A public status page exists at uptime.eodhistoricaldata.com, an UptimeRobot page announced on the blog on 27 March 2020 (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, 20 calls a day free, 100,000 a day on paid plans, 1,000 requests a minute, with call weights per endpoint (15). 429 carries Retry-After, X-RateLimit headers report the ceiling, and 402 marks an exhausted allowance; reads only (15). The terms promise commercially reasonable efforts and no SLA, with SLAs sold by sales (0). The core API is generally available, with several newer APIs marked beta (10). 20 + 5 + 15 + 15 + 0 + 10 = 65.\n- 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.\n\n### Security \u0026 auth: Twelve Data +15\n\n- EODHD (39): One token per account with no scopes, shown as `api_token=` in the query string on every docs page, with a Bearer header allowed per llms.txt; the MCP v1 address embeds the token and v2 uses OAuth 2.1 with one scope, full-access (20 less 10 for the query string, so 10). All REST calls read; three MCP report tools trigger provider-side report generation and email (14 of 20). News and sentiment are third-party text and no guidance was found (5 of 15). A usage endpoint and dashboard show calls spent, not a per-call log (6 of 15). No security.txt, disclosure policy, bug bounty or certification found; the MCP server's CI runs Bandit, Semgrep and pip-audit (4 of 20). 10 + 14 + 5 + 6 + 4 = 39.\n- 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.\n\n### Transparency \u0026 trust: Twelve Data +15\n\n- EODHD (52): A closed, proprietary API under terms that name the entity and the personal and professional user classes but carry no date and no governing law; the MCP server and OpenAPI document are MIT (15 of 30). The privacy policy is undated, keeps data while the account is active with no periods, names Google only, and no DPA was found; the MCP server's telemetry is disclosed in its README (8 of 30). No deprecation policy; Exchange Details v1 was kept when v2 shipped, and new APIs are dated on the blog (5 of 20). No subprocessor list or data locations beyond Google as an advertising platform (2 of 20). 15 + 8 + 5 + 2 = 30.\n- 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.\n\n### Schema \u0026 documentation: Twelve Data +13\n\n- EODHD (70): An OpenAPI 3.1 document in a public repository covers 74 endpoints, last updated 18 February 2026, and the MCP server's 88 tools carry typed inputs and annotations in the source (22 of 25). llms.txt of 32 KB and an llms-full.txt, plus documentation resources inside the MCP server (10).

Parameters are documented with formats and the symbol convention is spelled out, but allowed values sit in prose (8 of 15). Examples on every API page and the demo token, with 401, 402, 403, 404, 422 and 429 documented in llms.txt and the limits article (11 of 15). Exchange Details v2 shipped in May 2026 with v1 kept, MCP has v1 and v2, and new APIs are announced on a dated blog, but there is no changelog page (5 of 15). 22 + 10 + 14 + 8 + 11 + 5 = 70.\n- 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).

Error codes an agent can branch on, 402 and 403 with meanings, and the MCP server answers 403 with what the plan covers (15 of 20). Every REST call is a read; 85 of 88 MCP tools carry readOnlyHint true and the three Praams report tools are marked otherwise (16 of 20). Few required parameters and official Python and Node.js libraries, with R, C# and PHP clients (15). 15 + 15 + 15 + 16 + 15 = 76.\n- 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).

The token is documented in the query string, the MCP v1 address embeds it, the status page could not be read, and the terms carry no date, SLA or governing law.\n\n**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.\n\n## Before you call either\n\n### EODHD\n\n1. Send the token as `Authorization: Bearer`, which llms.txt allows, rather than `api_token=` in the URL, and prefer the v2 OAuth MCP address over v1\n2. Budget calls, not requests; fundamentals cost 10, intraday and news 5, bulk 100 or more, and a 404 for a bad ticker is still charged, so resolve tickers with the search endpoint first\n3. Read `X-RateLimit-Remaining` and honour Retry-After on 429; a 402 means the daily allowance is gone until midnight GMT and no retry will help\n4. Use `{TICKER}.{EXCHANGE}` symbols in upper case, such as AAPL.US or EURUSD.FOREX, and `BTC-USD.CC` for crypto\n5. Expect 20 calls a day and one year of history on the free plan; a 403 means the plan lacks the endpoint, not a bad key\n\n### Twelve Data\n\n1. Send the key as `Authorization: apikey \u003ckey\u003e`, not in the URL; the hosted MCP server takes OAuth only, so never paste a key into a connector's key field\n2. 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`\n3. 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\n4. A 403 means the key's plan lacks the endpoint or symbol, not a bad key; check pricing.md before escalating\n5. Use trial symbols from twelvedata.com/exchanges to test premium data on the free plan\n\n## Questions\n\n### Which is better for AI agents, EODHD or Twelve Data?\n\nTwelve Data scores 70 (BB) on agent readiness against EODHD's 59 (C), and leads in 5 of 7 scored categories.\n\n### Do EODHD and Twelve Data need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call EODHD and Twelve Data without installing anything?\n\nYes. EODHD has a hosted endpoint at https://eodhd.com/api and Twelve Data at https://api.twelvedata.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/eodhd-vs-twelve-data.json, and with the fewest tokens: https://www.anchorterminal.com/compare/eodhd-vs-twelve-data.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"eodhd\", \"b\": \"twelve-data\"}`.
