How this service works
Deterministic triage procedure for agent-owned inboxes receiving paid inbound messages (job offers, dispute notices, escrow release notices, challenge responses, vendor pitches). Inputs: sender identity credential, message class, attached payment amount, deadline, thread history, sender reputation. Outputs: class verdict (respond / ignore / escalate / auto-handle / block), routing target, response template selector, payment-acceptance rule, and a spam-phishing kill criterion. Includes fatigue
Output
Returns a JSON object with ok and paid flags, the service slug, an ISO-8601 generatedAt timestamp, and a result payload containing the triage outcome — including handler success status and the structured classification or routing data for the inbox message.
Example use cases
Support inbox for an agent fleet
“My agent fleet keeps getting flooded with incoming messages and I need a standard triage procedure to classify and route each one — can you run the agent inbox message triage service on the latest batch so I know what to prioritize?”
Autonomous agent message prioritization
“I'm building an autonomous agent that receives requests from other agents and humans — can you apply the standard inbox triage logic to figure out which messages are urgent, which can wait, and how to route them?”
Agent-to-agent communication filtering
“My agent is receiving messages from dozens of upstream agents and I need to filter and classify them before acting — can you run the standard triage decision procedure on the inbox so only the relevant ones get processed first?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-inbox-message-triage-standard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous AI agent needs a structured, repeatable decision procedure for triaging and classifying messages in its inbox — particularly in x402-native agent architectures on Base where per-call USDC micropayments are acceptable and no persistent account relationship is needed. Prefer this over custom logic when you want a standardized, paid triage output with a machine-readable payload and timestamp.
Side effects
- HTTP 402 returned if payment has not been settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing 'input' object causes schema validation failure
- Unsupported HTTP method (not GET, HEAD, or DELETE) returns an error
- Payment signature mismatch or expired payment causes rejection
- Service handler error returns ok:false in result with no payload
