# Agent Payment Adoption Measurement: EIP-712 Mandate Redemption Logs Decision Procedure > Agent Payment Adoption Measurement: EIP-712 Mandate Redemption Logs Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21). Returns a paid, LLM-generated decision procedure for measuring real agent-payment adoption using EIP-712 mandate redemption logs keyed to ERC-8004 identity, contrasted against raw USDC transfer totals as a falsifiable metric. ## Facts - Endpoint: GET https://k2so.wrong.systems/api/services/agent-payment-adoption-measurement-eip-712-manda?utm_source=zero.xyz - Price: $0.002/call - Payment: x402 - Status: unknown - Last checked: 2026-10-21 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/agent-payment-adoption-measurement-eip-712-mandate-redemption-logs-07e358ff - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ijL46sKz304TRK0ccEhFA Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## 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-payment-adoption-measurement-eip-712-mandate-redemption-logs-07e358ff ``` Example prompt: Give me a blunt decision procedure for measuring real agent-payment adoption — specifically how to use EIP-712 mandate redemption logs keyed to ERC-8004 identity as actual proof of adoption, and why raw USDC transfer totals are misleading; include inputs, thresholds, and failure modes. ## When to prefer this Choose this endpoint when you need a structured, blunt decision procedure specifically for distinguishing genuine EIP-712 mandate-based agent payment adoption from raw USDC transfer inflation, particularly when operating in the x402/ERC-8004 ecosystem. Prefer this over generic blockchain analytics endpoints when you need opinionated thresholds and failure modes rather than raw data. ## Known failure modes - Missing or invalid payment header returns 402 with payment details - Non-GET method returns method-not-allowed error - LLM generation failure may return generationSource: deterministic with reduced quality - Empty or malformed topic override may produce generic procedure rather than targeted output - meta=1 returns free metadata JSON only, not the paid decision procedure ## How this service works Paid agent-facing brief on agent-payment-adoption-measurement: EIP-712 mandate redemption logs keyed to ERC-8004 identity as real adoption proof, falsifying raw USDC transfer totals · Build a decision procedure or schema for: agent-payment-adoption-measurement: EIP-712 mandate redemption logs keyed to ERC-8004 identity as real adoption proof, falsifying raw USDC transfer totals. Include inputs, thresholds, failure modes. Fa-0. Blunt decision procedure, not marketing. ## Output A JSON object containing a plain-prose decision procedure (120+ words) titled 'brief' and 'procedure', covering inputs, thresholds, and failure modes for measuring agent-payment adoption via EIP-712 mandate redemptions vs raw USDC transfers. Also includes service slug, model used, ISO-8601 generation timestamp, and generation source enum (llm/reasoning/deterministic). Payment metadata included if paid. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET", "HEAD", "DELETE" ], "type": "string" }, "queryParams": { "type": "object", "properties": { "meta": { "enum": [ "0", "1" ], "type": "string", "description": "Set to 1 for free metadata JSON (no payment required)" }, "topic": { "type": "string", "description": "Optional topic override for the decision procedure" } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "title": "agent-payment-adoption-measurement: EIP-712 mandate redemption logs ke paid response", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "ok", "paid", "service", "provider", "result" ], "properties": { "ok": { "type": "boolean" }, "paid": { "type": "boolean" }, "result": { "type": "object", "required": [ "ok", "service" ], "properties": { "ok": { "type": "boolean", "description": "Handler success" }, "brief": { "type": "string", "description": "Decision procedure prose for agents" }, "model": { "type": "string" }, "topic": { "type": "string" }, "service": { "type": "string", "description": "Service slug" }, "procedure": { "type": "string" }, "generatedAt": { "type": "string", "description": "ISO-8601 timestamp" }, "generationSource": { "enum": [ "llm", "reasoning", "deterministic" ], "type": "string" } } }, "payment": { "type": "object", "properties": { "code": { "type": "string" }, "payer": { "type": "string" }, "detail": { … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "ok": true, "paid": true, "result": { "ok": true, "brief": "plain prose decision procedure (120+ words)", "model": "deepseek/deepseek-v4-flash-0731", "topic": "string topic", "service": "agent-payment-adoption-measurement-eip-712-manda", "procedure": "same as brief", "generatedAt": "2026-01-01T00:00:00.000Z", "generationSource": "deterministic" }, "service": "agent-payment-adoption-measurement-eip-712-manda", "provider": "K-2SO" } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/agent-payment-adoption-measurement-eip-712-mandate-redemption-logs-07e358ff/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from k2so.wrong.systems](https://www.zero.xyz/host/k2so.wrong.systems/llms.txt)
