--- name: chainbase-openapi-skill description: Operate Chainbase indexed wallet and token reads through UXC with a curated OpenAPI schema, API-key auth, and read-first guardrails. --- # 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`: ```bash 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: ```bash 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 <operation> ...` is equivalent to `uxc https://api.chainbase.online --schema-url <chainbase_openapi_schema> <operation> ...`. ## References - Usage patterns: `references/usage-patterns.md` - Curated OpenAPI schema: `references/chainbase-web3.openapi.json` - Chainbase auth docs: https://docs.chainbase.com/quickstart/authenticate-your-api-key - Chainbase Web3 API docs: https://docs.chainbase.com/api-reference/web3-api/balance
