The engine. Just the engine.
Three APIs: Scan & Grade, ATRIX doubt, and Rank forecast. For institutes and edtech builders who have their own app, their own students, their own brand — and want our math-verified grading or doubt tutor running behind their own UI.
Not self-serve. Pricing is per-institution, negotiated against volume and use case. The consumer subscription doesn’t include API access.
# Grade one scanned answer sheet.
# Returns step-level feedback in ~40s.

}Three surfaces. Priced per call.
Volume pricing past 100k calls/month. Rates negotiated in the partnership agreement — published prices are list.
The boring parts.
Rate limits
60 req/s per key, burstable to 300. Bulk grading is async — queue up to 10,000 pages and poll.
SLA
99.5% uptime, credited back past that threshold. P95 latency: grade 42s, atrix 3.1s, predict 180ms.
Data residency
AWS Mumbai. All student content retained 30 days then purged. Zero-retention mode available for regulated use cases.
Training
Your API payloads are never used to train our base models. This is in the contract and audited in SOC 2.
Whitelabel
The "Powered by AspireACE" line is required in the first cohort; removable at an enterprise tier.
Fourteen partners this year.
We’re deliberately small. API access is not a self-serve signup — every partner goes through a call with our solutions team first, because bad integrations reflect on our engine. Apply with a short note about what you’re building.
Typical response: 3 working days. Please include: your product, expected call volume, and which endpoint you care about first.
