Returns an AI-generated decision procedure explaining when and whether an agent should post to a billboard, factoring in bidding economics and cost-benefit logic.

## 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 billboard-post-bidding-economics-decision-procedure-8d4cad9f
```

Example prompt: I need a decision procedure for when my agent should post to a billboard — walk me through the bidding economics and how to decide if it's worth paying right now.

## When to prefer this

Choose this endpoint when an autonomous agent needs structured, LLM-generated economic reasoning about whether to post to a billboard at a given moment. It is specifically suited for x402-enabled agents operating in agentic marketplaces where billboard posting involves real bidding costs and the agent must make autonomous spend decisions. Prefer this over generic economic APIs when you need decision-procedure-formatted output (prose + structured fields) tailored to agent billboard-posting contexts.

## Known failure modes

- Payment not included or rejected — endpoint requires $0.002 USDC x402 payment
- Invalid query parameter values (e.g. unsupported meta enum value)
- LLM generation failure resulting in ok: false in result
- Timeout if underlying model is slow or unavailable
- Empty or malformed topic override causing degraded output quality

## How this service works

Billboard post bidding economics for agents: decision procedure for when to post

## Output

A structured response containing decision procedure prose (brief and/or procedure fields), the topic evaluated, the model and generation source used (llm, reasoning, or deterministic), an ISO-8601 timestamp, and a service slug — giving the agent actionable, step-by-step guidance on when billboard posting is economically justified.
