Capabilities
A supply intelligence layer, not a utility
The Alargo API exposes a continuously maintained supply graph and intelligence services that teams can plug into dashboards, pipelines, and internal tooling.
Verification
Authorization & supply quality
Validate seller authorization, classify supply roles, and surface high-risk paths before spend flows.
Monitoring
Drift detection & alerts
Detect supply drift and changes that impact eligibility, cost, or governance during a campaign window.
Scoring
Path scoring & recommendations
Turn graph outputs into decisions: score paths, rank routes, and generate enforceable supply rules.
We intentionally describe capabilities at a high level. Implementation details and deeper metrics are available in enterprise evaluations and partner documentation.
Endpoints
Representative endpoints
RESTful JSON API with straightforward authentication. Examples below are illustrative and may vary by plan or integration.
/v1/supply-paths/{domain}
Returns normalized supply paths for a domain, including relationship classification, authorization signals, and path quality scoring.
{
"domain": "example.com",
"summary": {
"publisher_coverage": "indexed",
"path_quality_score": 87
},
"paths": [
{
"provider": "google",
"relationship": "DIRECT",
"authorized": true,
"path_score": 92
}
// ... additional paths
]
}
/v1/supply-rules/generate
Generate enforcement-ready supply rules from domains, apps, or inventory lists. Returns DSP-ready exports and a full audit trail of why items were included or excluded.
// Request
{
"targets": [
{"type": "domain", "value": "nytimes.com"},
{"type": "domain", "value": "wsj.com"}
],
"policy": {
"exclude_resellers": true,
"min_path_score": 80
},
"export": "dv360"
}
/v1/monitoring/drift
Returns classified drift events across monitored inventory since a timestamp. Designed for in-flight governance and automated workflows.
{
"since": "2025-01-15T08:30:00Z",
"events": [
{
"domain": "example.com",
"category": "authorization_drift",
"severity": "high",
"detected_at": "2025-01-15T08:41:12Z"
}
]
}
/v1/authorization/check
Validate whether a specific seller is authorized for a domain on a given provider. Useful for QA checks, audits, and internal tooling.
// GET /v1/authorization/check?domain=example.com&provider=openx&seller_id=12345
{
"domain": "example.com",
"provider": "openx",
"seller_id": "12345",
"authorized": false,
"reason": "not_authorized"
}
Integration
Integration patterns
How teams wire Alargo into decisioning, governance, and media operations.
Automated QA
Add authorization checks to internal QA pipelines. Flag risk before spend and create audit trails for governance.
Supply rules at scale
Generate enforceable rules and DSP-ready exports from lists, plans, or inventory sets. Standardize policy across teams.
Drift & enforcement loops
Detect drift and trigger actions: notify owners, refresh rules, re-export lists, or open internal tickets.
Technical
Operational details
Authentication & tenancy
Bearer tokens with organization scoping and key rotation. Optional IP allowlisting and scoped permissions by integration.
Reliability
Designed for production workflows with stable schemas, versioned endpoints, and predictable error semantics.
Data freshness
Signals are refreshed continuously with drift classification designed for near real-time workflows. Freshness SLAs are available in enterprise plans.
Security
TLS everywhere. Enterprise options include SSO, audit logging, and dedicated environments for regulated workflows.
Need deeper technical documentation? We provide full API specs and integration guides after approval for API access.
Make supply intelligence
a service.
If you are building internal tooling or scaling SPO, the fastest path is to call the Alargo API rather than maintain your own supply graph.
