How this service works
Distributed lock: acquire a named lock for ttlSec so only one agent proceeds. Returns acquired:false if held. Send { name, token, ttlSec? }.
Output
Returns a confirmation that the named lock has been acquired (or a failure if the lock is already held), along with the lock's expiry time based on the requested TTL. The agent can use this to ensure exclusive execution of a critical section before releasing the lock.
Example use cases
Preventing duplicate trade execution
“Acquire a lock called 'solana-snipe-pump' with token 'mySecret42' and a 90-second TTL so my two trading bots don't both try to snipe the same pump.fun launch at the same time.”
Coordinating DeFi rebalance jobs
“I need to grab a distributed lock named 'portfolio-rebalance-eth' using token 'rebalancerToken99' for 300 seconds — only one of my agent workers should run the rebalance job at a time.”
Serializing oracle update writes
“Lock 'oracle-price-writer' with token 'oracleSecret7' and a 60-second TTL before I push a new price update on-chain, so no other agent instance writes a conflicting update simultaneously.”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/lock/acquireWhen to prefer
Use this endpoint when you need lightweight, pay-per-call distributed mutual exclusion across multiple AI agent instances or workers without setting up dedicated infrastructure like Redis or Zookeeper. Ideal for agent pipelines that need to serialize access to shared on-chain resources, prevent duplicate trade execution, or coordinate concurrent tasks with a simple token-based secret and automatic TTL expiry.
Side effects
- Lock already held by another caller — returns conflict or busy response
- Invalid or missing token — authentication failure
- TTL out of range (exceeds 3600s) — validation error
- Network timeout reaching the lock service — transient error
- Lock name collision with reserved names — error response
