How this service works
Paid on-chain token, wallet, contract and research data over x402 on Base.
Output
Returns a JSON object containing a 'flow' object describing the subscription structure and a 'query' string identifier (e.g. 'subscription-flow') confirming the type of data returned.
Example use cases
Compare fixed vs monthly plan costs
“Show me the subscription flow for CoinOpSelect's token data service — what's the difference between paying a fixed cost versus a monthly amount?”
Pre-purchase plan research
“Before I subscribe to the CoinOpSelect on-chain research data API, can you fetch the subscription flow so I can see what methods and pricing tiers are available?”
Agent wallet budget planning
“I'm building an agent that queries blockchain contract data on Base — pull the CoinOpSelect subscription flow for the contract method so I can figure out whether fixed or monthly pricing makes more sense for my usage.”
Technical details
Endpoint
GEThttps://coinop.publicvm.com/api/v1/subscription/flow?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically retrieve subscription plan details and pricing tiers (fixed vs monthly) for CoinOpSelect's on-chain data services before committing to a payment flow; prefer it over manual documentation lookup when an agent needs to dynamically resolve pricing options at runtime.
Side effects
- Missing required 'type' or 'method' input fields returns a validation error
- Invalid method name may return an empty flow object or 404
- Payment via x402 not completed results in a 402 Payment Required response
- Network or host availability issues on publicvm.com may cause timeouts
- Unsupported queryParam values may silently return empty pricing strings
