What is an x402 API benchmark?
An x402 API benchmark compares paid API endpoints that use HTTP 402 payment flows, including observed price, activity, visible GMV, confidence, and comparable market context.

x402 API benchmark for pricing, buying, and listing decisions
Use this comparison page to see the public sample. Use the paid API to turn the sample into route-specific benchmark JSON.
What this page shows
This public comparison page shows active endpoints, price range, relevant categories, source confidence, and the route that best matches this market slice.
What the paid API adds
The public page shows market summaries. The paid API returns structured benchmark fields an agent can use directly.
Who should use it
Use this API when deciding whether to list, price, buy, or benchmark an x402 endpoint.
Example use cases
Compare a market slice, choose a benchmark category, evaluate Base USDC x402 activity, and prepare a paid route call.
Why the data is useful
The data is useful because it narrows a broad public market into a specific benchmark route and example input.
What the buyer gets after payment
Paid responses include comparable endpoint clusters, price dispersion, payer density, GMV estimates, opportunity flags, and source trail.
Clear next action
Use the route-specific API block to open the buyer CTA or request a 402 challenge when the route is GET.
Route-specific benchmark output
The paid category benchmark compares all tracked endpoints in this category and returns price percentiles, payer density, GMV range, seller concentration, and decision notes.

Full Phase 1 remains locked. These blocks show only route-specific docs and capped provisional availability.

x402 API benchmark FAQ
What does the paid API return?
The paid API returns structured JSON for agents and scripts, including comparable endpoint clusters, price dispersion, payer density, visible GMV estimates, opportunity flags, confidence, and source trail where supported.
How is this different from public marketplace listings?
Public marketplace listings usually show one seller or endpoint at a time. PricePilot402 connects listings into category, endpoint, and market benchmarks so buyers can compare price and activity across similar x402 APIs.
Can agents call this API?
Yes. Agents can read the public pages, inspect OpenAPI and x402 metadata, request a 402 challenge, pay with an x402-compatible Base USDC flow, and retry the same route for JSON benchmark output.
What payment network does it use?
The provisional live routes use Base mainnet USDC through x402 metadata. Full Phase 1 remains locked while capped provisional routes stay under the configured price and usage limits.
