--- name: blockscout-openapi-skill description: Operate Blockscout explorer reads through UXC with a curated OpenAPI schema, instance-specific host selection, and read-first guardrails. --- # Blockscout Explorer API Skill Use this skill to run Blockscout explorer 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 a Blockscout deployment that exposes `/api/v2`. - Access to the curated OpenAPI schema URL: - `https://raw.githubusercontent.com/holon-run/uxc/main/skills/blockscout-openapi-skill/references/blockscout-v2.openapi.json` - A target Blockscout instance. Examples in this skill use `https://eth.blockscout.com/api/v2`. ## Scope This skill covers a read-first explorer surface: - address summary lookup - address token balances - address transaction history - token metadata - token holder reads - transaction detail lookup - block detail lookup This skill does **not** cover: - Blockscout GraphQL - raw JSON-RPC proxying - write operations or admin/configuration flows - custom authenticated gateways beyond what the caller explicitly binds ## Authentication Public Blockscout instances usually allow explorer reads without auth. If you are targeting a self-hosted or gateway-protected instance, configure auth separately with standard `uxc auth` bindings for that host. This skill does not assume any default credential. ## Core Workflow 1. Use the fixed link command by default: - `command -v blockscout-openapi-cli` - If missing, create it: `uxc link blockscout-openapi-cli https://eth.blockscout.com/api/v2 --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/blockscout-openapi-skill/references/blockscout-v2.openapi.json` - `blockscout-openapi-cli -h` 2. Inspect operation schema first: - `blockscout-openapi-cli get:/addresses/{address_hash} -h` - `blockscout-openapi-cli get:/tokens/{address_hash} -h` - `blockscout-openapi-cli get:/transactions/{hash} -h` 3. Prefer narrow lookup validation before larger history reads: - `blockscout-openapi-cli get:/blocks/{block_number_or_hash} block_number_or_hash=latest` - `blockscout-openapi-cli get:/addresses/{address_hash} address_hash=0xd8da6bf26964af9d7eed9e03e53415d37aa96045` - `blockscout-openapi-cli get:/tokens/{address_hash} address_hash=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48` 4. Execute with key/value parameters: - `blockscout-openapi-cli get:/addresses/{address_hash}/transactions address_hash=0xd8da6bf26964af9d7eed9e03e53415d37aa96045` - `blockscout-openapi-cli get:/tokens/{address_hash}/holders address_hash=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48` ## Operation Groups ### Address Reads - `get:/addresses/{address_hash}` - `get:/addresses/{address_hash}/token-balances` - `get:/addresses/{address_hash}/transactions` ### Token, Transaction, And Block Reads - `get:/tokens/{address_hash}` - `get:/tokens/{address_hash}/holders` - `get:/transactions/{hash}` - `get:/blocks/{block_number_or_hash}` ## Multi-Instance Use To target a different Blockscout deployment, keep the same schema and relink the command to another host that serves `/api/v2`: ```bash uxc link blockscout-openapi-cli https://optimism.blockscout.com/api/v2 \ --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/blockscout-openapi-skill/references/blockscout-v2.openapi.json ``` ## 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 transaction broadcast or contract write support. - This schema is designed for Blockscout deployments that expose the explorer REST surface at `/api/v2`. If host help fails, check the deployment path before assuming a protocol mismatch. - Pagination and filter options vary across deployments. Start with host help and operation help on the target instance before building large crawls. - `blockscout-openapi-cli <operation> ...` is equivalent to `uxc <blockscout_api_v2_host> --schema-url <blockscout_openapi_schema> <operation> ...`. ## References - Usage patterns: `references/usage-patterns.md` - Curated OpenAPI schema: `references/blockscout-v2.openapi.json` - Blockscout API docs: https://docs.blockscout.com/devs/apis-redirect
