Chainbase Web3 API Skill

Use this skill to run Chainbase indexed data operations through uxc + OpenAPI.

Reuse the uxc skill for shared execution, auth, and error-handling guidance.

Prerequisites

• uxc is installed and available in PATH.
• Network access to https://api.chainbase.online.
• Access to the curated OpenAPI schema URL:
  • https://raw.githubusercontent.com/holon-run/uxc/main/skills/chainbase-openapi-skill/references/chainbase-web3.openapi.json
• A Chainbase API key.

Scope

This skill covers a read-first indexed data surface:

• account native balance lookup
• account token balances
• account transaction history
• token metadata
• token holder reads
• token price lookup
• transaction detail lookup

This skill does not cover:

• raw chain RPC methods
• write or transaction submission flows
• the broader Chainbase data product surface beyond the selected Web3 API reads

Authentication

Chainbase uses X-API-KEY header auth.

Configure one API-key credential and bind it to api.chainbase.online:

uxc auth credential set chainbase \
  --auth-type api_key \
  --api-key-header X-API-KEY \
  --secret-env CHAINBASE_API_KEY

uxc auth binding add \
  --id chainbase \
  --host api.chainbase.online \
  --scheme https \
  --credential chainbase \
  --priority 100

Validate the active mapping when auth looks wrong:

uxc auth binding match https://api.chainbase.online
