# Neutron On-Chain API > Live on-chain data for Neutron (the Cosmos integrated DeFi L1, chain neutron-1) with no key: staking economics (bonded vs unbonded NTRN, bonded ratio, staking parameters), the active validator set (moniker, voting power, commission, status), the total NTRN supply, the on-chain community pool (treasury) holdings, and the latest block. ## Authentication All requests require your oanor API key in the `x-oanor-key` header. Get one at https://www.oanor.com/developer/keys. ```bash curl -H "x-oanor-key: oanor_live_…" "https://api.oanor.com/neutron-api/..." ``` ## Pricing - **Free** (Free) — 11,200 calls/Mo, 2 req/s - **Basic** ($20/Mo) — 251,000 calls/Mo, 10 req/s - **Pro** ($54/Mo) — 1,370,000 calls/Mo, 20 req/s - **Scale** ($125/Mo) — 7,280,000 calls/Mo, 50 req/s ## Endpoints ### Staking #### `GET /v1/staking` — Staking economics & parameters **Example:** ```bash curl -H "x-oanor-key: $KEY" \ "https://api.oanor.com/neutron-api/v1/staking" ``` **Response:** ```json { "data": { "note": "The Neutron staking economics — bonded vs unbonded NTRN, the bonded ratio, and the chain's staking parameters (unbonding period, max validators, minimum commission).
