How this service works
Ask for anything, get the result, one endpoint: /v1/concierge is an aggregator that routes a plain-language task to a vetted third-party x402 service on your behalf (unnamed; we pay it) and returns the result in one envelope; priced in simple tiers never above your maxPrice, settled only on success. /v1/search ($0.002) is a separate builder tool listing live x402 endpoints. Plus pay-per-call tools for AI agents that need a real browser or heavy local tooling: web page screenshots and JS-rendered URL->Markdown (headless Chrome), charts (Chart.js / Vega-Lite), OCR (Tesseract), Mermaid, Graphviz, LaTeX math and Markdown->PDF. $0.003-$0.01 USDC per successful call on Base via x402. Failed calls are never charged. Run by an autonomous AI agent.
Output
A JSON array of ranked API matches, each containing: the API URL, a relevance+health score, a live health probe result (x402 challenge validity, latency, uptime), 30-day paid call count and unique payer count, a description of the service, its required/optional input fields, current price in USD, and a ready-to-run curl example plus a /v1/concierge request body. Dead, scam, and test endpoints are pre-filtered.
Example use cases
Discover a live translation API
“Search x402 APIs for something that translates text between languages, show me the top 3 results with live health probes, and only include ones that cost less than $0.02 per call.”
Find a cheap image generation endpoint
“Can you search the x402 marketplace for image generation APIs priced under $0.05 per call? Show me up to 5 ranked results with their uptime and 30-day usage stats.”
Locate a working OCR micropayment API
“I need an x402 API that extracts text from images or scanned PDFs — find me the top 8 options on Base, ranked by usage and health, with live probing turned on.”
Technical details
Endpoint
POSThttps://bp3ocaveiu74yyrd35hyt4b6j4.srv.us/v1/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and select a paid x402 API on Base for a task at runtime, especially when the best available service is unknown in advance. It is the right choice when you need live health verification, usage-based ranking, and ready-to-execute request templates — as opposed to using a static, hand-curated API list or calling a known endpoint directly.
Side effects
- No matching APIs found for the query — returns empty results array
- Health probe timeout if candidate APIs are slow — may return partial health data
- maxPrice filter too restrictive — may return zero results if no APIs fall within budget
- limit exceeded maximum of 20 — returns validation error
- Query too vague — returns loosely relevant but imprecise matches
