get_chain_status

Current state of the Doichain network as seen by the node behind this server: block height, sync state, time of the last block, fork check, node version, peers, mempool size and whether public anc…

hash_text

Compute the SHA-256 digest of a short text (UTF-8) on the server, for example to anchor a statement or a message with anchor_proof. The text is sent to the server but not stored or logged. For fil…

check_proof

Check whether a SHA-256 hash is anchored on the Doichain (name poe/<sha256>) and since when. Returns status (confirmed, pending, expired, unknown) and at the top level block height, block time, tr…

anchor_proof

Anchor a SHA-256 hash on the Doichain as a tamper-evident timestamp (proof of existence, name poe/<sha256>). Free for users, limited per IP address and day (see get_anchoring_quota). Confirms with…

get_anchoring_quota

How many proofs can still be anchored today (UTC day) within the free public quota for the caller's IP address. Hosted chat apps connect from their own servers, so their users share one quota. Cal…

lookup_name

Read the current value, owner address and expiry of a Doichain name. Unregistered names come back with exists false and status not_registered (the name is free). Expired names have status expired …

get_name_history

All registrations and updates of a name, newest first: block height, transaction, owner address and the value at that time. Shows who held a name when, and every value it ever had.

check_name_expiry

Check up to 25 names at once: status (active, expiring_soon, expired, not_registered), blocks left, an estimated expiry date for active names (from the measured block interval) and the real expiry…

search_names

List names that start with a prefix, in the node's order (shorter names first, then byte order). Lists only active names unless include_expired is true. Expired names (for example old poe/ proofs)…

get_block

Header data of a block by height or hash: time, confirmations, number of transactions and the first 50 transaction IDs.

get_transaction

A transaction with confirmations, block time, outputs (amount in DOI and address) and any name operation (name_doi, name_update, ...) it contains.

get_address

Confirmed and unconfirmed balance of a Doichain address in DOI, optionally with its most recent transactions. Invalid addresses return an error with the reason.

verify_message

Check whether a message was signed with the private key of a Doichain address (signmessage format). Only legacy addresses (M... or N...) can sign messages, bech32 addresses (dc1q...) are not suppo…
