--- name: mexc-openapi-skill description: Operate MEXC Spot REST APIs through UXC with a curated OpenAPI schema, HMAC query signing, and separate public/signed workflow guardrails. --- # MEXC Spot API Skill Use this skill to run MEXC Spot REST 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.mexc.com`. - Access to the curated OpenAPI schema URL: - `https://raw.githubusercontent.com/holon-run/uxc/main/skills/mexc-openapi-skill/references/mexc-spot.openapi.json` ## Scope This skill covers a curated MEXC Spot REST surface for: - public market reads - signed account reads - signed order create, cancel, and lookup flows This skill does **not** cover: - futures APIs - broader platform product families ## Authentication Public market endpoints do not require credentials. Signed Spot endpoints require: - `api_key` field for `X-MEXC-APIKEY` - `secret_key` field for HMAC SHA256 query signing Create one credential: ```bash uxc auth credential set mexc-spot \ --auth-type api_key \ --field [REDACTED_SECRET] \ --field secret_key=env:MEXC_SECRET_KEY ``` Add one signer binding: ```bash uxc auth binding add \ --id mexc-spot \ --host api.mexc.com \ --path-prefix /api/v3 \ --scheme https \ --credential mexc-spot \ --signer-json '{"kind":"hmac_query_v1","algorithm":"hmac_sha256","signing_field":"secret_key","key_field":"api_key","key_placement":"header","key_name":"X-MEXC-APIKEY","signature_param":"signature","signature_encoding":"hex","timestamp_param":"timestamp","timestamp_unit":"milliseconds","canonicalization":{"mode":"preserve_order"}}' \ --priority 100 ``` Validate the active mapping when auth looks wrong: ```bash uxc auth binding match https://api.mexc.com/api/v3/account ``` ## Core Workflow 1. Use the fixed link command by default: - `command -v mexc-openapi-cli` - If missing, create it: `uxc link mexc-openapi-cli https://api.mexc.com --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/mexc-openapi-skill/references/mexc-spot.openapi.json` - `mexc-openapi-cli -h` 2. Inspect operation help before execution: - `mexc-openapi-cli get:/api/v3/ticker/price -h` - `mexc-openapi-cli get:/api/v3/account -h` - `mexc-openapi-cli post:/api/v3/order -h` 3. Prefer public reads first: - `mexc-openapi-cli get:/api/v3/ticker/price symbol=BTCUSDT` - `mexc-openapi-cli get:/api/v3/depth symbol=BTCUSDT limit=20` 4. Use signed reads before writes: - `mexc-openapi-cli get:/api/v3/account recvWindow=5000` - `mexc-openapi-cli get:/api/v3/openOrders symbol=BTCUSDT recvWindow=5000` ## Operation Groups ### Public Market - `get:/api/v3/ping` - `get:/api/v3/exchangeInfo` - `get:/api/v3/ticker/price` - `get:/api/v3/ticker/24hr` - `get:/api/v3/depth` ### Signed Reads - `get:/api/v3/account` - `get:/api/v3/openOrders` - `get:/api/v3/order` ### Signed Writes - `post:/api/v3/order` - `delete:/api/v3/order` ## Guardrails - Keep automation on the JSON output envelope; do not use `--text`. - Parse stable fields first: `ok`, `kind`, `protocol`, `data`, `error`. - Treat signed write operations as high-risk and require explicit confirmation before execution. - `timestamp` and `signature` are injected by the signer binding; users normally provide business parameters plus optional `recvWindow`. - Query `exchangeInfo` before placing orders so symbol filters and lot sizes are known. - `mexc-openapi-cli <operation> ...` is equivalent to `uxc https://api.mexc.com --schema-url <mexc_spot_openapi_schema> <operation> ...`. ## References - Usage patterns: `references/usage-patterns.md` - Curated OpenAPI schema: `references/mexc-spot.openapi.json` - Official MEXC Spot v3 docs: https://mexcdevelop.github.io/apidocs/spot_v3_en/
