Glossary

One definition per term. If a page uses a name you don’t recognize, it’s here — in alphabetical order, each linking back to the page where it’s actually used.

as_of

A timestamp on every agent data plane read stating when the underlying data was actually observed, so a response never silently claims fresher data than it has.

See it in context: /features/agent-data-plane/

Credit

The spend unit charged for enrichment actions such as fetching people, emails and phone numbers; read-only actions like CSV exports never spend credits.

See it in context: /features/compare-people-data-providers/

Filter

A rule that narrows which signals or companies a search returns, applied either at the source or after signals are fetched.

See it in context: /features/advanced-search/

Persona

A saved set of job titles and location criteria used to find and prioritize decision-makers at a matched company.

See it in context: /features/find-decision-makers/

Project

The object the REST API and this documentation call a Project is the same saved set of qualified leads the app interface calls a Lead List.

See it in context: /features/api-access/

Also called: Lead List.

Provenance envelope

The wrapper around each headline value on the agent data plane’s four history-backed reads, naming the source board, observation time and a confidence score.

See it in context: /features/agent-data-plane/

Search

A saved set of keyword, semantic and filter criteria that SignalsAPI runs continuously to find new matching signals.

See it in context: /features/advanced-search/

Signal

An observed activity or change at a company — most often a new job posting — that indicates potential buying interest and gets evaluated against your ICP.

See it in context: /faq/

Tier 0

The agent data plane’s cached-read tier, billed one call unit each and floored on data freshness rather than rate-limited by call volume.

See it in context: /features/agent-data-plane/

Tier 1

The agent data plane’s freshness-aware read tier, where a declared max_age is honestly met or reported unmet rather than silently ignored.
