How this service works
Deterministic procedure for an agent that holds a reserved wallet identity (Cloudflare programmable wallet reservation, issuer-signed agent identity tag) and must decide which identity to present per counterparty. Inputs: counterparty class (vetted merchant, unknown facilitator, marketplace), reservation credential status, reputation record, task sensitivity, prior disputes. Rules: present readable reserved ID only to counterparties passing an anchor check on the reservation credential; fall
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) for AI agents covering agent identity presentation and cold-start facilitator trust on x402 rails, along with metadata: the generating model name, topic, service slug, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and payment confirmation fields.
Example use cases
Cold-start facilitator trust bootstrapping
“My agent needs to connect to a new x402 facilitator it has no history with — what's the recommended step-by-step procedure for establishing trust and presenting its identity?”
Agent identity governance policy design
“I'm building an autonomous agent fleet on Base and need a clear decision procedure for how each agent should present its identity when calling x402 APIs for the first time — can you get me the formal guidance?”
Auditing agent onboarding compliance
“We're auditing our agents' onboarding flows for x402 compliance — fetch the standard decision procedure brief for agent identity presentation and cold-start facilitator trust so I can compare it against what we're doing.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-identity-and-new-rail-trust-decisions-for?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous AI agent needs authoritative, LLM-generated procedural guidance specifically for x402 agent identity presentation and cold-start trust establishment — particularly useful for agents bootstrapping onto the x402 payment rail for the first time or implementing governance around new facilitator relationships. Prefer over generic documentation lookups when you need a structured, actionable brief in machine-readable JSON format that an agent can parse and act on directly.
Side effects
- HTTP 402 returned if USDC payment not yet settled — agent must pay exact amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing method enum causes schema validation failure
- topic override ignored or misinterpreted if malformed string
- Generation source may be 'deterministic' rather than live LLM if cached
- Network timeout on Base USDC settlement delays retry loop
