How this service works
Signed data for AI agents, paid per call over x402. Hyperliquid crowd state, smart money and liquidations with what historically happened next, plus independent checks of x402 services and MCP servers.
Output
A JSON object containing the category tag, total service count, price distribution statistics (P25, median, P75 in USDC), and optionally a price check object with a plain-language verdict (e.g. 'above the median'), exact percentile ranking, and the queried price.
Example use cases
Competitive pricing check before launch
“I'm about to launch an x402 API in the LLM category at 0.05 USDC per call — can you check if that's above or below the median and tell me what percentile I'd be at?”
Market research on x402 weather services
“How many x402 weather services are out there and what's the typical price range — give me the P25, median, and P75 in USDC.”
Audit agent cost before tool selection
“I'm evaluating x402 search tools for my agent and want to know what the market rate looks like — what's the median price and how many services are in that category?”
Technical details
Endpoint
GEThttps://api.annalist.dev/v1/prices/benchmarks?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to benchmark or validate x402 API pricing against real market data — particularly when deciding how to price your own service, evaluate cost-competitiveness of a tool, or understand the distribution of prices in a specific service category. It is the only known source of aggregated, signed, per-category price statistics for the x402 ecosystem.
Side effects
- Unknown or misspelled tag returns empty or null data
- Price parameter not parseable as a valid USDC decimal causes error
- Missing required query params returns schema validation error
- Payment failure via x402 results in 402 response before data is returned
