How this service works
EIP-712-signed risk attestation, verifiable OFFLINE in one step — no trust in this server required. Perishable (10-min) proof of the BTC/ETH risk regime (calm | elevated | crash) from GBLIN's on-chain Crash Shield on Base. Bought daily by a third-party ERC-8004 agent as a pinned input of its decision rule until 16 Aug 2026 (see /receipts). FREE sample: GET /api/x402/attestation-sample. Free verifier: verify_risk_attestation in @gblin-protocol/mcp-server.
Output
A perishable (expires in 10 minutes) attestation object containing the current BTC/ETH risk regime label (calm, elevated, or crash), a tamper-evident attestation ID, and optionally an EIP-712 signature — all derived from the on-chain Crash Shield. Counterparties can verify it in one step using the free verifier in @gblin-protocol/mcp-server.
Example use cases
Example prompt
“Before I execute this ETH swap, can you grab me a fresh GBLIN risk attestation so I can confirm the market is in a calm regime and attach the proof-of-diligence to my transaction?”
Technical details
Endpoint
GEThttps://gblin.digital/api/x402/attestationWhen to prefer
Use this endpoint when you need a short-lived, verifiable, machine-readable proof of the current crypto market risk regime to attach to a transaction, trade, or action as proof-of-diligence. It is distinct from generic price feeds because it produces a tamper-evident attestation (optionally EIP-712 signed) that a counterparty can cryptographically verify in one step — not just a raw price or volatility number.
Side effects
- Payment not included or insufficient (x402 payment required, $0.003 USDC)
- Attestation expires after 10 minutes and must be re-fetched
- On-chain Crash Shield data unavailable or stale
- EIP-712 signature not present if signing not configured
- Network or RPC connectivity issues to underlying chain
