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.

Maintenance & community EODHD +22

EODHD 82

Read as a closed service with open-source tooling. The MCP server's last commit is 15 October 2026 and the Claude skills repository was updated 22 October (30). Dated changes in the last 90 days include MCP commits on 8, 9 and 17 September and 9, 10 and 15 October, and the real-time feed update of 26 August 2026 (20). Pull requests on the MCP repository are merged by the vendor, support is 24/7 by email and chat per the site, and forum.eodhd.com did not resolve for us (12 of 15). Official Python and Node.js libraries; the Python package's last PyPI release is 1.0.32 of 18 December 2024, though its repository was updated in October 2026 (12 of 15). The MCP server pins fastmcp, ships tests and a security toolchain in CI (8 of 10). 30 + 20 + 12 + 12 + 8 = 82.

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.

Agent ergonomics EODHD +17

EODHD 76

The REST API is the surface graded. from, to, period, fmt, filter on fundamentals and limit on news size responses, and the hosted MCP server lists 72 or 88 tools (15 of 25). limit and offset on news and the screener, date ranges on series, bulk per exchange (15 of 20). 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.

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.

Reliability EODHD +15

EODHD 65

Read with the hosted lines. 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.

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.

Schema & documentation EODHD +9

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). Each API page states its purpose and plan, and tool titles name the dataset, with little on when not to use one (14 of 20). 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.

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.

Security & auth EODHD +9

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.

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.

Transparency & trust Financial Modeling Prep +5

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.

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.

Verdicts

EODHD

Limits, call weights, rate-limit headers, 429 with Retry-After and 402 on an exhausted allowance are documented, with an OpenAPI document and an open-source MCP server of 88 read-only tools. 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.

Financial Modeling Prep

About 199 stable REST endpoints with Markdown docs for agents, a dated changelog and a free key at 250 calls a day. The one key travels in the query string on the documented MCP address, error responses and 429 handling are undocumented, the status history could not be read, and personal plans forbid any company use.

Before you call either

EODHD

  1. 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
  2. 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
  3. 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
  4. Use {TICKER}.{EXCHANGE} symbols in upper case, such as AAPL.US or EURUSD.FOREX, and BTC-USD.CC for crypto
  5. 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

Financial Modeling Prep

  1. Send the key as an apikey header, not in the URL, and treat the MCP ?apikey= address as a secret
  2. Use the /stable paths from api-docs.md; /api/v3 and /v4 are discontinued even though the FAQ still shows a v3 example
  3. On the free plan expect 5 results and page 0 on many list endpoints; read pricing.md before planning a crawl
  4. A missing or wrong key returns HTTP 401 with an Error Message field; stop and ask the user rather than retry
  5. Do not display or pass on the data in a product; personal plans forbid it
