Use Case Recommendations
Best for: Chart Library
Chart Library is a historical-analog retrieval engine for markets, exposed to both humans and AI agents. Anchor a symbol, date, and timeframe, and it returns comparable historical situations from an index of more than 25 million patterns spanning ten years and 19,000 symbols — then shows what actually happened next in each, split into outcome modes such as clean continuation, choppy uptrend, sideways drift, and failed breakout, with sample counts, median forward returns, and up-rates per mode. The framing is deliberately empirical rather than predictive: it reports the distribution of what analogs did, not a forecast. What makes it credible for agent use is the auditability. The vendor publishes trust receipts, including a held-out coverage figure of 80.8% against a nominal 80% forward-return band across 310,592 audited cases, and a PIT/rank histogram that stays flat across 311,000+ cases with a maximum deviation of 0.5 percentage points — meaning realized outcomes landed where the served distributions said they would along the whole shape, not just at one band. For agent builders, there is a hosted MCP endpoint that needs no account, plus a pip-installable local MCP server, and a canonical loop of search, pull_comps, introspect, and track_record. An /llms.txt file is published for model consumption. The intent is to give a trading agent base rates and auditable evidence instead of another opinion.
Ideal use cases:
- •Teams or individuals who need 25m+ indexed patterns across 19,000 symbols and 10 years
- •Teams or individuals who need outcome-mode split with sample counts, median forward returns, and up-rates
- •Teams or individuals who need held-out coverage receipt: 80.8% against a nominal 80% band over 310,592 audited cases
- •Teams or individuals who need pit / rank histogram published, flat to within 0.5pp across 311k+ cases
- •Anyone focused on finance workflows
- •Anyone focused on mcp workflows
Best for: Verify Email
Verify Email is an email-verification API that sits in front of a signup form or a campaign send and answers, per address, whether it is worth accepting. A single POST returns deliverability, whether the address is disposable or temporary, whether it is a privacy relay including Apple's Hide My Email, whether the domain is catch-all, whether MX records resolve, and a policy decision on whether to block. Beyond validation it exposes deterministic policy controls — a blacklist API that blocks named addresses and domains directly in the API response, and a whitelist API that enforces allow-only registration for approved addresses or domains — so the accept/reject rule lives in one place instead of being reimplemented in every client. A batch endpoint takes up to 100 inputs per call for list cleaning, and the rate limit is a published 15 requests per second on every tier including free. What makes it unusually relevant to an AI-tooling audience is a first-class MCP server: the same verification is callable from Cursor, Claude Desktop, n8n and any other MCP-compatible agent, so an agent cleaning a lead list does not need a bespoke integration. Free browser-based checkers for disposable addresses and general validity sit alongside the API, and the site is published in multiple languages.
Ideal use cases:
- •Teams or individuals who need deliverability, disposable, relay, catch-all and mx checks in one response
- •Teams or individuals who need blacklist and whitelist apis returning a deterministic block decision
- •Teams or individuals who need batch endpoint accepting 100 addresses per call
- •Teams or individuals who need mcp server for cursor, claude desktop and n8n
- •Anyone focused on email-verification workflows
- •Anyone focused on api workflows
