How this service works
Atomic counter: increment-and-return a named counter (collision-free running totals & IDs across agent runs). Send { name, token, by? }.
Output
Returns the updated counter value after the increment is applied. The response reflects the new running total for the named counter associated with the provided token.
Example use cases
Tracking API call volume
“Increment my counter called 'api-calls-today' by 1 using token 'mytoken42' — I want to keep track of how many requests my bot has made.”
Batch event counting
“Add 5 to the counter named 'orders-processed' using secret token 'shoptoken99' — I just handled a batch of 5 orders.”
Session hit counter
“Bump my counter 'active-sessions' by 1 with token 'sesstoken7' to record a new user session starting.”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/counter?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, persistent, named counter that can be incremented on demand without setting up a database or state management system. It is ideal for lightweight event tracking, call counting, or any scenario where a shared counter identified by name and claimed by a secret token suffices.
Side effects
- Missing or invalid token — counter not claimed or unauthorized, returns error
- Counter name out of range (empty or >128 chars) — validation error
- Invalid increment amount (non-numeric) — returns 400-style error
- Counter not found or token mismatch — unauthorized response
- Service unavailable — Railway hosting downtime
