Read-only Bitcoin and Ethereum mainnet RPC for AI agents: seven Bitcoin methods and 37 Ethereum methods covering balances, blocks, transactions, receipts, logs, proofs and simulations. One POST endpoint per network; JSON-RPC method and params in the body. Payments currently use test USDC on Base Sepolia through Coinbase CDP, at 0.0025–0.01 per call. Historical Ethereum state is subject to node retention; archive state is not guaranteed.

D
Conformance score: 48/100
Catalogue listing, not an A2A agent: a paid API listed by agentic.market. Scored on the 3 criteria that apply (19 of 40 points, scaled to 100); the A2A card criteria do not apply.

n/a Agent card n/a
Not applicable: a paid API listed by agentic.market. The host serves no A2A agent card at /.well-known/agent-card.json, so the card criteria are not scored.
partial Live endpoint 10/25
The host publishes a payment manifest; we have not yet observed a live 402 challenge.
n/a Protocol version n/a
Not applicable: no A2A agent card served.
n/a JWS signature n/a
Not applicable: no A2A agent card served.
n/a Uptime track record n/a
Not applicable: our probes looked for an A2A agent card, which this host does not serve. That says nothing about the API's availability, so it is not graded.
n/a Skill declaration n/a
Not applicable: no A2A agent card served.
partial Verified Identity 5/10
Provider declared: api.block402.xyz (https://api.block402.xyz). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
