed service whose terms could not be read, since www.benzinga.com answered 403; the docs footer links them (8 of 30). The privacy policy was unread for the same reason, and the docs say nothing about retention (0 of 30, unchecked). No deprecation policy or dated notices; the changelog pages are empty (0 of 20). The architecture page says the platform runs on Amazon Web Services with Kong Gateway, with no subprocessor list or data location statement (5 of 20). Total 13.

Tiingo 57

A closed service whose terms sit on app.tiingo.com, which answered 403 to every request, so they were not read; the pricing and documentation pages define internal, commercial and redistribution licences (8 of 30). The privacy policy is on the same host and was not read (0 of 30). The developer programme commits to a year of continued support after a breaking change, with changes posted in the changelog and emailed to registered developers, and the changelog's 9 October 2026 entry describes a changed default for prevClose (16 of 20). Equinix hosting is named on the about page, with no processor list or data location (4 of 20). 8 + 0 + 16 + 4 = 28.

Agent ergonomics Benzinga +9

Benzinga 65

displayOutput of headline, abstract or full sizes a news response, and pageSize runs to 100 (18 of 25). page and pageSize, ticker, channel, date and updatedSince filters, with a 10,000-item cap per query that the docs explain how to work round (18 of 20). Error bodies carry a code, an id and a message in the examples, but an unknown node ID returns 200 with an empty array and the spec's response list doesn't match the examples (10 of 20). Every data call is a read, with no safe-retry guidance; the webhook API registers endpoints (12 of 20). Few required parameters, but the Python client is from 2021, the JavaScript client from 2023 and the docs' SDK page is template text (7 of 15). Total 65.

Tiingo 56

startDate, endDate, resampleFreq, format=csv and column selection on some endpoints size responses; no field selection on end-of-day prices (15 of 25). Date ranges throughout and limit and offset on news, no cursor (15 of 20). Errors are undocumented; a missing token answered 403 with a JSON detail field in our one test call (3 of 20). Every call is a read (16 of 20). Few required parameters, but no official SDK; the docs point to third-party packages (7 of 15). 15 + 15 + 3 + 16 + 7 = 56.

Maintenance & community Benzinga +6

Benzinga 56

The docs repository had commits on 2 and 3 November 2026 moving OpenAPI specs from GitLab, and the robots.txt is versioned 11 September 2026 (30). Eight commit days between 23 October and 3 November 2026, all spec transfers, with no dated changelog entry anywhere (12 of 20). Support is licensing@benzinga.com, partners@benzinga.com and a phone line, with a status page; GitHub issue responsiveness was not read (6 of 15). The Python client's last PyPI release is 1.21 of 8 February 2021 and the JavaScript client was last pushed in July 2023, so no current official SDK (5 of 15). The Python client repository was pushed in March 2026 with no release; CI not checked (3 of 10). Total 56.

Tiingo 50

Read as a closed service. The changelog's newest entry is 9 October 2026 (30). Entries dated 9 October and 8 September 2026 fall in the last 90 days, with 21 July just outside, and the status page adds a maintenance window on 28 September (12 of 20). A dated changelog, a support address and a blog, with the developer programme promising priority email support (8 of 15). No official SDK (0 of 15). No package to assess (0 of 10). 30 + 12 + 8 + 0 + 0 = 50.

Verdicts

Benzinga

Benzinga's news, calendar and transcript APIs are documented from 11 public OpenAPI specs with an llms.txt and a Statuspage. The token travels in the query string, no prices or rate limit numbers are published, the Python client was last released in February 2021, and the vendor's main site refused our reader, so its terms and privacy policy are unread.

Tiingo

A dated changelog since 2017, a one-year support commitment after breaking changes, an Instatus status page and a free token at 1,000 requests a day. The token is documented in the URL, no OpenAPI document, error reference, SDK or MCP server exists, and the terms and privacy policy sit on a host that refused our reader.

Before you call either

Benzinga

  1. Keep the token out of logs; it can only travel as ?token=, so strip query strings before recording request URLs
  2. Page through news with page and pageSize (max 100) and narrow by tickers, dateFrom or channels; a query can't pass 10,000 items
  3. Poll with updatedSince (news) or parameters[updated] (calendar, signals) rather than re-reading history
  4. An unknown or unentitled news node ID returns 200 with an empty array, not 404; treat empty as not found
  5. Don't plan on a free key; access starts with licensing@benzinga.com and a contract

Tiingo

  1. Send the token as Authorization: Token <token>, not as ?token= in the URL
  2. Ask for format=csv on large price pulls; the docs say CSV is 4 to 5 times faster than JSON, and bandwidth counts against the monthly cap
  3. Count requests an hour and a day, not per second; 50 an hour on Starter, 10,000 on Power, reset on the hour and at midnight ET
  4. Expect 403 {"detail":"Please supply a token"} without a token; other error shapes are undocumented, so log the body
  5. Use dashes in share classes (BRK-A), and fetch supported_tickers.zip rather than guessing symbols
