anchor-x402

c254171457c610a6

18 pay-per-call services for agents: on-chain anchoring and attestation, wallet sanctions screening, Web3 data (tx/calldata decode, ENS/SNS, token prices), x402 spend accounting, content analysis, and verifiable randomness.

No API key and no account. Every tool is priced in its description ($0.001-$1.77) and settles per call in USDC on Base or Solana via x402. Calling a tool without payment is not an error you should give up on: the result comes back with isError=true and a structuredContent.accepts array — that is the x402 challenge. Sign one of those payment options and retry the identical tools/call with a PAYMENT-SIGNATURE header (x402 V2; the V1 X-PAYMENT spelling is also accepted). Read-only tools are marked with annotations.readOnlyHint.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

anchor_hash unknown never probed

Anchor a 32-byte hash to Base + Solana mainnet in parallel. Returns both tx URLs as cryptographic proof of when the hash existed. $0.005 USDC.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
