How this service works
Reads the public x402 Bazaar catalogue and finds offers comparable to yours, either from a resource_url whose 402 challenge is fetched without paying, or from a category and description you supply. Every comparable offer is listed with its price, its provider host, a similarity score and the terms both sides share, so comparability is justified rather than asserted; the formula, its weights and the inclusion threshold are stated in the answer. Prices are aggregated as median, p25 and p75 over co
Output
Returns the endpoint's own price, the median, 25th and 75th percentile prices across comparable offers, a market position label (below/market/above), a list of comparable endpoint objects ranked by similarity, the detected category, sample size, and any caveats or unavailable fields.
Example use cases
Pricing a new x402 endpoint
“I'm about to launch an x402 endpoint for market data and plan to charge $0.005 USDC. Can you benchmark that price against up to 10 comparable market data offers in the x402 catalog so I know if I'm priced right?”
Checking competitiveness of live endpoint
“My live endpoint at https://x402.halowerk.com/summarize is already on the x402 network — can you fetch its price automatically and compare it against similar text summarization endpoints, showing me the top 5 comparables?”
Researching x402 market rates before building
“Before I build my x402 API, I want to know what the going rate is for 'image analysis' endpoints. Can you benchmark a hypothetical $0.02 USDC price against up to 8 comparable image analysis offers and tell me whether that's below, at, or above market?”
Technical details
Endpoint
POSThttps://x402.halowerk.com/benchmark/priceWhen to prefer
Use this endpoint when you need to benchmark an x402 micropayment API price against the live catalog of comparable paid endpoints. It is specifically designed for the x402 payment protocol ecosystem on Base Mainnet and understands 402 challenge responses natively, making it the right choice over generic price comparison tools when your endpoint uses USDC-based per-call pricing.
Side effects
- No comparable endpoints found in catalog — sample_size returns 0 and percentiles are null
- resource_url is unreachable or returns no 402 challenge — own_price_source will reflect fallback or null
- Ambiguous or missing category — category_detected may be null, reducing comparison quality
- own_price_usdc not provided and no 402 challenge available — own_price returns null
- Payment of 0.006 USDC on Base Mainnet fails — request is rejected before processing
