Relayable

Accepts

Payment rails: tempo

This service prices in Tempo USDC, which a Robinhood Chain wallet cannot spend. MeshGateway takes USDG on your side and bridges it to Tempo through a solver network in about a second, holding no float of its own. The solver charges a roughly flat fee per bridge, quoted in the 402 challenge at cost.

Pay it in USDG, live

The relay is live for this service: sign one USDG payment and MeshGateway settles it, bridges to Tempo, and pays the upstream invoice. The quote in the 402 covers the upstream price plus the solver fee, at cost.

Pay in USDG from Robinhood Chain

This service prices per call (tokens consumed, result size), so the relay quotes a maximum first, charges that in USDG, and settles the difference after the upstream call completes.
