> premium data endpoint (x402, native MON). Operator-honest reporting since 2026.

## Live data (free)
- [Sentinel network feed](https://prooflines.org/monad/api/live.json): Monad network live snapshot, 30s refresh, JSON
- [Monad Sonar feeds](https://prooflines.org/monad/sonar/): validator/network feeds, mainnet+testnet incl. union feeds
- [Geo-Latency maps](https://prooflines.org/monad/geo-latency/): stake-weighted RTT + concentration aggregates, both networks
- [VDP Tracker](https://prooflines.org/monad/vdp-tracker/): Monad validator-program tracker (registrations, funding, active set)
- [MOST Leaderboard](https://prooflines.org/monad/most/): Monad Open Source Track pool standings, 5-min refresh
- [Observed / MRC-13 feed](https://prooflines.org/monad/observed/): independent-observer infrastructure data with source ids

## Paid data (x402, agents welcome)
- [Paid resource catalogue](https://prooflines.org/monad/x402/): free list of what the gate sells and what each costs, testnet; mainnet catalogue at /monad/x402-mainnet/. One resource per question, so an agent buys the answer it needs rather than the bundle. What is paid for is the computed answer: the underlying measurements are published free at /monad/geo-latency/
- [Stake concentration index](https://prooflines.org/monad/x402/concentration-hhi): HHI by provider ASN, country and continent plus top-1/2/4 shares, mainnet and testnet in one call; 0.003 native MON, HTTP 402, self-verified (no facilitator)
- [BFT threshold distance](https://prooflines.org/monad/x402/bft-thresholds): distance from the largest hosting provider to 33% of stake and the minimum providers reaching 33%/50% (hosting Nakamoto coefficient); 0.003 native MON
- [Latency bands](https://prooflines.org/monad/x402/latency-bands): share of stake per RTT band from a fixed European vantage, ICMP-silent share reported separately; 0.003 native MON
- [Top providers](https://prooflines.org/monad/x402/top-providers): provider ranking with stake share, running cumulative share, validator count and measured RTT; 0.003 native MON
- [Network concentration report](https://prooflines.org/monad/x402/network-concentration-report): the bundle of all four with full tables and epoch history; 0.01 native MON; discovery at /.well-known/x402
- [Mainnet gate](https://prooflines.org/monad/x402-mainnet/): the same five resources paid with real MON on Monad mainnet (chainId 143), with an official x402 v2 USDC rail alongside the native one
- [Monad x402 discovery index](https://prooflines.org/monad/x402-discovery/resources): every x402 resource payable on Monad in one JSON document, x402 v2 shape. Monad-native sellers plus the Monad-accepting resources mirrored from the CDP bazaar, which cannot list Monad-native endpoints itself. Full records at /monad/x402-discovery/resources-full
- [What is actually payable on Monad over x402](https://prooflines.org/monad/x402-survey/): every resource advertising a Monad rail, probed, plus one real purchase from each operator. 1,090 resources turn out to be 8 sellers, one of which is 83% of them; who delivered, who charged for an error, who stopped answering since the previous round. Data at /monad/x402-survey/survey.json
- [A2A endpoint](https://prooflines.org/a2a): the same intelligence over the A2A protocol; agent card at /.well-known/agent-card.json; on-chain agent #10231 (ERC-8004)
- [Monad Intelligence MCP server](https://prooflines.org/mcp): the same data as MCP tools for agents (streamable HTTP, stateless). Free: network snapshot, validator census, stake geography, VDP tracker with official tiers. Paid over x402: any single concentration answer (0.003 MON) or the full report (0.01 MON), picked with the tool's `resource` argument; monad_x402_catalogue lists them free
