Alphanume
Proprietary, agent-ready market data

Give your agent data
with evidence behind it.

Alphanume publishes proprietary, point-in-time market datasets your agent can query, test, and turn into quantitative strategies. Connect Claude or Codex with one URL and a sign-in, get full history, live updates, REST access, and public proof of the market effect behind every tested dataset.

Prompt

Find optionable stocks where implied volatility is unusually rich versus realized volatility. Combine that with the current risk regime and next-day movement candidates. Then write a point-in-time test with no future leakage.

The evidence

We test the data against what happened next.

Every study uses Alphanume observations as they were available at the time. Strong results, weak links, proxy limitations, and gross-versus-net caveats are reported on the same page.

Three examples

Different datasets. Measurable effects.

  • Stock Dilution

    Median -14.9% at one month.

    Across the reported study, 71% of dilutive filings were lower one month later (z = 8.9), with a stronger effect in smaller companies.

  • Earnings Implied vs Realized

    The implied move exceeded the realized move 64% of the time.

    The published study reports a gross edge of 1.1% of spot per event (t = 10.4). Costs, slippage, and path risk still matter.

  • IV/HV Premium

    A 14.5-vol-point spread across reported quintiles.

    The seller edge sorted monotonically from -9.4 to +5.1 vol points as implied volatility became richer versus realized volatility.

These studies establish historical market effects under the stated methodology. They are not expected returns, personalized advice, or a guarantee that an effect survives costs or future regimes.

  1. 01

    Add the connector and sign in

    Paste the Alphanume server URL into Claude or Codex and sign in with your Alphanume account. No API key to copy, no headers to configure, no client that needs to support them.

  2. 02

    Ask a research question

    Use plain language. The agent picks the tools and constructs the calls across volatility, events, market regimes, attention, and point-in-time reference data; Alphanume returns deterministic rows with dates and definitions.

  3. 03

    Inspect the evidence and run the test

    Generate code, confirm timestamps and coverage, compare the result with the published study, and move the same data contract into a live internal workflow.

The data

Start with the market question, not the endpoint name.

New datasets are added continuously under the same account, authentication, and delivery model.

Why Alphanume

Data you can defend in a research review.

  1. 01

    Point-in-time by default

    Observations are stamped as they became available. Fixed history prevents a silent revision or today's universe from leaking into yesterday's test.

  2. 02

    Constructed from primary sources

    Alphanume turns raw filings, market observations, and model inputs into research-ready event histories and signals. Dataset pages state what came from the source and what Alphanume created.

  3. 03

    Evidence attached

    Each tested dataset links to the sample, period, test, result, and caveats. Nuanced findings remain visible instead of disappearing from the catalog.

  4. 04

    One consistent interface

    Use the same key across the dashboard, REST API, and hosted MCP server. Add a new signal without a new vendor integration.

Common questions

The answers a buyer actually needs.

Can I use Pro in a live trading workflow?
Yes. Pro is the self-serve plan for one named user and may be used for that user's research, backtests, automation, and internal live trading. Choose Enterprise when you need multiple users or keys, redistribution or client-facing rights, custom delivery, an SLA, or organization-specific contract terms.
What makes the datasets proprietary?
Alphanume constructs datasets from primary sources and its own models rather than simply reselling a standard market feed. Each dataset page identifies the source inputs, the fields or labels Alphanume created, the observation-time policy, update cadence, and historical coverage.
Does every dataset have proof?
Every dataset has a documented methodology and point-in-time contract. Tested datasets also link to a public market-effect study. The Proof page reports strong and nuanced findings alike rather than labeling every result a success.
How does agent access work?
Add https://mcp.alphanume.com/mcp as a custom connector in Claude or Codex and sign in with your Alphanume account. There is no key to copy and no separate MCP subscription: sign-in resolves the key already on your account, so your tier and limits match the REST API exactly. Cursor, scripts, and CI use a key endpoint instead. The agent chooses the tools and parameters; Alphanume returns the same deterministic dataset rows available through REST.
Are new datasets included in Pro?
New standard Alphanume datasets are included in Pro as they launch. Separately licensed third-party data, custom datasets, bulk delivery, and organization-specific rights may require Enterprise.
Are these trade recommendations?
No. Alphanume provides data, models, and historical research for quantitative workflows. The published studies describe historical effects under stated assumptions; they are not personalized recommendations or guarantees of future performance.
