API Access

API Access

Go-to-market systems are crippled by duplicate, stale, and siloed company and contact records that steal hours and undermine revenue execution. Creso.ai’s API Access exposes a secure, versioned REST surface to the Creso knowledge graph so you can programmatically search, retrieve, and update deduped, enriched, and always-current company and person records — with match confidence, provenance, and auditability built in.

  • check Single source of truth across systems

    Connect any CRM, marketing tool, or internal app to one canonical dataset (Creso IDs) and stop reconciling multiple enrichment feeds, duplicate records, and conflicting identifiers.

  • check Real-time freshness with predictable performance

    Just-in-time enrichment and a smart caching policy return fresh, high-confidence entities on-demand (sync or async), eliminating brittle cron jobs and manual re-syncs while providing clear latency and rate-limit behavior.

  • check Developer-first controls and governance

    Versioned endpoints, scoped API key and detailed provenance let engineering and RevOps safely automate enrichment, enforce golden records, and meet audit/compliance needs.

Creso.ai’s API Access is the programmatic gateway to the platform’s dynamic knowledge graph: a unified repository of 250M+ companies and 1.2B people that hides the complexity of multiple enrichment vendors, deduplication logic, and entity resolution. Developers call a small set of predictable REST endpoints (search by domain/email, fetch by Creso ID) and receive a consistent JSON profile that and field-level provenance so every consumer can trust the data they act on.

Under the hood the API runs a hybrid model: cached canonical entities backed by just-in-time pulls from trusted providers when data is stale or missing. Calls refresh inline within a time budget and return the canonical entity; if refresh exceeds the budget an optional signed webhook when the update completes. This gives teams a predictable trade-off between freshness and latency while surfacing clear reasons and scores for why a match was made.

The API also supports customer overlays so teams can persist CRM-specific attributes (owner, tier, lifecycle stage) that flatten into the presented entity while being stored and auditable separately. Overlays are idempotent, respect merge precedence and include actor/timestamp diffs for governance — enabling RevOps and Product teams to enforce golden records without losing the benefits of a shared enrichment fabric.

How It Works

1

Authentication & Security

Bearer API keys over secure connection and auditable access logs ensure secure, compliant integration.

2

Identity Resolution & Canonicalization

Deterministic and probabilistic matching (domain, email, token similarity, HQ proximity, corporate tree) resolves queries to stable Creso IDs with an explicit match_score and reason list so integrations can confidently upsert or dedupe.

3

Just-in-Time Enrichment & Caching

Smart cache policies (companies stale after 30 days, people after 14) trigger on-demand pulls from underlying providers; mode=sync attempts inline refresh within a short time budget while mode=async returns a job_id and optional webhook for completion.

4

Overlays, Concurrency & Auditability

Customer overlays let you write CRM-specific fields that take precedence and can be locked and overlay changes are logged with actor/timestamp diffs for compliance and rollback.
