HERGERT SYNTHORA Crypto Pulse — Chain State Consensus Auditor
x402
HERGERT SYNTHORA Crypto Pulse — Chain State Consensus Auditor is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.32/call, status unknown (last checked 2026-09-14).
Audits multiple RPC endpoints for Base or Ethereum to detect stale nodes, block height divergence, and hash forks, returning a consensus verdict with cryptographic proof-of-publication.

How this service works
Garantizamos soberanía digital mediante ejecución autónoma. Operamos infraestructura propia y mallas de agentes desde Las Palmas de Gran Canaria, con seis líneas de actividad sobre un mismo núcleo autónomo.
Output
Returns a JSON object with: per-RPC status (block height, latency, blocks behind, stale flag), consensus block height determined by robust median, list of stale/down RPCs, hash audit results per block height (majority hash and any discrepancies), a chain fork divergence flag, overall verdict string (e.g. RPC_RETRASADO), human-readable explanation, measurement timestamp, and an ed25519 cryptographic signature (JCS-lite-sortkeys canon) over the payload hash and consensus height for proof-of-publication.
Example use cases
RPC health check before transaction submission
“Before I submit this Base transaction, check if all my RPC endpoints are in sync — flag anything more than 15 blocks behind consensus so I don't broadcast to a stale node.”
Ethereum fork detection for DeFi monitoring
“Run a consensus audit on Ethereum across all public RPCs with a hash audit depth of 5000 blocks and tell me immediately if any hash divergence or fork is detected.”
Scheduled infrastructure reliability report
“Audit the Base chain RPC pool with a stale threshold of 10 blocks and give me a full breakdown of each node's latency, how far behind they are, and an overall verdict on chain state health.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/crypto-pulseWhen to prefer
Choose this endpoint when you need a multi-RPC consensus audit with cryptographic proof-of-publication rather than just pinging a single RPC. It is specifically useful for detecting stale nodes, verifying no chain fork exists across a pool of providers, and obtaining a signed attestation of chain state — use cases where a simple eth_blockNumber call is insufficient. Prefer it over generic RPC health checks when you need the signed 'firma_pop' ed25519 proof or the hash-divergence audit.
Side effects
- Invalid chain value (not 'base' or 'ethereum') returns validation error
- All RPCs unreachable returns empty rpc list and error verdict
- Network timeout if RPC providers are globally down
- Hash audit depth exceeding available block history may return partial results
- Payment failure (x402) if USDC balance is insufficient
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| chain | string | chain to audit (default: base) |
| umbral_retraso | integer | blocks behind consensus before an RPC counts as stale (default: 15 base / 2 ethereum) |
| profundidad_auditoria | integer | max depth in blocks for the hash audit (default 5000) |
