x402 API benchmark for pricing, buying, and listing decisions

This page keeps the first real paid attempt on one route: GET /v1/market/hot-categories?intent=market_research.

What this page shows

It shows the exact $0.02 route, unpaid 402 probe, paid retry placeholder, payment-capable client prompts, and what counts as real M1A demand.

What the paid API adds

The paid response ranks active x402 categories by visible market activity, confidence, density, and suggested follow-up benchmark inputs.

Who should use it

Use it if you have Base MCP, Coinbase Bazaar MCP, AgentCore Bazaar, @x402/fetch, x402scan wallet flow, or another x402-capable buyer client.

Example use cases

Move from anonymous 402 probes to one deliberate paid retry from a real buyer wallet or agent payment client.

Why the data is useful

The route is useful because it is the smallest paid proof that PricePilot402 can return decision-grade x402 market data after payment.

What the buyer gets after payment

After payment, the buyer gets structured JSON with hot categories, activity explanations, confidence, and follow-up route inputs.

Clear next action

Dry-run the 402 challenge first. Only send the paid retry after your buyer client has read PAYMENT-REQUIRED and approved a max payment of 0.05 USDC or less.

Only first route

First honest paid x402 call: GET /v1/market/hot-categories?intent=market_research.

This is the hero path until the first non-internal paid retry lands. It costs $0.0200 and should be called with a max payment cap of 0.05 USDC or lower.

Decision Preview

Decision Preview

Example only - not a live paid result. Paid responses start with a recommendation, not just metrics. If data is thin, the response says so; alternatives are only shown when a stronger comparable endpoint exists; historical/source freshness is included when enough observations exist.

Unpaid 402 probe

Run this first. It should return HTTP 402, a PAYMENT-REQUIRED header, a probe_id, Base mainnet, USDC, and amount 20000. This is API intent, not demand.

curl -i "https://pricepilot402.pricepilot402-arya.workers.dev/v1/market/hot-categories?intent=market_research&limit=10&pp_ref=dist_view_00082ea4-78e0-453e-97d9-ca326f24bbdd"

Paid retry placeholder

Only run a paid retry when your x402 client has created a valid payment proof from the PAYMENT-REQUIRED challenge. Do not paste private keys or raw proofs into public chat.

curl -i "https://pricepilot402.pricepilot402-arya.workers.dev/v1/market/hot-categories?intent=market_research&limit=10&pp_ref=dist_view_00082ea4-78e0-453e-97d9-ca326f24bbdd" \
  -H "PAYMENT-SIGNATURE: <x402 payment proof>"

Base MCP prompt

Call this x402 endpoint and pay up to 0.05 USDC:
https://pricepilot402.pricepilot402-arya.workers.dev/v1/market/hot-categories?intent=market_research

Use initiate_x402_request with method="GET" and maxPayment="0.05".
After I approve the Base Account link, use complete_x402_request with the returned requestId.
Do not count the unpaid 402 challenge as demand.

Coinbase Bazaar MCP prompt

Use Coinbase Bazaar MCP search_resources for "PricePilot402 x402 market benchmark".
If the PricePilot402 hot-categories tool is found, call proxy_tool_call for:
GET /v1/market/hot-categories?intent=market_research
Set max payment to 0.05 USDC. The expected route price is 0.02 USDC.

AgentCore Bazaar prompt

agentcore add gateway-target \
  --name CoinbaseBazaar \
  --type mcp-server \
  --endpoint https://api.cdp.coinbase.com/platform/v2/x402/discovery/mcp \
  --gateway MyGateway

agentcore deploy

Then ask the agent to search for PricePilot402 and call only:
GET /v1/market/hot-categories?intent=market_research
with maxPayment 0.05 USDC.

@x402/fetch CLI commands

cd examples/x402-buyer-cli
npm install
node index.js --dry-run

# Optional real payment only after deliberate approval:
set your buyer wallet env var locally, then run:
node index.js --pay --max-payment 0.05

x402scan path

Open the PricePilot402 x402scan listing and choose the hot-categories route first if the embedded wallet flow is available.

x402 API benchmark FAQ

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.

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.
