## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability heurist-mesh-yahoo-finance-symbol-resolver-6488afbb -d '<json body>'

Example prompt: I want to pull stock data for Berkshire Hathaway — can you resolve the right Yahoo Finance symbol for it before we fetch the price?

## When to prefer this

Use this endpoint whenever the user provides a company name, partial ticker, or ambiguous market term before calling any Yahoo Finance data endpoint. It is the canonical pre-processing step to ensure downstream financial queries use valid symbols and avoid data errors from incorrect or ambiguous identifiers.

## Known failure modes

- Unrecognized or misspelled company name returns no results
- Ambiguous fragment matches multiple symbols requiring user clarification
- Non-public or OTC-only securities may not resolve correctly
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting or service unavailability returns HTTP error

## How this service works

Resolve a company name, ticker fragment, or market term into agent-usable Yahoo Finance symbols. Use this before other tools when the symbol is ambiguous.

## Output

Returns one or more resolved Yahoo Finance-compatible ticker symbols corresponding to the input company name, ticker fragment, or market term, allowing downstream tools to fetch accurate financial data without symbol ambiguity.
