| "Q42" is a valid Wikidata ID, and a Wikidata items exists with that Id, so it is therefore returned intact

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|Q0|'''nil'''}}</code>

| "Q0" is not a valid Wikidata ID, and while the Wikipedia article [[Q0]] exists, it is a disambiguation page, so <code>'''nil'''</code> is returned

|<syntaxhighlight lang="lua">local resolveEntityresolveEntityId = require( "Module:ResolveEntityId" )._id

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|Q404|'''nil'''}}</code>

| "Q404" is a Wikidata redirect to Q395, so the latter is returned

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|Q151384451555Q2147483647|'''nil'''}}</code>

| Q2147483647 is a valid Wikidata ID, but no entity exists with that ID, so <code>'''nil'''</code> is returned

|-

|<syntaxhighlight lang="lua">local resolveEntityresolveEntityId = require( "Module:ResolveEntityId" )._id

id = resolveEntity._idresolveEntityId('Douglas Adams')</syntaxhighlight>

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|Douglas Adams|'''nil'''}}</code>

| The article [[Douglas Adams]] exists and has the Wikidata ID "Q42", so that is returned.

|<syntaxhighlight lang="lua">local resolveEntityresolveEntityId = require( "Module:ResolveEntityId" )._id

id = resolveEntity._idresolveEntityId('ThisIsNotARealWikidataItem')</syntaxhighlight>

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|ThisIsNotARealWikidataItem|'''nil'''}}</code>

| "ThisIsNotARealWikidataItem" is not a valid Wikidata ID, and no Wikipedia article exists at [[ThisIsNotARealWikidataItem]], so <code>'''nil'''</code> is returned

|-

|<syntaxhighlight lang="lua">local resolveEntityresolveEntityId = require( "Module:ResolveEntityId" )._id

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|ThisIsNotARealWikidataItem|'Wikidata ID not found!'}}</code>

| Same as above, but the custom error message <code>Wikidata ID not found!</code> is returned

|<syntaxhighlight lang="lua">local resolveEntityresolveEntityId = require( "Module:ResolveEntityId" )._id

id = resolveEntity._idresolveEntityId('WP:RDouglas adams')</syntaxhighlight>

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|WP:RDouglas adams|'''nil'''}}</code>

| "Douglas adams" is not a valid Wikidata ID, and while [[Douglas adams]] (with a lower-case "a") exists, it is a redirect to [[Douglas Adams]]. Therefore the Wikidata ID for the latter page is returned

|-

|<syntaxhighlight lang="lua">local resolveEntityId = require( "Module:ResolveEntityId" )._id

id = resolveEntityId('Wikipedia:Village pump (technical)/Archive 1')</syntaxhighlight>

|style="vertical-align: mid;"|<code>id</code> = <code>{{#invoke:ResolveEntityId|entityid|Wikipedia:Village pump (technical)/Archive 1|'''nil'''}}</code>

| "Wikipedia:Village pump (technical)/Archive 1" is not a valid Wikidata ID, and while [[Wikipedia:Village pump (technical)/Archive 1]] exists, it does not have a Wikidata ID, so <code>'''nil'''</code> is returned

=== Use from within a template (entityid) ===

The following will return the entity id (or <code>'''nil'''</code>nothing if the ID doesn't exist):

<code><nowiki>{{</nowiki>#invoke:{{BASEPAGENAME}}|entityid|''id''}}</code>
