How this service works
Autonomous bill-negotiation phone calls for agents.
Output
The agent receives the outcome of the negotiation phone call, including whether a lower rate was secured, the new negotiated monthly amount if successful, and optionally a callback notification to the provided URL with the full result details.
Example use cases
Lower monthly cable TV bill
“Call the retention line for my Spectrum cable TV plan and negotiate my bill down — I'm currently paying $120 a month and want to get it under $80. My account number is 987654321, the account is under John Smith, and the PIN is 3391.”
Reduce internet service rate
“My AT&T internet bill just jumped to $95 a month after my promo expired. Can you call their retention department at +18009192000 and get me a better rate — ideally around $60? Account is under Sarah Johnson, account number 456789123, PIN is 7712.”
Negotiate lower phone plan cost
“I've been on the same Verizon plan for two years and I'm paying $85 a month — way too much. Call their retention line and see if you can get that down to $55 or less. My account number is 112233445, it's under Mike Torres, and my account PIN is 5508.”
Technical details
Endpoint
POSThttps://bill-negotiation-api.lewis-6d8.workers.dev/negotiate?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user wants to autonomously reduce a recurring monthly bill (telecom, cable, internet, utilities) without manually calling the provider themselves. Best suited for services that have a known retention phone number and account credentials. Prefer this over manual negotiation scripts or chat-based alternatives when a live phone call to a retention department is required.
Side effects
- Retention line is unreachable or goes unanswered — call fails with no negotiation outcome
- Account PIN or account number is incorrect — provider refuses to authenticate
- Provider retention team declines to offer any discount — negotiation unsuccessful
- Invalid E.164 phone number format causes request validation error
- Callback URL is unreachable and result notification fails to deliver
- Account holder name does not match provider records — call rejected
