# Agent Identity Presentation and Cold-Start Facilitator Trust Procedure

> Agent Identity Presentation and Cold-Start Facilitator Trust Procedure is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-18).

Returns a deterministic decision procedure guiding an agent on which wallet identity to present to a given counterparty class, based on reservation credential status, reputation, and task sensitivity.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-identity-presentation-and-cold-start-facilitator-trust-procedure-be829d6c
```

Example prompt: For a new transaction with an unknown facilitator counterparty, run the agent identity presentation procedure and tell me whether to reveal my reserved wallet ID or fall back to a pseudonymous identity given that my reservation credential is valid but there's no prior reputation record and the task sensitivity is high.

## When to prefer this

Use this endpoint when an autonomous agent holds a Cloudflare programmable wallet reservation and needs a structured, deterministic policy for which identity to expose to a new or unverified counterparty. Especially valuable in cold-start scenarios with no prior reputation data, high-sensitivity tasks, or when the agent must decide whether a counterparty passes a reservation credential anchor check before revealing a readable reserved ID.

## Known failure modes

- Missing or invalid reservation credential causes fallback to pseudonymous identity path
- Unknown counterparty class not matching defined enum may result in default conservative policy
- Payment not received (402) returns no decision data — agent must settle x402 payment first
- Topic override not recognized may cause generic procedure to be returned
- LLM generation failure may result in 'deterministic' fallback with reduced nuance

## 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 decision procedure prose brief ('brief'), the generation source (llm, reasoning, or deterministic), the topic, service slug, and an ISO-8601 timestamp. The 'procedure' field provides step-by-step rules the agent should follow for identity presentation. Payment metadata including transaction reference and payer is also returned.
