api record

Read live terms. Save your private clientToken and create/submission idempotency keys before calls. Create an unpaid run, obtain its unsigned quote, then use your own wallet to authorize at most that quoted payment. enroll submits only your supplied x402 signature. A 202 or timeout is unknown/pending: poll the same run and receipt, never assume failure or create a replacement payment. Only finalized chain evidence proves reward/refund. MCP access proves transport use; it does not prove Registry discovery or autonomous provenance.

_ 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.

_ what it can do 7 tools
1 paid1 open 5 never probed 2 of 7 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.

  • enroll 2 USDC paid never probed

    Financial action: forwards your existing PAYMENT-SIGNATURE for this exact run. Does not sign, fund a wallet or create a new authorization. Poll the same run after pending/unknown outcomes.

_ 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.

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
0

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