Eulerpool vs Twelve Data

Twelve Data prices in "API credits" consumed per minute, and a single call can cost 1 to 200 credits depending on the endpoint — you have to budget credits per endpoint. Eulerpool counts plain requests against a monthly quota (10,000 free, 100,000 on Builder), so cost is predictable regardless of which endpoints you call.

Twelve Data's fundamentals (statements, estimates) are reserved for its higher tiers. Eulerpool includes full income statements, balance sheets, cash flows, and ratios starting at the Builder plan ($99/month), and core financials even on the free tier.

Twelve Data has no native MCP (Model Context Protocol) server. Eulerpool ships one with 250+ tools, so Claude, Cursor, ChatGPT and other MCP clients query financial data with a single config block — no custom tool wrappers.

Congress trading, insider transactions (SEC Form 4 + EU directors' dealings), superinvestor 13F portfolios, short interest, earnings call transcripts, ETF look-through holdings, and macro series from FRED, ECB, Eurostat, IMF and the World Bank.

No. Both are JSON REST APIs. The main difference is addressing (Eulerpool is ISIN-native with ticker support) and no credit bookkeeping. The 10,000-request free tier is enough to port and validate a typical integration before switching.
