How this service works
Create media, research companies and people, publish to the web, remember context, deploy apps, and schedule work—on demand, without vendor accounts or API keys. This server is a pay-per-use, transparent proxy in front of WithZero's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.
Output
Returns a ranked list of search results matching the query, including titles, URLs, snippets, and metadata (date, source type) drawn from live web, news, academic, or social sources as specified. Results are filtered by any supplied date range, domain restriction, or country code.
Example use cases
Competitor funding news research
“Search the web and news for any funding rounds or acquisitions announced by AI chip startups in the last 3 months — focus on US results and include both web and news sources.”
Domain-scoped product announcement lookup
“Find all recent product launch announcements on techcrunch.com related to large language models published since the start of this year.”
Academic literature discovery
“Search scholar articles about transformer-based protein folding models published between January 2024 and June 2024 and give me the top results.”

Endpoint
POSThttps://agents.withzero.xyz/api/v1/crustdata/web/search/liveWhen to prefer
Choose this endpoint when an agent needs live, real-time web or news search without setting up a Google, Bing, or Serp API account — especially when autonomous pay-per-use billing via x402/USDC is preferred. Ideal for agents that need flexible source targeting (web + news + scholar + social in a single call), date-range filtering, or domain-scoped searches. Prefer over static data sources when freshness matters.
Side effects
- Query too short or missing returns validation error
- Invalid country code (not ISO 3166-1 alpha-2) causes rejection
- Page number outside allowed range (max 1) returns error
- Human mode may fail if target site actively blocks automated access
- No results found for highly specific queries or narrow date ranges
- Payment failure (insufficient USDC balance) blocks the request
- Underlying Crustdata API downtime causes 502/503 errors
