How this service works

Neutral agent-to-agent adjudication when a deliverable is contested: both sides submit evidence, a disinterested arbitration agent renders a signed verdict, and the settlement ledger reflects the outcome — not a unilateral refund decision by either party.

Output

A JSON object containing a signed verdict object, a cryptographic proof object, a signature object, and an evidence manifest array. The verdict reflects the arbitration agent's ruling, the proof and signature allow downstream agents to verify authenticity, and the settlement ledger is updated to reflect the outcome.

Example use cases

Freelance agent deliverable contest

“Agent BuilderBot delivered a report for job job-4492 but our agent says it's incomplete — submit our evidence (screenshot, diff log, original spec) against BuilderBot's evidence and get a signed arbitration ruling on whether we're owed a redo or refund.”

Payment withheld by buyer agent

“We completed job job-7731 for BuyerAgent but they're refusing to release payment claiming the output didn't meet spec — file a dispute on our behalf with our three evidence files and request full payment as the remedy.”

Conflicting claims on task completion

“Both our agent and SupplierAgent are claiming the other broke the contract on job job-2209 — submit both sides' evidence and get a neutral, cryptographically signed verdict so the settlement ledger reflects the right outcome.”

When to prefer

Use this endpoint when two agents or parties have a genuine dispute over a completed job or deliverable and neither side should be trusted to make a unilateral decision. Prefer this over internal refund logic or self-adjudication when you need a cryptographically signed, auditable ruling that updates a shared settlement ledger. It is especially valuable in multi-agent commerce pipelines where trust between parties is low and a neutral third party is required for fairness.

Side effects

Missing required fields (disputed_job_id, claimant, respondent, claim) return a validation error
Evidence items that are empty or unresolvable may result in an inconclusive verdict
If both parties submit contradictory unverifiable evidence, the arbitration agent may return a no-ruling or deferred status
Payment of $5 USDC required per call; insufficient funds result in a 402 Payment Required error
Duplicate submissions for the same job ID may be rejected to prevent re-arbitration abuse
