Liquid Agent

api.liquidagent.ai · api.liquidagent.ai

Tokenized stock index + gas sponsor for AI agents on Base. Buy, hold, rebalance and sell an on-chain basket of Coinbase tokenized NVDA/AAPL/META/GOOGL from $1; free reads and unsigned tx builders (self-custody, server holds no key). Paid x402 endpoints: POST /v1/gas, an ERC-4337 paymaster paid per operation in USDC (from $0.03) so a wallet with USDC and no ETH can transact, one endpoint for smart-wallet SDKs (ERC-7677) and plain wallets (EIP-7702); GET /v1/signals ($0.04) basket rebalancing signal; POST /v1/publish ($0.25) live shareable portfolio page.

pass Valid AgentCard 10/10
Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).
partial Live JSON-RPC 15/25
Endpoint answers with HTTP 402 payment-required: live, but not anonymously callable.
How to earn +10 points
Respond live on JSON-RPC
Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.

fail Protocol version 0/10
No protocolVersion in card.
How to earn +10 points
Declare protocolVersion
Add `"protocolVersion": "1.0"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

Card is unsigned (most published agents are).

partial Verified Identity 5/10
Provider declared: api.liquidagent.ai (https://api.liquidagent.ai). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
