News & Content APIs

Otto AI · Crypto News

x402.ottoai.services

Importance-ranked crypto headlines with per-article source links and publish times, plus a sentiment-scored market brief. Regenerated hourly; meta carries the snapshot's age and a fresh/stale verdict.

Curated stock-market news with ticker tags, source, publisher, image, and timestamps. Pass `?ticker=AAPL` to filter. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

Otto AI · Equity News

x402.ottoai.services

Latest company news for a vendor-resolved equity: licensed Finnhub headlines from the trailing seven days with publication time, source, and summary. Only articles that name the company are served — labelled `primary` when the headline names it, `mentioned` when only the summary does — so a symbol-tagged story about another company never fills the list. Redirect URLs withheld; no sentiment is fabricated.

Search podcasts. Searches the podcast catalog by show name — the canonical podcast search.

Latest news headlines and summaries for a stock ticker from real Yahoo Finance data. Includes article title, summary, publish date, publisher name, and URL — everything needed to monitor sentiment and catalysts. Supports optional limit parameter (default 10, max 50). $0.005/call.

Restore Hunger for an active Omniguchi. Any verified payer may care for any hatched target.

Real-time news search for AI agents. Returns recent news articles (title, link, snippet, published date) as JSON from a multi-engine news metasearch. Pay-per-query in USDC via x402 — no signup, no API key. Use for current events, breaking news, monitoring, and time-sensitive facts.

Otto AI · Filtered News

x402.ottoai.services

AI-filtered crypto news and Twitter search for non-token topics (airdrops, DeFi trends, etc). Max 2 words.

Paid JSON for one Substack-backed newsletter, blog, or podcast post: synthesized summary (`synthesizedSummary`), metadata, and identifiers for financial analysis. Path params are `publicationSlug` and `postSlug`. Returns 503 until summary exists. USDC `exact` x402 on Base or Solana; USD amount is per-post when set on the post, otherwise the server default.

Otto AI · News Recaps

x402.ottoai.services

A tight 4-6 sentence crypto market recap an agent can ingest whole — direction and why, the 2-3 developments that matter, anything notable on the top-10 board — plus the ranked stories as typed fields: stories[] (rank, title, whyItMatters, url, publishedAt, source; linked by exact title, null when unmatched).

Live feed of freshly-detected malicious addresses on Base — address-poisoning seeders caught via zero-value transfer sprays, updated continuously by our on-chain collector. Poll ?since=<unix> to ingest only new threats into your agent's blocklist. Deterministic, evidence-backed, machine-readable.

RSS and Atom feed parser — any feed URL into clean structured items (title, link, date, summary); news feed API.

Live reliability feed of x402 endpoints on Base: which services are up, return a valid 402 envelope, and how fast — free-probed across the CDP Bazaar catalog. A real share of listed endpoints are broken/misconfigured; poll ?since=<unix> (or ?health=healthy) to route your agent to endpoints that actually work. Objective measurement, no accusation, machine-readable.
