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

2. 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

3. 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

4. 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 ... is equivalent to uxc https://api.chainbase.online --schema-url ....
