## 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 injective-rail-x402-agent-integration-procedure-e351d132
```

Example prompt: Give me a decision procedure brief for integrating my autonomous agent with the Injective rail using x402 micropayments — I need the full step-by-step guidance in plain prose.

## When to prefer this

Choose this endpoint when an autonomous agent needs authoritative, AI-generated procedural guidance specifically for integrating with the Injective blockchain rail via the x402 micropayment protocol. Prefer it over generic documentation lookups when you need a concise, agent-consumable prose brief rather than raw docs, and when you are already operating within the x402 payment ecosystem on Base/USDC.

## Known failure modes

- HTTP 402 returned if payment not settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing 'input' object returns schema validation error
- Unsupported HTTP method (only GET/HEAD/DELETE allowed) returns error
- LLM generation failure may return ok:false with error detail in result
- Stale or unavailable generation source may fall back to deterministic procedure

## How this service works

Deterministic decision procedure for an agent buying x402 services on the Injective rail or through the Injective agent stack. Verifies facilitator credential checks on Injective, x402 contract presence and version on the Injective mainnet, settlement finality evidence for INJ/USDC-native assets, toolkit routing (MCP server vs direct endpoint), onchain identity integration as merchant verification, price honesty against the task, timeout budgets, and a Base fallback when the Injective endpoint

## Output

A JSON object containing a paid decision procedure response with 'ok' and 'paid' booleans, a 'result' object holding a 120+ word plain-prose 'brief' (the decision procedure), the topic, the LLM model used, a generation source enum (llm/reasoning/deterministic), an ISO-8601 generatedAt timestamp, the service slug, and provider name 'K-2SO'.
