No account, no API key -- possession of valid payment is sufficient. ## Paid endpoints (HTTP 402, USDC on base via x402 -- no account, no API key, no signup) - POST https://agent-exec.45.67.221.128.sslip.io/execute -- run source code to completion in the sandbox. Runtimes: python3, node.

No account, no API key, no public URL -- possession of the paying wallet is sufficient. Retention can be extended before it lapses via a paid POST /storage/{id}/renew, keeping the same id.

Plans: hour $0.0052 (3600s), day $0.0168 (86400s), week $0.0470 (604800s). See "Coordinating with /claim" below. - POST https://agent-exec.45.67.221.128.sslip.io/attest -- pay to have us fetch a URL from OUR vantage point and return a signed, timestamped attestation of what we saw (hash, status, headers) -- never the body. $0.0080 flat.
