Aggregated crypto news headlines from RSS feeds, pay-per-call via x402 on Base.
What it does
This endpoint returns the latest cryptocurrency headlines aggregated from multiple RSS feed sources including CoinDesk, The Defiant, and other crypto news outlets. It is a simple GET request with no required query parameters, returning JSON with headline data.
The endpoint is hosted on httpay.xyz, a marketplace of 300+ pay-per-call APIs settled via x402 micropayments in USDC on Base L2. Each call to /api/news/crypto costs $0.005 (5000 base units of USDC with 6 decimals). No API keys or subscriptions are needed — payment is handled inline via the x402 protocol's X-PAYMENT header. The endpoint also supports MPP (Machine Payments Protocol) settlement via pathUSD on Tempo at $0.005 per call. A free demo mode is available by appending ?demo=true (limited to 10 calls per IP per hour).
The endpoint is live and returns a standard 402 challenge when called without payment credentials. It can be integrated using the x402-fetch npm package, the @httpay/mcp MCP server for Claude/Cursor, or any HTTP client that implements the x402 payment flow. The output schema indicates JSON response type, though the exact response structure beyond headlines is not fully documented in the available material.

Quality
The endpoint is live (402 challenge confirmed) with clear pricing ($0.005/call USDC on Base) and basic schema info, but the actual response structure is not documented — the output example in the schema only contains the description string. The response JSON shown above is inferred from the landing page hint ('headlines: [...], source: "CoinDesk, The Defiant, ..."') and should be treated as approximate. No OpenAPI spec was accessible and /docs returns 404.
Warnings
- —Exact response JSON schema is not documented; the example response is inferred from landing page hints and may not match actual output
- —No OpenAPI spec accessible (openapi.json referenced in ai-plugin but not provided in probe)
- —Documentation page (/docs) returns 404
- —robots.txt disallows /api/ paths for crawlers, which may affect discoverability
