The AgentCrush Dataset

Daily snapshots of 1,400+ AI agents tracked across the ecosystem. Liveness-scored, methodology-versioned, and anchored on-chain every night. All endpoints are free and open — no account required for research use.

What the dataset is

Coverage1,428 agents indexed

GitHub, Virtuals, Agentverse, ERC-8004, and direct submissions — cross-protocol.

Evidence-ranked179 agents

Multi-signal corroboration: stars, citations, deployments, protocol presence, on-chain registrations.

Daily snapshots100,000+ rows total

Daily scoring run since April 2026. Liveness, tier, signal breakdown per agent per day.

On-chain anchorsNightly on Base

SHA-256 Merkle root of the daily snapshot committed to Base (public tx). Methodology-versioned.

Ghost Index55% liveness (785 alive)

Daily liveness index published free. History included in the API response.

How to access it

All endpoints are CORS-open, no API key required for the free tier. Paid endpoints ($0.05) accept x402 payment or a Pro key. Full OpenAPI spec at /api/openapi.json.

Provenance and auditability

Every ranking score is produced by a published Postgres view. The nightly snapshot commits a SHA-256 Merkle root of all daily scores to a public Base transaction — the on-chain hash is the receipts layer for any later audit.

Methodology is versioned and stable enough to cite. If scoring rules change, a new version string is issued — old attestations remain interpretable against the version that produced them.
