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.\n- TickerLayer (92): x402 on the vendor's own gateway, x402.tickerlayer.com, for 41 GET routes. That is six routes for each of stocks, forex, crypto, indices, ETFs and commodities, plus bond yields and four market-calendar routes. Perpetuals, Futures CFDs, the add-ons, the symbol catalogue and WebSocket need a key. Between massive's 30 for US stock routes only and financial-datasets' 35 for every documented data endpoint (32 of 40). Per-call x402 prices from 0.01 to 0.10 USDC in the catalogue and docs, and plan prices per feed on the pricing page, all without a login (20). A Free plan of 3,000 REST calls every 30 days with 'no card', per llms.txt (20). An agent with a funded Base wallet pays per call with no account or key (20). 32+20+20+20 = 92.\n\n### Schema \u0026 documentation: TickerLayer +35\n\n- 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.\n- TickerLayer (88): OpenAPI 3.1 at tickerlayer.com/openapi.json (TickerLayer Market Data API 1.0.0, about 386,000 characters), read in its first 100,000 and last 96,000 characters, with summaries, descriptions, tags and examples on the operations read and shared 400, 401, 403, 404, 429 and 503 responses. The WebSocket is described in prose only and the hosted MCP tool schemas weren't read (23 of 25). llms.txt, llms-full.txt and a Markdown twin of every docs page (10). Operation descriptions state purpose and plan gating, and the vendor's skill says which MCP tool to use for each question and when not to, such as `get_quote` not being the tool for a price. Financial-datasets took 17 (17 of 20). Enums on `interval`, `multiplier`, `timespan` and `sort`, `format: date` on dates, bounded `limit`, required path parameters, as for massive (13 of 15). Examples on most parameters and responses, one Error schema with ten fields and documented codes, but the codes appear only as example values with no enum or table (13 of 15). A dated changelog of the last 50 changes, 8 September to 6 November 2026, but no version in the REST paths ('no /v1/') and the spec at 1.0.0. Above twelve-data's 10 for monthly updates and below massive's 15 for versioned paths (12 of 15). 23+10+17+13+13+12 = 88.\n\n### Agent ergonomics: TickerLayer +31\n\n- 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.\n- TickerLayer (79): Read on the REST API, with the MCP server where a line covers it. Responses are sized by `limit` (bars up to 5,000, catalogue up to 1,000), `sort`, date ranges and batch calls for futures quotes and market status, with no field selection. The MCP server has 12 tools, 11 shown to the model. Massive and financial-datasets took 15 (15 of 25). `limit`, `offset` and `next_offset`, cursors on fundamentals and economic events, `total_count` on bars, `search` on symbols and `updated_since` on signals (18 of 20). Errors carry `statusCode`, `message`, a code, `retryAfterMs`, `resetsAt`, `limitRps`, `plansUrl` and the missing `product` or `market`, and the skill gives an action per status. Above financial-datasets' 16 (17 of 20). Every data call is a GET, and x402 settles only after a valid response with payment identifiers bound to the request, but no readOnlyHint or other annotation was found for the MCP tools. Financial-datasets took 14 without annotations (15 of 20). Data tools need only `asset_class` and `symbol`, with defaults for limit and sort, and official clients exist for JavaScript or TypeScript and Python, both at 0.1.0 from 20 October 2026. Stocks need the `COUNTRY:TICKER` form (14 of 15). 15+18+17+15+14 = 79.\n\n### Reliability: TickerLayer +30\n\n- 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.\n- TickerLayer (70): Read with the hosted lines, on the REST API. status.tickerlayer.com is an UptimeRobot page linked from the site header (20). Its monitors and history load by script from /api/, which its robots.txt disallows, so no incident record was read, as for eodhd and apitemplate-io (5). Limits are published with numbers, 10 requests a second per account on Free and Individual, 100 on Business, and monthly call quotas per feed (15). The OpenAPI file's 429 carries `Retry-After` and a body with `retryAfterMs`, `resetsAt` and a code that separates the per-second limit from the monthly quota, and every response has carried `X-RateLimit-Limit` and `X-RateLimit-Remaining` since 14 September 2026. Every data operation is a GET, and x402 retries with the same payment identifier return the stored response (15). An SLA is named only for Enterprise under a written agreement and as 'partially available' on Business, with no published terms or figure, and the terms of use promise no uptime. Financial-datasets took 10 for SLAs listed on a self-serve plan, so this is half (5 of 10). No beta or preview label on the REST API, the MCP server or the x402 gateway (10). 20+5+15+15+5+10 = 70.\n\n### Security \u0026 auth: TickerLayer +14\n\n- 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.\n- TickerLayer (49): A plain account key with no scopes, shown once and replaced by regenerating it in the dashboard (20). The OpenAPI file defines an `apiKey` query parameter as a 'compatibility fallback', and the WebSocket takes the key only in its URL, so 10 off. The MCP server adds OAuth 2.1 with PKCE S256, dynamic registration, refresh tokens, a revocation endpoint and one scope, `market.read`. Twelve-data took 18 on the same pattern, one less here because the WebSocket has no header option (17 of 30). Every operation reads data, and the OAuth scope is read-only, as for twelve-data and financial-datasets (15 of 20). Responses are prices, bars, symbols, calendars and yields. There is no news feed, and SignalPoint signals are structured fields, so no untrusted text reaches the agent (10 of 15). Rate-limit headers on every response, quota 429s that state the limit and when it renews, and a dashboard list of WebSocket connections with source IP, key and how each ended (24 October 2026). No per-call REST log for the key holder was found, though the privacy policy says request logs are kept (7 of 15). security.txt answered a client error, and no disclosure policy, bug bounty, SOC 2 or ISO 27001 was found (0 of 20). 