Overview of a bloxberg network: chain id, latest block number, gas price, node client version, and public endpoints. Also lists all networks this server knows.

Fetch a block by number, hash, or "latest". Returns header fields and transaction hashes (or full transactions if requested).

Fetch a transaction and its receipt by hash. The receipt includes status, gas used, and logs.

Native token (BERG) balance of an address, in wei and formatted.

Call a read-only (view/pure) contract function. Pass the function as a human-readable ABI signature, e.g. "function balanceOf(address) view returns (uint256)" or "function name() view returns (string)". Arguments are passed as strings and coerced by type.

Transaction history of an address from the Blockscout explorer, newest first. Paginated.

Metadata for an ERC-20/721/1155 token contract (name, symbol, decimals, supply, type) from the Blockscout explorer.

Verified source code, compiler settings, and ABI of a contract from the Blockscout explorer (empty result if the contract is not verified).

Parse a bloxberg Research Object Certificate (W3C Verifiable Credential) WITHOUT verifying it: shows issuer, subject, dates, proof type, and anchoring hints. Purely local — no network calls. Use verify_certificate for cryptographic verification against the chain.

Cryptographically verify a bloxberg Research Object Certificate against the blockchain using the bloxberg cert-verifier engine (@bloxberg-org/cert-verifier-js-bloxberg): format validation, MerkleProof2019 replay, on-chain Merkle root comparison, issuer identity, and status checks. Returns the final verdict plus every verification step. Note: a bare file hash cannot be verified — bloxberg anchors only Merkle batch roots on-chain, so the full credential document is required.
