--- name: alchemy-openapi-skill description: Operate Alchemy Prices API reads through UXC with a curated OpenAPI schema, path-templated API-key auth, and read-first guardrails. --- # Alchemy Prices API Skill Use this skill to run Alchemy Prices API 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.g.alchemy.com`. - Access to the curated OpenAPI schema URL: - `https://raw.githubusercontent.com/holon-run/uxc/main/skills/alchemy-openapi-skill/references/alchemy-prices.openapi.json` - An Alchemy API key. ## Scope This v1 skill intentionally covers the narrow Prices API surface: - token price lookup by symbol - token price lookup by contract address - historical token prices This skill does **not** cover: - node JSON-RPC - NFT or portfolio APIs - write operations - the broader Alchemy API surface - multi-symbol batch lookup in one `uxc` call ## Authentication Alchemy Prices API places the API key in the request path: `/prices/v1/{apiKey}/...`. Configure one API-key credential with a request path prefix template: ```bash uxc auth credential set alchemy-prices \ --auth-type api_key \ --secret-env ALCHEMY_API_KEY \ --path-prefix-template "/prices/v1/{{secret}}" uxc auth binding add \ --id alchemy-prices \ --host api.g.alchemy.com \ --scheme https \ --credential alchemy-prices \ --priority 100 ``` Validate the active mapping when auth looks wrong: ```bash uxc auth binding match https://api.g.alchemy.com ``` ## Core Workflow 1. Use the fixed link command by default: - `command -v alchemy-openapi-cli` - If missing, create it: `uxc link alchemy-openapi-cli https://api.g.alchemy.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/alchemy-openapi-skill/references/alchemy-prices.openapi.json` - `alchemy-openapi-cli -h` 2. Inspect operation schema first: - `alchemy-openapi-cli get:/tokens/by-symbol -h` - `alchemy-openapi-cli post:/tokens/by-address -h` - `alchemy-openapi-cli post:/tokens/historical -h` 3. Start with narrow single-asset reads before batch historical requests: - `alchemy-openapi-cli get:/tokens/by-symbol symbols=ETH currency=USD` - `alchemy-openapi-cli post:/tokens/by-address '{"addresses":[{"network":"eth-mainnet","address":[REDACTED_SECRET]}],"currency":"USD"}'` 4. Use positional JSON only for the POST endpoints: - `alchemy-openapi-cli post:/tokens/historical '{"symbol":"ETH","startTime":"2025-01-01T00:00:00Z","endTime":"2025-01-07T00:00:00Z","interval":"1d","currency":"USD"}'` ## Operations - `get:/tokens/by-symbol` - `post:/tokens/by-address` - `post:/tokens/historical` ## 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 and prices-only. Do not imply RPC, trade execution, or wallet mutation support. - API keys are sensitive because they appear in the request path. Use `--secret-env` or `--secret-op`, not shell history literals, when possible. - `/tokens/by-symbol` is query-based in the live API. - The live API supports repeated `symbols=` parameters, but this v1 skill intentionally narrows that endpoint to a single `symbols=<TOKEN>` query because current `uxc` query argument handling does not reliably execute array-shaped query parameters. - Historical requests can expand quickly. Keep time windows tight unless the user explicitly wants a larger backfill. - `alchemy-openapi-cli <operation> ...` is equivalent to `uxc https://api.g.alchemy.com --schema-url <alchemy_openapi_schema> <operation> ...`. ## References - Usage patterns: `references/usage-patterns.md` - Curated OpenAPI schema: `references/alchemy-prices.openapi.json` - Alchemy Prices API docs: https://www.alchemy.com/docs/reference/prices-api - Prices API endpoints: https://www.alchemy.com/docs/reference/prices-api-endpoints
