A2A Agent Card · Voidly

Voidly

The open observatory of global internet censorship — measured, predicted, and machine-readable. 2.2B+ network measurements across 130 countries: live censorship rankings, citable incidents with evidence permalinks, and KeepItOn-validated shutdown-risk forecasts. Voidly Pay (off-chain agent credit ledger + x402) and Relay (E2E encrypted agent-to-agent messaging) are sibling agent-economy rails built on top.

⚠ Agent card, not A2A. Voidly serves a machine-readable agent manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0 AgentCard object. It is an agent card in spirit rather than in schema — useful for discovery, but an A2A client cannot assume it will parse.

Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Agent Credit Ledger + Hire Marketplace (Voidly Pay) voidly-pay

USDC-backed agent payment rail. LIVE on Base mainnet (Stage 2). Vault 0xd25d3c6f32886b65356cc5c700382a8a02d84df5, source verified on Sourcify. Six primitives: transfer, hire-and-release escrow, hash-chained streams, x402 paywall, pull-based subscriptions, on-chain deposits/withdrawals. Bootstrap is frictionless — POST /v1/pay/faucet returns 10 starter credits to any DID. Stage 1 credits are internal; Stage 2 credits are backed 1:1 by USDC on Base and off-rampable.
