Payment-gated trending crypto token and sector intelligence with narrative clustering and social momentum.
What it does
The /alpha/trending endpoint on the x402 Meta Gateway returns trending tokens ranked by volume, with AI-generated analysis of why they're moving. It aggregates data from multiple live sources including CoinGecko, DexScreener, X/Twitter, and others, delivering structured JSON with narrative clustering and social momentum signals.
This endpoint is part of a broader crypto intelligence API (x402.911fund.io) that offers 14+ tools covering token analysis, sentiment, prediction markets, macro economics, on-chain activity, risk assessment, and more. The /alpha/trending endpoint accepts optional query parameters: `category` (e.g. "defi"), `limit` (1–50 results), and `twitter` (boolean to include X/Twitter sentiment addon). Payment is $0.03 USDC per call, settled via the x402 protocol on either Base (EIP-155:8453) or Solana mainnet.
Responses are wrapped in a standardized envelope that includes metadata such as request_id, sources_used, confidence score, time_window, and warnings. The endpoint returns 422 with no charge when clarification is needed, and uses structured error codes (invalid_params, upstream_failed, rate_limited, etc.) for failure cases. The same tools are also accessible via an MCP JSON-RPC interface at /mcp for native AI agent integration.

Quality
Full OpenAPI 3.1 schema is available with well-defined parameters, error envelopes, and a live 402 challenge confirming the endpoint is operational. Pricing is clear ($0.03 USDC). However, no 200 response schema is documented, and no example successful response body is available, so the exact output structure must be inferred from the landing page description.
Warnings
- —No documented 200 response schema — the structure of successful responses is not formally specified in the OpenAPI spec.
- —The /docs, /api, /pricing, and /README paths all return 404, so there is no dedicated documentation site beyond the landing page.
- —Response examples on the landing page are only shown for /alpha/token, not /alpha/trending specifically.
