Why the edge:
- Agent ergonomics, Databento +32: Databento 80 (`limit`, time ranges to the nanosecond, schema choice from trades to daily bars, encoding choice and `metadata.get_cost` to size a request before paying (20 of 25). Symbol, date and schema filters, batch jobs listed and fetched by id, no cursor pagination because ranges are split by time (16 of 20). Errors carry an HTTP code, a named identifier, a message and a docs link, with 206 for partially resolved symbols (17 of 20). Reads only on the historical and reference APIs; a duplicate streaming request is charged twice, batch is billed once, and the portal can cap monthly spend (12 of 20). Few required parameters, and official clients in Python, C++ and Rust (15). Total 80.); 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.)
- Security & auth, Databento +26: Databento 61 (Named API keys, up to 100 per account, rotated or deleted in the portal, with per-member permissions, sent only as the Basic auth username; no scopes per key and no expiry (25 of 30). Every API call is a read, and a monthly historical limit caps what a leaked key can spend; live usage is not capped (14 of 20). The API returns market data and reference records, not free text from third parties (10). A data usage page in the portal and a billing page per cycle, with no per-key call log documented (8 of 15). The vendor revokes keys it finds in public and documents key hygiene; security.txt returns 404 and no bounty, SOC 2 or ISO 27001 was found on readable pages (4 of 20). Total 61.); Eulerpool Financial Data API 35 (One API key per account, revocability not stated (20), less 10 because `?token=` in the URL is documented as the first option (10 of 30). Read-only data (15 of 20). News, earnings-call transcripts and AI-generated SWOT text are returned with no prompt-injection guidance (5 of 15). Quota headers on each response; no usage log found (5 of 15). No security.txt check, disclosure policy, bug bounty or certification found (0 of 20). 10+15+5+5+0 = 35.)
- Schema & documentation, Databento +22: Databento 75 (No OpenAPI document was found. The contract is the per-endpoint reference with typed parameters, the DBN schemas with field tables and enums, and a .http.md variant of every page (8 of 25). llms.txt and a Markdown twin of every page with language variants (10). Endpoint pages say what each call returns and the basics pages say when to use streaming against batch (15 of 20). Typed parameters with enums for schema, encoding, symbology type and split duration (13 of 15). Code in Python, C++, Rust and curl on every page, and an error table with codes, named error identifiers and a docs link in each body (14 of 15). Semantic versioning with dated release notes per component, breaking changes and deprecations called out (15). Total 75.); 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.)
- Payments & pricing, Eulerpool Financial Data API +18: Databento 22 (No x402, MPP or L402 (0). Plans are public ($199, $1,750 and $4,500 a month) and historical data is metered per GB, but the per-dataset rates are in the portal catalogue behind a login and the pricing page's estimator shows only an example (12 of 20). $125 of credits for every new user, expiring after six months; whether a card is needed at signup was not found on the pricing, credits or billing pages (10 of 20). A person signs up in a browser and creates keys in the portal; no key API (0). Total 22.); 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.)
- Maintenance & community, Databento +14: Databento 84 (Python 0.89.0 on 28 October 2026 and data release notes dated 20 October (30). Python 0.85.0 (25 August), 0.86.0 (1 September), 0.87.0 (22 September), 0.88.0 (21 October) and 0.89.0, plus Rust 0.64.0 and C++ 0.69.0 on 27 October and four dated data notes since 8 August (20). A Slack community, Intercom chat, support@databento.com, a public roadmap and a public issue tracker linked from the release notes; GitHub issue replies were not read because the GitHub API rate limit was reached (12 of 15). Official clients in Python, C++ and Rust released the same week as each other (15). The Python client is Apache-2.0 with releases on GitHub and PyPI; CI and dependency pins were not checked (7 of 10). Total 84.); 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.)
- Reliability, Databento +10: Databento 50 (Graded as a hosted service. Atlassian Statuspage at status.databento.com with ten components, Portal, Historical, FTP and seven live feeds (20). The incident feed for the 90 days to 3 November 2026 lists a critical outage of the portal and Historical API on 6 August lasting about eight hours, critical live authentication timeouts in NY4 on 28 August for about seven hours, major batch job delays of about two days each opened on 6 and 12 October, a six-hour GLBX.MDP3 delay in the Historical API on 6 October, and a Frankfurt outage affecting XEUR and XEEE opened on 2 November and still in monitoring. Several majors (0 of 30). Per-IP limits are published with numbers (15). 429 with a Retry-After header and a code to sleep on it; streams cut off aren't billed for unsent data, batch jobs are billed once (15). No SLA found; the pricing page names none and the terms were unreadable (0). The HTTP API is at major version 0 and the docs say it is not considered stable (0 of 10). Total 50.); 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.)
