Upland Appchain History & Chain API

Public, unauthenticated Antelope (Leap 5.0.3) node and Hyperion 3.3.10 full-history API for Upland's own appchain, which replaced Upland's EOS deployment on 2025-04-26. Exposes the standard Antelope /v1/chain RPC (get_info, get_account, get_table_rows, get_abi, push_transaction and friends) plus Hyperion V1 and V2 history, state and stats endpoints for indexed actions, deltas, transactions, token holders, account creators, proposals and resource usage. Documented by Upland on its own Upland Appchain developer page alongside the ledger.upland.me block explorer.

Where this information came from

This is an independent, third-party profile of Upland Appchain History & Chain API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
