# Agent Guild Payment Decision (AGPD-1) – Wallet Binding

> Agent Guild Payment Decision (AGPD-1) – Wallet Binding is a paid API for AI agents from agent-guild-5d5r.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a signed Verifiable Credential (AGPD-1) authorizing or denying a USDC payment based on wallet trust tier and value protection policy.

## 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-guild-payment-decision-agpd-1-wallet-binding-83cfdef0 -d '<json body>'
```

Example prompt: Before we send 500 USDC to wallet 0xAbC123… as payment for the data pipeline job, use Agent Guild to get a signed AGPD-1 payment decision so we have offline-verifiable proof the wallet passed the high-value protection policy check.

## When to prefer this

Use this endpoint when an autonomous agent needs a cryptographically signed, offline-verifiable authorization before releasing USDC to an untrusted counterparty wallet. It is especially appropriate when compliance, audit trails, or delegated trust are required — situations where a raw balance check or informal approval is insufficient. Prefer this over generic wallet lookup APIs when you need the AGPD-1 signed credential format specifically, or when integrating with the Agent Guild trust framework for multi-agent payment pipelines.

## Known failure modes

- Payment not received via x402 v2 → request rejected without decision credential
- Wallet address malformed or missing → 400 validation error
- Counterparty wallet fails trust screening → decision returned as 'deny' rather than error
- Insufficient USDC balance for $0.01 per-call fee → payment failure, no credential issued
- Network or rendering service downtime (hosted on Render free tier) → 503 or timeout
- Invalid or missing required input fields → 422 unprocessable entity

## How this service works

Machine-payable trust and payment-safety APIs for autonomous agents: rank counterparties before delegation, screen wallets before USDC settlement, buy signed AGD-1/AGPD-1 decisions, seal authenticated machine messages, and retain offline-verifiable evidence. Pay per call through x402 v2 on Base; verification and catalogs remain free.

## Output

A signed Verifiable Credential of types VerifiableCredential and AgentGuildPaymentDecision, conforming to AGPD-1/1.0 contract. The credential's credentialSubject includes: the contract identifier, a binary allow/deny decision, and a protection object detailing fee_credits (e.g. 2500), basis_points (e.g. 25), the applicable value protection contract URI, and the required_value_tier classification (e.g. 'high'). The credential is cryptographically signed and offline-verifiable.
