## 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 solana-spl-asset-model-verification-before-agent-payment-7155aa6a
```

Example prompt: Give me the decision procedure for verifying a Solana SPL asset model before my agent makes a payment — I need the inputs, thresholds, and failure modes laid out clearly.

## When to prefer this

Choose this endpoint when an AI agent needs a structured, actionable decision procedure for Solana SPL asset verification before committing payment, and free Solana/SPL documentation does not provide a ready-made decision schema with explicit thresholds and failure modes. Particularly useful for agent pipeline builders who need machine-readable or prose-formatted verification gates in autonomous payment flows on Solana.

## Known failure modes

- Payment not received or insufficient — returns 402 with payment details required
- Topic override not recognized — may return generic SPL verification procedure
- LLM generation failure — generationSource may fall back to deterministic or return error
- Free public documentation already covers the decision — paid result may not add value (stated falsifier)
- Malformed query parameters — input validation error returned

## How this service works

Paid agent-facing brief on solana-spl-asset-model-verification-before-agent-payment · Build a decision procedure or schema for: solana-spl-asset-model-verification-before-agent-payment. Include inputs, thresholds, failure modes. Falsifier: If free docs already solve the decision, paid product fails.-0. Blunt decision procedure, not marketing.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) covering inputs, thresholds, and failure modes for verifying Solana SPL asset models before an agent payment. Includes the model used for generation, ISO-8601 timestamp, and generation source (llm, reasoning, or deterministic). The 'brief' and 'procedure' fields contain the actionable content.
