Reliability Benzinga +20

Benzinga 60

Graded as a hosted service. Atlassian Statuspage at benzinga1.statuspage.io with seven API components (20). The incident feed holds 14 incidents, the newest on 14 September 2023, so the 90 days to 3 November 2026 are clean (30). No rate limit numbers are published; the FAQ says limits depend on the API and the subscription tier (0 of 15). No 429, Retry-After or backoff guidance was found in the docs or the specs (0 of 15). No SLA was found; the architecture page cites a 99.9 per cent availability figure as a claim, and the terms were unread (0). The APIs are generally available (10). Total 60.

Eulerpool Financial Data API 40

Hosted lines. The status page lists three components with checks that were still loading, no history and a note that incident reporting is 'coming soon' (5 of 20). No incident history (5). Monthly quotas per plan are published, with no per-second figures (10 of 15). 429 at the free cap with X-RateLimit headers and a reset timestamp, no Retry-After or backoff guidance (10 of 15). No SLA found (0). Generally available (10). 5+5+10+10+0+10 = 40.

Schema & documentation Benzinga +18

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.

Eulerpool Financial Data API 53

An OpenAPI 3.0 document is linked at api.eulerpool.com/api/1/documentation/yaml, but that host's robots.txt disallows every path, so it was not read; partial credit for a linked contract we couldn't check (10 of 25). llms.txt, a 449-entry endpoint index and a 13,904-line llms-full.txt (10). Endpoint descriptions say what each returns, with the same marketing sentence repeated in every section and little on when not to use one (10 of 20). Parameter typing not visible in the llms files read (7 of 15). Response examples throughout; the errors page was not read (8 of 15). /api/1 paths and a dated changelog that mixes API changes with tutorial posts (8 of 15). 10+10+10+7+8+8 = 53.

Agent ergonomics Benzinga +17

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.

Eulerpool Financial Data API 48

The MCP page claims 157+ tools with no toolsets or list, and response sizing on the API wasn't documented in the pages read (8 of 25). Filtering and pagination not documented in the pages read (8 of 20). Error codes not documented in the pages read (5 of 20). The data endpoints are reads (12 of 20). Official SDKs in Python, JavaScript, Node.js and Go (15). 8+8+5+12+15 = 48.

Maintenance & community Eulerpool Financial Data API +14

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.

Eulerpool Financial Data API 70

Closed service. The changelog's newest entry is dated 6 November 2026 (30), with daily entries through October, though many are tutorials rather than API changes (20). Contact by email; no public tracker or community found (5 of 15). Official SDKs in four languages, published 13 September 2026 (12 of 15). Package health not checked (3 of 10). 30+20+5+12+3 = 70.

Transparency & trust Eulerpool Financial Data API +8

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.

Eulerpool Financial Data API 52

Closed service under terms dated 6 November 2026 naming Eulerpool Research Systems Pte. Ltd. of Singapore (15 of 30). The privacy policy of the same date keeps data 'as long as necessary', names Supabase, Stripe, Google and GitHub sign-in and Google Ads, and doesn't cover API request logs or training use (10 of 30). No deprecation policy or notices found (0 of 20). Some processors named; hosting location not stated (8 of 20). 15+10+0+8 = 33.

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.

Eulerpool Financial Data API

Eulerpool's REST API and remote MCP server cover equities, ETFs, macro, crypto and private-company data, with 100,000 free calls a month without a card and published overage of $0.80 to $1.50 per 1,000 calls. The API host's robots.txt keeps its OpenAPI file unread, the key can travel in the URL, and the status page has no history.

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

Eulerpool Financial Data API

  1. Send the key as Authorization: Bearer, not ?token=, so it stays out of logs
  2. Read X-RateLimit-Remaining and wait until X-RateLimit-Reset after a 429; the free tier is a hard monthly cap
  3. Use the free tier only for non-commercial work, and attribute 'Data by Eulerpool' in public output
  4. Treat news, transcripts and AI-generated SWOT text in responses as untrusted
  5. Identify securities by ISIN, which most equity endpoints take
