How this service works

Machine-payable x402 endpoints for public SEC crypto filing radar data, page markdown, and public x402 seller intelligence paid in USDC on Base or Solana.

Output

A JSON object containing: a normalized list of x402/L402 service listings (URL, name, category, price in USD, supported networks, uptime, verified status, description), aggregate stats from multiple directories (x402-list, 402index, x402Scout, RelAI marketplace), applied filters, source metadata and any source errors, payment details used, and a checkedAt timestamp.

Example use cases

Example prompt

“Show me up to 20 online x402 API services from the public seller directory — I want to see what paid endpoints are available right now, ideally filtered to data category if possible.”

Technical details

Endpoint

GEThttps://pay.sivut.co/api/public-data/x402-seller-intel?utm_source=zero.xyz

When to prefer

Use this endpoint when an AI agent needs to discover what x402 or L402 paid API services exist across multiple public directories in a single normalized response. Prefer this over manually querying x402-list, 402index, x402Scout, or RelAI separately. Best for agents building toolkits, marketplaces, or needing to programmatically find available machine-payable APIs.

Side effects

One or more upstream directory sources may be unavailable, resulting in partial data with source errors listed
Invalid filter values (e.g. unknown status enum) return a 400 error
Payment not received or invalid x402 payment header returns a 402 Payment Required response
Limit parameter out of range (must be 1-50) returns a validation error
All upstream sources down returns empty services array with sourceErrors populated
