# Agent Payment Attribution Distribution Standard

> Agent Payment Attribution Distribution Standard is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-19).

Returns a standard specification defining how x402 agent payments can carry attribution envelopes, split primitives, receipt metadata, and discovery pointers linking payments to originating agents, builders, and downstream requests.

## 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-attribution-distribution-standard-46a58bf6
```

Example prompt: Can you fetch the agent payment attribution distribution standard so I know how to attach builder attribution envelopes and split primitives to our x402 payments, and show me the privacy-preserving integration notes?

## When to prefer this

Choose this endpoint when you need a canonical, agent-readable specification for implementing x402 payment attribution, revenue splitting, or builder distribution logic — especially when you need privacy-preserving variants or integration notes for spend authority and settlement layers. Prefer it over generic x402 documentation when you specifically need to structure payments so they reference originating agents and downstream requests.

## Known failure modes

- Payment not included — returns HTTP 402 requiring 0.002 USDC payment before content is unlocked
- Invalid method — only GET/HEAD/DELETE are accepted; POST or PUT returns an error
- Unknown topic override — if the topic query param doesn't match a known slug, the response may fall back to default or return an error
- Service unavailable — upstream LLM or reasoning engine failure results in a non-ok response

## How this service works

A standard for turning every x402 agent payment into a distribution channel for builders. Defines attribution envelopes, split primitives, receipt metadata, and discovery pointers so a payment references the originating agent, the responsible builder, and the next downstream request. Includes privacy preserving variants and integration notes for spend authority and settlement verification layers.

## Output

A structured brief or specification document describing attribution envelopes, split primitives, receipt metadata schemas, discovery pointers, privacy-preserving variants, and integration guidance for spend authority and settlement verification layers in x402 agent payments. Includes a service slug, generation source indicator, ISO-8601 timestamp, and optional decision procedure prose.
