List agents

List all agents in the registry. Optionally enrich with health checks, capabilities, and property summaries via query parameters. Measurement-vendor filters (metric_id, accreditation, q) imply type=measurement when type is unset; an explicit type other than measurement returns 400.

Query Parameters

type · enum<string>

Available options: brand, rights, measurement, governance, creative, sales, buying, signals, unknown

health · enum<string>

Available options: true

capabilities · enum<string>

Available options: true

properties · enum<string>

Available options: true

compliance · enum<string>

Available options: true

metric_id · string string[]

Measurement-vendor filter: exact match on measurement.metrics[].metric_id. Repeatable (each value is OR'd within the param, AND'd with other filters). Implies type=measurement.

Example:

"attention_units"

accreditation · string string[]

Measurement-vendor filter: exact match on measurement.metrics[].accreditations[].accrediting_body (e.g. MRC, JIC, ARF). Repeatable. Implies type=measurement. Accreditation claims are vendor-asserted; AAO does not independently verify (verified_by_aao is always false in the response).

Example:

"MRC"

q · string

Measurement-vendor filter: case-insensitive substring match against measurement.metrics[].metric_id. v1 scope: metric_id only (description/standard search is a follow-up). Max 64 chars; SQL wildcard characters are escaped. Implies type=measurement.

Maximum string length: 64

Example:

"attention"

verification_mode · enum<string>[]

Filter to agents whose active badge covers the given verification axis. Repeat the parameter for AND semantics: ?verification_mode=spec&verification_mode=live returns only agents verified on both axes.

Available options: spec, live

verified · enum<string>

When true, filter to agents that hold any active verification badge.

Available options: true
