# get_ticker — the issuer behind a ticker, with the receipt.

get_ticker · on the record

- 41887 issuers on the record (list_nodes)
- 34 markets live (list_nodes)
- 6 receipts written (get_ticker reads, receipted)

read at render: list_nodes at `https://mcp.getissuer.ai/mcp` and the gate's receipt counter

get_ticker is the issuer behind a ticker: a ticker and its exchange, or an ISIN or LEI, returns the issuer, its ISIN, its LEI, its listing and its status — every value with its source page and read date, signed by the node of the listing's market and receipted. Served from the record as read; a value the market's record does not carry says not_on_record.

## 1 What it answers

- **1.1** Input: identifier (ticker, ISIN or LEI) · exchange (optional, for a ticker) · market (optional).
- **1.2** Output: the issuer's name, ISIN, LEI and ticker; the listing (exchange, security type, segment); the status (listed; halted where the node's halt flag says so) — each with its source page and read date; the answer signed by the node and its RCO receipt.
- **1.3** A ticker that names more than one listing answers ambiguous with the candidates; name the exchange or give the ISIN.

## 2 Who it is for

Agents resolving a symbol before an order, a read or a citation: order routers, KYC and reference-data checks, research agents.

## 3 What it is not

Not a price. Not a quote. Not a reference-data licence. Not a symbol guess: a ticker the record does not hold answers unknown_issuer.

## 4 The tool

| typed error | when |
| --- | --- |
| unknown_issuer | no issuer on the register for this identifier |
| ambiguous | more than one listing matches; the candidates are named |
| not_on_record | the market's record does not carry this field; the market and the record's reason are named |
| invalid_request | a required argument is missing or not a date |

- **4.1** One call: 
```
{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_ticker","arguments":{"identifier":"AAPL","exchange":"NASDAQ"}}}
```
 at `https://mcp.getticker.ai/mcp` .
- **4.2** Every answer is signed by the node of the issuer's market (EdDSA, kid allooloo-cmr-2026-10, keyring [allooloo.ai/.well-known/jwks.json](https://allooloo.ai/.well-known/jwks.json)) and receipted at `https://mcp.rco-records.ai/mcp` with the node as writer; verify_receipt is public.
- **4.3** 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](https://data-paygo.ai/).
