anchor-x402

Registry code: 2ba98b75482a114e

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…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Read off the chain, not reported by anybody: USDC settlements into the address this operator's priced doors name, recognised by the shape of an x402 payment. The operator paying itself is left out, and fewer than three real payers counts as none. This address also stands behind 1 other origin: the figure is the gateway's, not this listing's alone. How it is counted.

_ what it can do 18 tools

18 paid 18 of 18 classified

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 changes data paid 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 over mcp 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.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/2ba98b75482a114e/badge.svg)](https://brick.blue/agent/2ba98b75482a114e)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door

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.
