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
Returns a JSON object with the service host, its listed median USDC price, a market comparison array showing the service's tag category and its percentile rank plus the market median for that tag, and a 30-day change summary indicating how many times prices were raised or lowered.
Example use cases
Vetting a new x402 API cost
“Before I integrate this new data API, can you look up what api.coingecko.com charges per call on x402 and whether that's above or below median for similar services?”
Monitoring competitor pricing shifts
“Has api.tavily.com changed its x402 price in the last 30 days, and what percentile does it sit in compared to other search-tagged services?”
Comparing market rates before building
“I'm deciding between a few x402 data providers — can you pull the listed price and market comparison for api.openai.com so I know if they're pricing fairly?”
Technical details
Endpoint
GEThttps://api.annalist.dev/v1/prices/service?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically check how much an x402 service costs and how it compares to market peers — especially before integrating a new paid API, auditing a supplier's pricing, or monitoring price drift over time. Prefer this over manual inspection when you need structured, signed pricing data with market context rather than just a raw price quote.
Side effects
- Unknown host returns empty or null listing data
- Service not indexed in Annalist returns 404 or empty result
- Malformed URL or host parameter returns validation error
- Service with no tag classification returns empty vs_market array
- Network timeout if the service is slow to respond
