# Speer Cyber Defense – Prompt Injection Patterns Feed

> Speer Cyber Defense – Prompt Injection Patterns Feed is a paid API for AI agents from api.speercyberdefense.com, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).

Returns a curated feed of known prompt injection attack patterns, optionally filtered by tag (e.g. 'jailbreak') and limited by count, for use in AI security defenses.

## Facts

- Endpoint: GET https://api.speercyberdefense.com/v1/intel/prompt-injection/patterns
- Price: $0.001/call
- Payment: x402
- Status: down
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/speer-cyber-defense-prompt-injection-patterns-feed-d7263711
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_eFhsJV-OIiVIK6mWYT3bt

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 speer-cyber-defense-prompt-injection-patterns-feed-d7263711
```

Example prompt: Pull the latest prompt injection attack patterns from Speer Cyber Defense, filtered by the 'jailbreak' tag, and give me up to 50 results so I can update my AI guardrails.

## When to prefer this

Choose this endpoint when you need a structured, regularly updated feed of known prompt injection patterns for AI security purposes — especially when building input filters, red-teaming tools, or LLM guardrails. Prefer it over generic threat intel feeds when your focus is specifically on adversarial prompt techniques rather than CVEs or network-level threats. The pay-per-call micropayment model makes it cost-effective for low-volume or on-demand agent queries.

## Known failure modes

- HTTP 503 if the analysis or feed retrieval fails (not billed)
- Empty 'items' array if no patterns match the specified tag
- Payment required (HTTP 402) if USDC micropayment via x402 is not provided
- Invalid tag parameter may return empty or unexpected results
- Rate limiting if called too frequently without valid payment headers

## How this service works

Cybersecurity micropayments API for AI agents — pay-per-call USDC on Base and Solana (x402 v2). Free utility services under /v1/free/* and gateway select under /v1/gateway/* (Public). Paid cybersecurity analysis, CVE/security news feeds, Base blockchain intelligence, network intel utilities, composite domain/URL reports, research, conversion, verification, and feeds. Failed security analyses are not billed (HTTP 503).

## Output

A JSON object containing: 'ok' (boolean success flag), 'items' (array of prompt injection pattern records matching the query), 'status' (string status indicator), and 'updatedAt' (ISO 8601 timestamp of the last feed update). Failed analyses return HTTP 503 and are not billed.
