Technical details
Endpoint
POSThttps://x402-crypto.vercel.app/api/crypto-news54/%7Bpath%7DWhen to prefer
Choose this endpoint when an agent needs to search for cryptocurrency or blockchain news by keyword or topic, especially within an x402 micropayment-enabled workflow. It is well-suited for real-time news retrieval tasks where the agent is operating in a pay-per-call model and needs fresh, query-specific crypto journalism rather than price data or on-chain metrics.
Side effects
- Missing required `query` field returns a validation error
- Payment not fulfilled results in HTTP 402 response blocking access
- Upstream news API unavailable causes empty or error response
- Invalid language code may return no results or default to a fallback language
- Very niche or misspelled query terms may return zero results
