Benchmark and expiry
WTI and Brent references are distinct products, and dated futures differ from continuous chart series. Specify the selected contract or roll rule, quotation currency and unit; a generic OIL symbol is only a broker alias.
Oil data needs a named benchmark and contract definition before an API can deliver an unambiguous price.

Expose expiry and source metadata to consumers that store history or value positions. Test roll transitions and missing-contract behavior, and keep adjusted historical chart values separate from raw dated-contract observations.
Bring the proposed instrument list, source documentation and consumer workflow to a technical discussion. The agreed integration specification defines coverage, fields, usage permissions and acceptance tests.
| Instrument scope | Identify the exact underlying, source identifier, quote currency and intended use. |
|---|---|
| Consumer workflow | List trading platforms, charts, risk tools and applications that need the output. |
| Delivery contract | Agree protocol, quote fields, timestamps, source status and recovery behaviour. |
| Production review | Confirm source rights, integration ownership, test evidence and commercial scope. |
For energy and commodities, define who consumes the prices and what each system needs to reconstruct a usable quote. An application dashboard, broker platform and historical process can require different delivery rules even when they share one normalized instrument model.
