chainbase-openapi-skill（chainbase openapi 技能）

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

Core Workflow

1. Use the fixed link command by default:

- command -v chainbase-openapi-cli - If missing, create it: uxc link chainbase-openapi-cli https://api.chainbase.online --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/chainbase-openapi-skill/references/chainbase-web3.openapi.json - chainbase-openapi-cli -h

1. Inspect operation schema first:

- chainbase-openapi-cli get:/v1/account/balance -h - chainbase-openapi-cli get:/v1/account/tokens -h - chainbase-openapi-cli get:/v1/token/metadata -h

1. Prefer narrow account validation before broader reads:

- chainbase-openapi-cli get:/v1/account/balance chain_id=1 address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 - chainbase-openapi-cli get:/v1/token/price chain_id=1 contract_address=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 - chainbase-openapi-cli get:/v1/tx/detail chain_id=1 tx_hash=0x4e3f3bc239f496f59c3e4d4a4d5f10f7f0d6d9f4cd790beeb520d05f6f7d98ae

1. Execute with key/value parameters:

- chainbase-openapi-cli get:/v1/account/tokens chain_id=1 address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 page=1 limit=20 - chainbase-openapi-cli get:/v1/token/holders chain_id=1 contract_address=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 page=1 limit=20

Operation Groups

Account Reads

• get:/v1/account/balance
• get:/v1/account/tokens
• get:/v1/account/txs

Token And Transaction Reads

• get:/v1/token/metadata
• get:/v1/token/holders
• get:/v1/token/price
• get:/v1/tx/detail

Guardrails

• Keep automation on the JSON output envelope; do not use --text.
• Parse stable fields first: ok, kind, protocol, data, error.
• Treat this v1 skill as read-only. Do not imply RPC write methods, mempool send, or signing support.
• Chainbase has multiple product surfaces. This skill is intentionally limited to indexed HTTP reads on https://api.chainbase.online.
• Start with small page and limit values before building large crawls.
• chainbase-openapi-cli <operation> ... is equivalent to uxc https://api.chainbase.online --schema-url <chainbase_openapi_schema> <operation> ....
