Kaspa fee-market regime: fee-bucket distribution incl. the sub-floor segment the Toccata minimum displaces. Informational research data — not investment advice.

Hourly emission and stake trend for a Bittensor subnet (window: 1h/24h/7d/30d). Derived from bittensor_metagraph snapshots. AI agent API for subnet-momentum tracking. Informational research data — not investment advice.

Bittensor NeuronRegistered count per hour. Tracks new neurons joining subnets — useful for detecting subnet growth/decay and registration-burn pressure. AI agent API for subnet-health analysts. Informational research data — not investment advice.

Filtered Bittensor substrate event stream from finalized blocks. Module/event filters supported. Read from the public Bittensor (Finney) RPC and archived, so events stay queryable after public lite nodes prune them.

Single Kaspa block extract with full DAG topology (parents, selected-parent, blue/daa score, chain-block flag). AI agent API for DAG-aware indexers. Informational research data — not investment advice.

Recent Kaspa blocks (max 144 blocks per call, flat price per call). Optional chain_only flag to filter selected-parent chain blocks. AI agent API for backtesters and indexers. Informational research data — not investment advice.

Historical Kaspa network metrics as server-side aggregated timeseries (max 1000 points): hashrate, difficulty, DAG block rate, mempool depth, DAA score, tip count, circulating supply, percent mined; peer count only until 2026-08-10. Collected continuously by our own infrastructure (own Kaspa node until 2026-08-10, since then snapshots of the public api.kaspa.org). Informational research data — not investment advice.

Bitcoin own-node peer-network diversity (IPv4/IPv6/Tor/I2P/CJDNS distribution) + privacy share. AI agent API for privacy researchers, node-operator tooling, network-health analytics. Informational research data — not investment advice.

Kaspa network hashrate (H/s) + difficulty trend from 5-minute snapshots of the public Kaspa node REST observer (api.kaspa.org). Post-fork mining-security telemetry. Informational research data — not investment advice.

Kaspa BlockDAG topology snapshot: tips, sink, virtual chain, pruning point, blue scores. For DAG-state monitoring, side-branch detection, sync verification.

Recent per-block aggregation of Bittensor events: neuron_registrations, weight_sets, bond_sets, child_key_sets, stake_added/removed, root_claimed, balance_transfers + total TAO.

Latest alpha-token price per Bittensor subnet (TAO + USD). All 129 subnets in one call. AI agent API for cross-subnet price arbitrage, dTAO portfolio rebalancing. Informational research data — not investment advice.
