Why the edge:
- Reliability, Twelve Data +33: Financial Modeling Prep 50 (Read with the hosted lines. A public status page at status.financialmodelingprep.com is linked from every page (20), but its figures load by script and our reader got an error, so no incident history could be read (5). Limits are published with numbers, 250 calls a day on Basic and 300, 750 and 3,000 calls a minute on paid plans, with bandwidth caps per plan (15). No 429 behaviour, Retry-After or backoff guidance was found in the docs, api-docs.md or FAQs (0). No SLA found; the terms let FMP change limits without notice (0). The stable API is generally available (10). 20 + 5 + 15 + 0 + 0 + 10 = 50.); 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.)
- Agent ergonomics, Twelve Data +25: Financial Modeling Prep 59 (The REST API is the surface graded. `limit` and `page` on list endpoints, `from` and `to` on series, and batch quote endpoints size responses, with no field selection (15 of 25). Page and limit parameters on lists and date filters on series, no cursor (15 of 20). A missing key returned 401 with an `Error Message` text field in our one test call, and no error reference exists (5 of 20). Every call is a GET read; the MCP server's annotations were not read (16 of 20). Few required parameters and sensible defaults, but no official SDK in any language (8 of 15). 15 + 15 + 5 + 16 + 8 = 59.); 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 +24: Financial Modeling Prep 30 (One key per account with no scopes, accepted as a header or as `?apikey=`, and the documented MCP address carries it in the URL (20 less 10 for the query string, so 10). Every endpoint is a read (15 of 20). News, press releases, transcripts and filings are third-party text and no guidance on treating them as untrusted was found (5 of 15). No usage log or per-call record for the key holder was found (0 of 15). security.txt returns 404, the Trust Center link returns 404, and no disclosure policy, bug bounty or certification was found (0 of 20). 10 + 15 + 5 + 0 + 0 = 30.); 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.)
- Schema & documentation, Twelve Data +22: Financial Modeling Prep 61 (No OpenAPI document was found. The MCP page says the server supplies strict parameter definitions, but the tool list needs a key and was not read (5 of 25). llms.txt links api-docs.md and pricing.md, Markdown written for agents (10). Each of the 199 endpoints in api-docs.md has a purpose paragraph and a plan marker in pricing.md, with little on when not to use it (13 of 20). Parameters are tabled with type, example and a required star, but allowed values sit in prose and no enums are given (8 of 15). Every endpoint has an example request and response; no error responses are documented anywhere we read (10 of 15). A /stable path, legacy /v3 and /v4 marked discontinued, and a changelog dated by day through 2 November 2026 (15). 5 + 10 + 13 + 8 + 10 + 15 = 61.); Twelve Data 83 (A public OpenAPI 3.1 document covers 187 operations, every one with a description and 200, 400, 401, 403, 404, 414, 429 and 500 responses, and the MCP tools in the source carry typed inputs and annotations (25). llms.txt on the site and in the docs link Markdown pages per section, pricing.md and auth.md (10). Descriptions state purpose, plan requirement and credit cost, with little on when not to use an endpoint (16 of 20). Required parameters are marked and the Markdown lists interval, adjust and type values, but none of the 3,091 parameters in the spec declares an enum (9 of 15). Examples with a demo key on every endpoint and an error table with codes and meanings (13 of 15). No version in the path, a spec at version 0.0.1, and monthly dated product updates on the news page rather than an API changelog (10 of 15). 25 + 10 + 16 + 9 + 13 + 10 = 83.)
- Maintenance & community, Twelve Data +22: Financial Modeling Prep 60 (Read as a closed service. The changelog's newest entry is 2 November 2026 (30). Entries dated 6, 8, 12, 28 and 29 October and 2 November 2026, more than three in 90 days (20). A public changelog, a help centre, FAQs and a support address, with issues reported through a site chatbot per the FAQ (10 of 15). No official SDK; the FAQ points at third-party packages (0 of 15). No package to assess, and nothing else to show for CI or dependency health (0 of 10). 30 + 20 + 10 + 0 + 0 = 60.); 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.)
- Transparency & trust, Twelve Data +10: Financial Modeling Prep 57 (A closed service under terms that are clear on personal and commercial use and on display licensing, last updated 1 August 2023, but that name no legal entity, address or governing law (12 of 30). The privacy policy is undated, keeps data for as long as necessary with no periods, says no third parties receive data while naming Google AdSense and Analytics, and no DPA was found (8 of 30). The docs keep a Legacy section and api-docs.md says /v3 and /v4 are discontinued, with no notice period stated; behaviour changes such as the Economics Indicators default window appear in the dated changelog (8 of 20). Google services are the only processors named and no data location is given (5 of 20). 12 + 8 + 8 + 5 = 33.); 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.)
