Market data interface list for the product team: first ensure traceability, then pursue richness

The Primary Responsibility of Interface Fields is to Reduce Ambiguity

Market data interfaces do not just return prices or trading volumes. For tokenized assets, the product team should first ensure that each result can be pinpointed to the asset version, issuer or contract identifier, trading venue, quote currency, price type, and timestamp. When fields are incomplete, subsequent charts and calculations will amplify ambiguity.

Provide Definitions for Each Metric

"Trading volume," "market share," "depth," or "open interest" may have different calculation scopes in different markets. The API documentation should specify the observation window for the metrics, aggregation methods, included or excluded entities, and when to return null or missing values. This way, users can understand what the results are suitable for describing.

Retain Source and Version Information

Data governance needs to answer: Where does this data come from, when was it fetched, has it been aggregated, and has the product information been revised? Providing source, update time, and method links along with the main fields helps the product team handle disputes, correct errors, and respond to customer inquiries.

Do Not Wrap Interface Outputs as Conclusions

Interfaces can provide verifiable observations, but data labels should not be designed as judgments like "best," "safe," or "about to rise." The credibility of data products comes from transparency and traceability, not from drawing conclusions for users.
