Pattern matching

Many Neuron API endpoints support pattern matching to help you filter and query data efficiently without fetching everything.

Query parameters

Use the filter query parameter with a pattern expression:

GET /v1/resources?filter=name:starts_with:acme

Operator	Description	Example
`eq`	Exact match	`status:eq:active`
`neq`	Not equal	`status:neq:archived`
`starts_with`	Prefix match	`name:starts_with:acme`
`contains`	Substring match	`description:contains:payment`
`gt` / `lt`	Greater / less than	`amount:gt:100`
`in`	Match any of a list	`type:in:invoice,receipt`

Chain multiple filters using &:

GET /v1/resources?filter=status:eq:active&filter=type:in:invoice,receipt

Use * as a wildcard in string patterns:

GET /v1/resources?filter=name:contains:acme*corp
