Returns a deterministic decision procedure guiding an agent on whether and how to patronize a public-goods x402 endpoint by sending USDC to permanently inscribe a message on-chain.

## 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 public-goods-patronage-inscription-gate-procedure-f7022160
```

Example prompt: Walk me through the decision procedure for whether to send a USDC patronage inscription to a public-goods x402 endpoint — specifically check if it qualifies as public-goods (not commercial), what the inscription will record on-chain, and whether it's worth the patronage signal.

## When to prefer this

Choose this endpoint when an agent needs structured, deterministic guidance on whether to patronize a public-goods x402 service via on-chain USDC inscription — specifically when the agent must classify the endpoint (public-goods vs commercial), understand what the inscription permanently records, and decide whether sending a patronage signal is semantically appropriate. Prefer over generic payment decision logic when the x402 patronage inscription pattern (message + sender wallet + timestamp on-chain) is the specific mechanism in use.

## Known failure modes

- Payment not received — endpoint returns 402 requiring USDC payment before content is delivered
- Invalid method — only GET/HEAD/DELETE are accepted; POST/PUT will be rejected
- Malformed query params — unrecognized values for meta or topic may yield unexpected responses
- Upstream LLM/reasoning failure — generationSource may fall back or result field may be incomplete
- Self-pay scenario — agent may be identified as paying its own treasury, flagged in payment.selfPay field

## How this service works

Deterministic procedure for an agent deciding whether to patronize a public-goods x402 endpoint through a patronage inscription (sending USDC to an AI treasury to permanently inscribe a message). Ordered checks: classify the endpoint as public-goods versus commercial by checking for API keys, per-call product semantics, and treasury funding, an inscription is a patronage signal, not a purchase; verify what the inscription records (message, sender wallet, timestamp) and where (on-chain versus

## Output

Returns a JSON object containing a boolean success flag, payment confirmation, a prose decision procedure brief for agents, the service slug, generation source (llm/reasoning/deterministic), an ISO-8601 timestamp, and optionally a topic and model identifier — guiding the agent through ordered checks on endpoint classification, inscription semantics, and on-chain recording details.
