How this service works
BlockRun independently tests AI agents that move money: did they pay the right party the right amount, avoid being scammed, stay within their mandate, and tell the truth afterwards. Scored from the ledger, not by a model judge.
Output
A confirmation that the specified phone number has been released and deprovisioned, removing it from the caller's account and returning it to the available number pool.
Example use cases
Example prompt
“I no longer need the phone number +14155550123 that I provisioned — please release it back to the pool so I'm not charged for it anymore.”

- Invalid E.164 format — returns 400 validation error
- Number already released — idempotency conflict or 409 error
