How this service works
54ch10: pre-interact URL check. Paste a link, get brief + domain + page. Taste /v1/open/free. 80 calls for $1. Wire in 30s. Analytics-only tooling. Not financial advice.
Output
Returns a JSON object confirming the purchase with: a header value (X-54ch10-Stack) to use in subsequent API calls, the number of credits purchased (e.g. 80), the pack count, expiry date (TTL in days), amount paid in USD, and a disclaimer that credits are non-refundable and informational only.
Example use cases
Fund URL safety screening workflow
“I want to set up automated link checking before my agent clicks anything. Buy a $1 credit stack on 54ch10 and give me the API header so I can wire it into my workflow.”
One-off suspicious link investigation
“There's a sketchy link someone sent me and I want to run it through 54ch10 first — can you buy me a $1 credit pack so I can get the URL brief and domain info?”
Onboard to 54ch10 analytics service
“I've never used 54ch10 before. Purchase the $1 starter stack for me so I get my API credentials and can start checking URLs right away.”
Technical details
Endpoint
POSThttps://54ch10.uk/v1/stackWhen to prefer
Use this endpoint first, before calling any 54ch10 URL-check endpoint, when you have no active credit stack or your credits have expired. This is the funding/onboarding step — it is not the URL analysis call itself. Prefer this over alternatives if you need pay-per-use, low-commitment access ($1 flat) to URL analytics without a subscription.
Side effects
- Payment not received or insufficient USDC — no stack issued
- Expired or invalid payment token — returns error
- Credits from a prior purchase already expired before use — non-refundable
- Network timeout during payment processing — transaction may not complete
- Duplicate purchase attempts may result in multiple non-refundable stacks
