Provenance Blockchain RWA Markers API

healthy 3,115 Subscribers

Live on-chain data from Provenance (pio-mainnet-1), the Cosmos-SDK layer-1 built by Figure for real-world-asset finance. Read the marker module — Provenance's tokenized-asset primitive: the registry of on-chain markers (tokenized assets and restricted security tokens) with each marker's denom, status, type (COIN vs RESTRICTED), on-chain supply and transfer/governance flags; the full detail of any marker including its access-control grants and required holder attributes; the address-level holders of a marker; plus the staking pool with bonded ratio and validator set, the total HASH supply and the latest block. The Provenance / RWA / tokenized-securities layer for explorers, asset dashboards and compliance tooling.

Numbers Protocol Chain API — oanor API marketplace

Numbers Protocol Chain API

Live on-chain data for the Numbers Protocol mainnet (Num Network, the EVM Layer-1 for media provenance and digital-content authenticity, native NUM) via Blockscout — no key. Read network stats (block height, total transactions, gas), a gas oracle in gwei, the most recent blocks and full block detail by height or hash, any address balance and contract info, full transaction detail, ERC-20 token detail by contract, and a universal search across addresses, tokens, blocks and transactions. Real Layer-1 chain data with the rotating proxy as automatic fallback — 9 endpoints. Ideal for wallets, explorers, provenance/asset tooling, portfolio trackers and on-chain monitoring on Numbers.

 MANTRA Chain On-Chain API — oanor API marketplace

MANTRA Chain On-Chain API

Live on-chain data for MANTRA Chain (the real-world-asset (RWA) tokenization L1, chain mantra-1) with no key: staking economics (bonded vs unbonded OM, bonded ratio, staking parameters), the active validator set (moniker, voting power, commission, status), the total OM supply, monetary inflation (annual rate, annual provisions, mint parameters), the latest governance proposals, and the latest block.

 Unit Zero Chain API — oanor API marketplace

Unit Zero Chain API

Live on-chain data for Unit Zero — an EVM Layer 1 for real-world assets and AI compute — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, validator and timestamp. The address endpoint returns any account's UNIT0 balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in UNIT0, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in UNIT0, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).
