# Blackwood News Briefing > Blackwood News Briefing is a paid API for AI agents from x402-gateway.blackwoodstate8.workers.dev, paid per call via x402, $0.04/call, status unknown (last checked 2026-10-19). Returns a structured research briefing on a topic by fetching, reading, and summarizing up to 3 recent GDELT news articles in a single call ## Facts - Endpoint: POST https://x402-gateway.blackwoodstate8.workers.dev/v1/news-briefing?utm_source=zero.xyz - Price: $0.04/call - Payment: x402 - Status: unknown - Last checked: 2026-10-19 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/blackwood-news-briefing-40941c81 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_uUHiy21pPLunJU2Zols80 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 blackwood-news-briefing-40941c81 -d '' ``` Example prompt: Give me a news briefing on stablecoin regulation from the last 48 hours — summarize the most recent press coverage in English. ## When to prefer this Use this endpoint when you need a synthesized research briefing with full article summaries on a topic — not just headlines. Prefer it over raw news search endpoints when you want the articles read and summarized in one call. Do not use for breaking news (too slow), paywalled articles, or fetching a single known article URL (use the webpage markdown endpoint instead). ## Known failure modes - No recent GDELT articles found for the topic within the time window - Article URL is paywalled or inaccessible — appears in skipped list with reason - Topic string too short or too long (violates minLength/maxLength) - Hours value out of range (must be 1–72) - Slow response due to live article fetching — p95 around 15 seconds - Payment failure if USDC balance is insufficient ## How this service works Use when you need a news briefing, a research summary of recent coverage or an analysis of what the press says about a topic or company. Do not use for breaking news, paywalled pages or one known article (use blackwood_webpage_markdown). Returns JSON with a research briefing on a topic in one call: up to 3 recent GDELT news articles, each read and summarized, with source and link, below the price of separate calls for 0.04 USDC per call. Typical response time 15000 ms (p95).
