What it does

The `/alpha/news` endpoint on the x402 Meta Gateway returns AI-filtered crypto news aggregated from CoinTelegraph, Decrypt, CoinDesk, and Blockworks, enriched with X/Twitter sentiment data. Each call costs $0.02 in USDC, payable on Base (EIP-155:8453) or Solana. The endpoint accepts optional `query` and `category` query parameters to filter by topic or news source respectively.

This endpoint is part of a broader 14-tool crypto intelligence gateway that covers token analysis, trending tokens, sentiment, search, deep research, prediction markets, macro economics, on-chain activity, token comparison, narrative tracking, event calendars, risk assessment, and portfolio analysis. All endpoints follow the x402 payment protocol (HTTP 402 challenge with USDC settlement) and return structured JSON with metadata envelopes including request IDs, confidence scores, source attribution, and timestamps.

The gateway aggregates data from CoinGecko, DexScreener, Alchemy, Helius, Grok AI, Exa, Firecrawl, Claude, Polymarket, Kalshi, FRED, and X/Twitter. A full OpenAPI 3.1.0 spec is served, and an MCP (Model Context Protocol) JSON-RPC endpoint is also available at `/mcp` for native AI agent integration. Prices across the gateway range from $0.02 to $0.10 per call depending on the endpoint.

Quality

Full OpenAPI 3.1.0 schema is available with clear parameter definitions, the x402 challenge is live and well-formed with pricing on two chains, and the landing page provides detailed feature descriptions and pricing. However, no example 200 response body schema is documented for the /alpha/news endpoint specifically, and /docs returns 404, so the actual response structure must be inferred.

Warnings

  • —No documented 200 response schema for /alpha/news — actual response fields are unknown beyond the Meta envelope
  • —The /docs, /api, /pricing, and /README paths all return 404
  • —Example response JSON is unavailable; agents should inspect actual responses to determine structure
  • —This endpoint provides crypto market intelligence which may be used for financial decisions — it is not financial advice
