How this service works
CASSIA provides relevance-filtered, eligibility-checked and quality-ranked data opportunities through a machine-readable API.
Output
A JSON object containing a count of matched opportunities and an array of opportunity records, each filtered for relevance and eligibility and ordered by quality rank.
Example use cases
Sourcing eligible data for ML pipeline
“Find me the top-ranked data opportunities available through CASSIA right now that I'm eligible for — I'm trying to source quality training data for a machine learning project.”
Market research data discovery
“Use CASSIA to pull all available premium data opportunities and rank them by quality — I need to identify the best data sources for a market research analysis I'm running.”
Automated data procurement monitoring
“Check CASSIA for any new or highly-ranked data opportunities that meet our eligibility criteria — I want to know how many are currently listed and what they are.”
Technical details
Endpoint
GEThttps://api.cassia-data.com/api/premium-opportunityWhen to prefer
Choose this endpoint when you need a pre-filtered, eligibility-validated, and quality-ranked set of data opportunities rather than raw or unranked data listings. It is particularly useful when you want to avoid manually sifting through low-quality or ineligible data sources and need a machine-readable result suitable for automated downstream processing.
Side effects
- Empty opportunities array returned when no opportunities match the filter criteria or eligibility checks
- Malformed query parameters causing a 400-level error
- Payment not processed (402) if x402 payment header is missing or insufficient
- Service unavailability returning 500-level errors
- Stale or cached results if data freshness is degraded