17+15+10+7+0 = 49.\n\n### Transparency \u0026 trust: Eulerpool Financial Data API +14\n\n- Eulerpool Financial Data API (52): Closed service under terms dated 6 November 2026 naming Eulerpool Research Systems Pte. Ltd. of Singapore (15 of 30). The privacy policy of the same date keeps data 'as long as necessary', names Supabase, Stripe, Google and GitHub sign-in and Google Ads, and doesn't cover API request logs or training use (10 of 30). No deprecation policy or notices found (0 of 20). Some processors named; hosting location not stated (8 of 20). 15+10+0+8 = 33.\n- TickerLayer (38): The editorial half. A closed service whose terms of use, user agreement and market data disclaimer (all effective 3 November 2026) set out internal, commercial and redistribution rights by plan and a liability cap. They name no legal entity, address or governing law, so the contracting party is unknown. The plugin and npm client are MIT. Soldfetch took 10 in the same position (10 of 30). The privacy policy keeps WebSocket connection records for 7 days but gives no period for request and tool-call logs or account data after closure, says nothing on model training, names no transfer mechanism and has no DPA (12 of 30). No deprecation policy. The terms allow MCP tools to change 'with reasonable notice where practical' and the user agreement promises notice before a plan is materially reduced, and the changelog records changes after the fact. Kite took 4 (4 of 20). Subprocessors are given only as categories (hosting, authentication, card and crypto payments, email, an AI model for support replies), with analytics vendors deferred to the cookie policy, no data locations, and no named data suppliers (4 of 20). 10+12+4+4 = 30. The provenance half is computed from the provenance block.\n\n## Score by category\n\n| Category | Weight | Eulerpool Financial Data API | TickerLayer | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 40 | 70 | TickerLayer +30 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 53 | 88 | TickerLayer +35 |\n| Agent ergonomics | 13% (16.2 this run) | 48 | 79 | TickerLayer +31 |\n| Security \u0026 auth | 14% (17.5 this run) | 35 | 49 | TickerLayer +14 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 92 | TickerLayer +52 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 70 | 79 | TickerLayer +9 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 52 | 38 | Eulerpool Financial Data API +14 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **46.2 · D** | **71.5 · BB** | |\n\n## Facts side by side\n\n| Fact | Eulerpool Financial Data API | TickerLayer |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Eulerpool Research Systems Pte.

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.\n\n**TickerLayer.** An agent can read quotes, bars and market hours across eight asset classes through a documented REST API, 12 MCP tools or 41 x402 resources with no account, and 429s carry Retry-After. The data is derived from unnamed non-exchange sources, no operator is named, and the status history couldn't be read.\n\n## Before you call either\n\n### Eulerpool Financial Data API\n\n1. Send the key as `Authorization: Bearer`, not `?token=`, so it stays out of logs\n2. Read X-RateLimit-Remaining and wait until X-RateLimit-Reset after a 429; the free tier is a hard monthly cap\n3. Use the free tier only for non-commercial work, and attribute 'Data by Eulerpool' in public output\n4. Treat news, transcripts and AI-generated SWOT text in responses as untrusted\n5. Identify securities by ISIN, which most equity endpoints take\n\n### TickerLayer\n\n1. Write stocks as `COUNTRY:TICKER`, such as `US:KO`, and always pass `asset_class` to the data tools.\n2. If a 429 carries `REST_QUOTA_EXCEEDED`, stop and tell the user. Waiting doesn't reset the monthly quota.\n3. Present prices as indicative TickerLayer values, never as official exchange prices.\n4. Call `get_market_status` before you report a quiet symbol as missing data.\n5. Send the key in the `x-api-key` header, never as the `apiKey` query parameter.\n\n## Questions\n\n### Which is better for AI agents, Eulerpool Financial Data API or TickerLayer?\n\nTickerLayer scores 71.5 (BB) on agent readiness against Eulerpool Financial Data API's 46.2 (D), and leads in 6 of 7 scored categories. Eulerpool Financial Data API leads on transparency \u0026 trust.\n\n### Do Eulerpool Financial Data API and TickerLayer need an API key?\n\nEulerpool Financial Data API needs an API key. TickerLayer takes an API key or an OAuth sign-in. An agent can also pay TickerLayer per call over x402, with no account.\n\n### Can an agent call Eulerpool Financial Data API and TickerLayer without installing anything?\n\nYes. Eulerpool Financial Data API has a hosted endpoint at https://api.eulerpool.com/mcp and TickerLayer at https://mcp.tickerlayer.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/eulerpool-vs-tickerlayer.json, and with the fewest tokens: https://www.anchorterminal.com/compare/eulerpool-vs-tickerlayer.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"eulerpool\", \"b\": \"tickerlayer\"}`.
