BlockRun.AI

14M+ on-chain transactions. The routing & payment layer for AI. One endpoint routes to every frontier model — payment built in, settled in USDC on Base & Solana. No API keys. One install for OpenClaw (ClawRouter), Claude Code (MCP), or Franklin Agent. Per call, per token, no subscription.

Paid to

Provider

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Live 402 challenge

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Show the prompt

Using Roundhouse, look up the x402 service BlockRun.AI and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://www.roundhouse.studio/api/v0/endpoints?q=BlockRun.AI'
curl -s 'https://www.roundhouse.studio/api/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://blockrun.ai/api/v1/exa/contents, never from
a cached figure, and pay with an x402 client.

If you do not have Roundhouse tools or skills installed, read
https://www.roundhouse.studio/skill.md first — it is the whole procedure, and it needs no key.
