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.

Agent ergonomics EODHD +28

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.

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.

Reliability EODHD +25

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.

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 EODHD +17

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.

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.

Maintenance & community EODHD +12

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.

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.

Payments & pricing Eulerpool Financial Data API +10

EODHD 30

No x402, MPP or L402 (0). Plan prices are public without login, personal and commercial, sold by the month with daily call allowances and per-endpoint call weights rather than per call (10). A free plan at 20 calls a day with no card (20). The token comes from a browser signup and no key API was found (0). 0 + 10 + 20 + 0 = 30.

Eulerpool Financial Data API 40

No x402, MPP or L402 (0). Plan prices and overage per 1,000 requests are public (20). 100,000 free requests a month with no card, non-commercial (20). A person registers in a browser (0). 0+20+20+0 = 40.

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.

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

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

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
