coinank-openapi

Overview

CoinAnk OpenAPI provides access to cryptocurrency derivatives market data, including K-lines, ETFs, open interest, long/short ratios, funding rates, liquidations, order flow, whale activity, and related analytics. Use direct API-key authentication when available, or use Agent Payments Protocol / x402 pay-per-call access through the latest OKX payment skill when CoinAnk returns a payment challenge.

Pre-flight Checks

Before using this skill, ensure:

1. Review the user's requested market-data task and select the matching reference OpenAPI file under references/ when endpoint details are needed.
2. If COINANK_API_KEY is available, use API-key mode and send it only in the apikey request header.
3. If no API key is available, send the original request first and only start Agent Payments Protocol / x402 payment handling after a real HTTP 402 Payment Required challenge or an OKX payment-skill charge requirement.
4. For paid challenges, use okx-agent-payments-protocol; do not implement wallet signing manually in this skill.
5. Confirm any payment with amount greater than zero with the user before payment execution. Zero-amount challenges are valid and must remain exactly zero.

Commands

This is a skill-only plugin. The command names below describe agent workflows, not a shipped local binary.
