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.

Payments & pricing Twelve Data +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.

Twelve Data 30

No x402, MPP or L402 (0). Plan prices are public without login in pricing.md and on the pricing page, sold by credits a minute per month rather than per call (10). A free Basic plan at 800 credits a day with no card (20). The key comes from a browser signup and no key API was found; MCP needs an OAuth login by a person (0). 0 + 10 + 20 + 0 = 30.

Maintenance & community Twelve Data +26

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.

Twelve Data 82

Read as a closed service. The newest dated change is the product update of 12 October 2026, with the MCP repository changed on 1 October and the world-model dataset repository on 31 October (30). Monthly updates dated 12 August, 12 September and 12 October 2026 (20). A monthly changelog, a support portal, a sales contact and a Telegram channel; replies on the MCP repository's issues were not read (10 of 15). Six official SDKs and a CLI, twelvedata-python at v1.4.0 of 27 April 2026 (15). The MCP server pins its dependencies with reasons and ships tests; the Python SDK's changelog stops at version 0.1 (7 of 10). 30 + 20 + 10 + 15 + 7 = 82.

Reliability Twelve Data +23

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.

Twelve Data 83

Read with the hosted lines. A public status page at twelvedata.isitup.cloud lists Price API, Fundamentals API, WebSocket and Website with uptime figures (20). Its history shows two incidents in the 90 days to 3 November 2026, 20 minutes of unavailability across the three APIs on 1 September and 16 minutes on the WebSocket on 14 October, minor only (20). Limits are published with numbers, credits a minute by plan from 8 to 10,946 and 800 a day on Basic (15). The docs document a 429 on the limit and the usage endpoint, with no Retry-After or backoff guidance; reads only (8 of 15). The terms sell a 99.9 per cent SLA with service credits, and the Enterprise plan carries 99.99 per cent (10). The REST API and MCP server are generally available (10). 20 + 20 + 15 + 8 + 10 + 10 = 83.

Transparency & trust Twelve Data +23

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.

Twelve Data 67

A closed service under terms that name the entity, define internal use, business use and redistribution, and were last updated 1 January 2026; the MCP repository is open source but ships no licence file (15 of 30). The privacy policy of 22 September 2026 states retention periods and names its processors, the terms require data deletion within 30 days of termination, and no DPA is named (20 of 30). No deprecation policy or notice period; the terms allow changes and the monthly updates record them after the fact (3 of 20). Subprocessors are named on the privacy policy and the trust centre, with no data locations beyond transfer mechanisms (12 of 20). 15 + 20 + 3 + 12 = 50.

Agent ergonomics Twelve Data +19

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.

Twelve Data 84

The REST API is the surface graded. outputsize 1 to 5,000 with a default of 30, format=CSV, dp, date ranges and batch requests size responses, and the MCP server lists 27 tools (20 of 25). Date ranges, outputsize and exchange, country and type filters, with no cursor pagination (15 of 20). Error codes with meanings an agent can branch on, 403 for plan limits and 429 for credits (16 of 20). Every operation is a read, and the MCP source marks tools readOnlyHint (18 of 20). Few required parameters, a demo key, and official SDKs in Python, Node.js, Go, Java and R (15). 20 + 15 + 16 + 18 + 15 = 84.

Security & auth Twelve Data +18

Benzinga 36

One token per account with no scopes, sent only as the token query parameter, generated in the console; no rotation or expiry found (20 less 10 for the query string, so 10). Every data endpoint is a read (15 of 20). News, press releases and transcripts are third-party text, with no guidance on treating them as untrusted (5 of 15). No usage log or per-call record for the token holder was found (0 of 15). security.txt names security@benzinga.com and a policy page, with an Expires date of 1 June 2025, and the policy itself is on the host that refused our reader; no bounty, SOC 2 or ISO 27001 was found in the docs (6 of 20). Total 36.

Twelve Data 54

The REST key is a plain per-account key with no scopes, accepted as a header or as ?apikey= (20 less 10 for the query string). The hosted MCP server refuses keys and uses OAuth 2.1 with PKCE, a resource indicator, refresh tokens, revocation and one scope, which lifts the credential model for that surface (18 of 30). Every operation is a read (15 of 20). Company news is third-party text and no guidance was found (5 of 15). An /api_usage endpoint and dashboard usage give the key holder a view of consumption, not a per-call log (6 of 15). A trust centre on SafeBase lists SOC 2, GDPR and CCPA and ten policies; no security.txt, disclosure process or bug bounty was found (10 of 20). 18 + 15 + 5 + 6 + 10 = 54.

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.

Twelve Data

A public OpenAPI 3.1 document with error responses on all 187 operations, Markdown docs and pricing for agents, a status page with two short incidents in 90 days, and an MCP server behind OAuth 2.1. The REST key still travels in the query string as a documented option, no enums are declared, and free and individual plans forbid company use.

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

Twelve Data

  1. Send the key as Authorization: apikey <key>, not in the URL; the hosted MCP server takes OAuth only, so never paste a key into a connector's key field
  2. Set outputsize (1 to 5,000, default 30) and format=CSV on time_series to keep responses small, and read status in the JSON body since errors come with HTTP codes and a message
  3. Count credits, not calls; most endpoints cost one credit per symbol and the Basic plan allows 8 a minute and 800 a day, with 429 when exceeded
  4. A 403 means the key's plan lacks the endpoint or symbol, not a bad key; check pricing.md before escalating
  5. Use trial symbols from twelvedata.com/exchanges to test premium data on the free plan
