Developers Hub · v0.2.8 (REST & MCP)

Put verification directly in the execution path.

SDK, REST API (/api/v1/verify), or native Model Context Protocol server — one call returns a signed trust verdict before your agent acts.

Drop verification into any agent loop.

Inspect agent tool calls and prompt decisions with pre-execution consensus and tamper-proof attestation.

Reviewer Profiles & Quorum

Pre-configured reviewer presets (financial_compliance, cybersecurity_auditor, legal_citation, clinical_safety, general_adversarial) running across independent model nodes with strict consensus scoring.

Zero Data Retention (ZDR)

In-memory ephemeral execution. Pass zero_retention: true or X-EthersFlow-ZDR: true to ensure payloads are never written to disk or used for training.

Cryptographic Receipts

Every response returns an Ed25519-signed verification certificate with SHA-256 payload digest, offline-verifiable via our public keys or standard tooling.

Live API Key Management

B2B API keys (ef_live_...) are cryptographically bound to an authenticated tenant account for rate limit guarantees, quota enforcement, and verifiable audit trails.

Account Required to Provision Live Keys

Sign in with your Google account or work email to generate, inspect, and revoke production API keys with zero retention enforcement.
