The issuer record, as of any date, with the receipt.

As Of · on Data Vintage · Replay

get_as_of is the issuer record as it stood on a date: an issuer by ticker, ISIN or LEI plus a date returns the signed record of that day — every field with its source and read date, the sealed disclosure lines of the market-year up to that date — signed by the node of the issuer's market and receipted, so a backtest can show what it read and when. Nothing is restated and nothing is filled backwards: before the record existed the answer says before_record; in a market-year not yet sealed it says not_sealed and names the earliest sealed date.

1 What it is

1.1

Built specifically so an AI agent can read the issuer record as it stood on any date since 2021, with the proof that it read it.

1.2

Any agent gets in; it pays in the call. A firm licenses the vintage.

1.3

Sealed years, 2021 forward, done. Each market lights as its vintage seals.

2 What it is not

Not a price. Not a terminal. Not a news feed. Not a restated dataset.

3 The tool

3.1

One call:

{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_as_of","arguments":{"issuer":"NASDAQ:MSFT","as_of":"2023-03-15"}}}

at https://mcp.getasof.ai/mcp .

3.2

Nothing is answered from memory. Identity fields answer on the read-date clock: a field is held only if the record had read it by the date asked; the disclosure lines are the sealed vintage — public filings dated on or before that date, each with its source and read date, each signed.

3.3

Paying for a read: every read is free unless the agent asks for the offer (header x402-pay: 1); the door then answers HTTP 402 with a signed offer and the same call carries the payment and the receipt — data-paygo.ai.

4 The edge

Point-in-time fundamentals exist as premium products elsewhere; replay exists on terminals. "As of a date" alone is not the edge. The edge is five things the record already has by construction, which no feed vendor built:

Others sell point-in-time data; Allooloo sells point-in-time proof.

5 The proof

5.1

Each get_as_of read is cleared and receipted: subject, jurisdiction, rule version, the stated time of the read, the hash of the signed answer, and the link to the previous receipt in the chain. The door signs the receipt; the producing node signs the content under the record key.

5.2

verify_receipt is public. Anyone holding the receipt and the answer can confirm the answer is the one that was served, unaltered.

5.3

A firm's own auditor key (issue_auditor_key) lets model-risk, internal audit or an external auditor list and verify every as-of read behind a model — the signed input list of a backtest, replayable to any date.

5.4

The quant's artefact is therefore not a CSV. It is a receipt chain: a signed, chained statement of every record the model read, as of when, and what it said. Model validation, MiFID II record-keeping and SR 11-7 style reviews want exactly this and have never been able to buy it.

6.1

Door: https://mcp.getasof.ai/mcp — the same router as https://mcp.getissuer.ai/mcp : same index, no second copy of the history; read-only, no authentication, no account. get_as_of is routed to the node of the issuer's listing; the node signs and receipts; the router forwards.

6.2

Agent Card (A2A): https://agent.getasof.ai/.well-known/agent-card.json .

6.3

Tools: get_as_of, with resolve_issuer · list_events_since · list_nodes on the same door. list_events_since stays where it is; get_as_of reads the same history.

6.4

Regional doors: every node door answers get_as_of for its own market (mcp.<market>-cm-kg.ai/mcp, <market>.eu-cm-kg.ai/mcp).

8 Data path

8.1

Store: the Replay store under Data Vintage — sealed market-years, 2021 forward. get_as_of is a read over it. No new store, no second copy of the history.

8.2

Index: the router holds an index only; the record is served by the owning node's regional door in its own jurisdiction. getasof.ai routes the same way.

8.3

Nightly: the OpsAgents re-slate the trading day; a sealed year is immutable thereafter. Receipts chain per writer.

8.4

Two clouds: Azure primary, AWS warm standby (Data Ark). The vintage and the receipt chain are both in the ark.

8.5

Markets light one by one as each vintage seals (us first, then the roster). The door answers not_sealed until then rather than guessing.
