How this service works
Buyable: one URL, one card. Unpaid 402 dry-read. Says if a stock x402 v2 EVM client can pay. Does not settle. Does not send funds. Informational only. Not an endorsement of the resource. Not a guarantee a later settle will succeed.
Output
A plain-text response indicating whether a stock x402 v2 EVM client is capable of paying for the given URL, based on the 402 response headers and payment details returned by the target resource. No payment is settled; this is an informational dry-read only.
Example use cases
Pre-flight x402 payment feasibility check
“I want to call a paywalled API at https://api.dataprovider.com/feed but I'm not sure if my x402 client supports it — can you do a dry-read check on that URL to see if it's payable without actually sending any money?”
Debugging 402-gated resource integration
“I'm integrating an x402-enabled resource at https://content.myservice.io/report and something seems off — can you probe it to tell me if a standard x402 v2 EVM client could theoretically pay for it, without settling?”
Validating x402 compatibility before agent workflow
“My automated agent is about to start paying for resources, but first I need to know if https://premium.feeds.io/data is compatible with x402 v2 on EVM — just check payability without committing any funds.”
Technical details
Endpoint
GEThttps://api.premiumrewards.vip/buyableWhen to prefer
Use this endpoint when you need to determine upfront whether a URL is payable by a standard x402 v2 EVM client before committing any funds or triggering a full payment flow. Prefer this over actually attempting payment when you want to validate compatibility, debug 402 integration issues, or gate an agent workflow on confirmed payability.
Side effects
- Target URL does not return a 402 response, indicating it is not x402-gated
- Target URL is unreachable or times out
- x402 payment details in the 402 response are malformed or incompatible with v2 EVM spec
- Missing required 'url' query parameter returns an error
- The endpoint itself requires $0.01 USDC payment and will return 402 if unpaid
