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) 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.
