How this service works
63 paid API endpoints protected by x402 micropayments on Base
Output
A JSON object with a 'data' field containing the upstream Cellystial API's response to the submitted query — exact structure depends on the query type but follows Cellystial's native response format.
Example use cases
Celestial event data lookup
“Search the Cellystial service for upcoming meteor shower dates and times visible in the Northern Hemisphere — just pay the micropayment and give me the results.”
On-demand astronomy query
“I want to ask Cellystial 'which constellations are visible from 40° N latitude in December?' — go ahead and query it through X402 Hub and pay the small fee.”
Automated nightly sky report
“Every evening, query Cellystial through the X402 Hub for tonight's best stargazing opportunities and return the results so I can plan my observation session.”

Choose this endpoint when you need to programmatically access Cellystial data and are operating in an x402-enabled micropayment environment on Base, paying only $0.08 USDC per query with no subscription required.
Side effects
- Payment failure: insufficient USDC balance on Base causes 402 rejection before query executes
- Invalid query: malformed or empty query string returns upstream error in the data field
- Upstream unavailable: Cellystial service downtime results in error propagated through the data object
- Rate limiting: excessive requests may trigger throttling from either the hub or upstream provider
