Which alternatives to PMXT are open source?

6 of 10: x402, Hyperliquid Python SDK, ERC-8004: Trustless Agents, Agent Payments Protocol (AP2), Flaunch, Agentic Commerce Protocol (ACP). Openness is read from each project's own published license or repository.

Which alternatives run on the same chains as PMXT?

7: x402, Alchemy, Hyperliquid Python SDK, Enso, ERC-8004: Trustless Agents, Agent Payments Protocol (AP2), QuickNode. Chain support is self-declared by each project unless a named check says otherwise on its listing.

Has Sato Hub verified any of these?

Sato Hub reproduced the documented install for 6 of them: x402, Alchemy, Hyperliquid Python SDK, Enso, World AgentKit, Flaunch. Reproducing an install means the documented setup was actually run — it is not a security review, and Sato Hub holds no security assessment of any of these.

How is this list of alternatives built?

It is a rule over live records, not a hand-written list: every listing in PMXT's own category that carries a Sato Score, ordered by the same evidence the rest of the site ranks on — Sato Score tier, whether an endpoint answered our probe, whether a deploy spec exists and was reproduced, a sustained observed record, and chain overlap with PMXT. It is rebuilt from the records, so it changes when they do.

What are the alternatives to PMXT?

Sato Hub lists 10 alternatives to PMXT in the API / SDK category as of 2026-09-13; highest Sato Scores: x402 (86), Alchemy (83), Hyperliquid Python SDK (76); 6 open source; 6 with an install Sato Hub reproduced. Ordered by how open, active and verifiable each one is — not by quality, and no winner is declared.

Rule · Every listing in PMXT’s own category (API / SDK) that carries a Sato Score, ordered by score tier, observed liveness, deploy-spec and reproduced-install evidence, and chain overlap with PMXT.

This page ranks peers on how open, active and verifiable each one is — the same evidence Sato Hub publishes everywhere else. It is not a quality, safety or performance ranking, it declares no winner, and it cannot tell you which of these fits your codebase. A Sato Score is not an audit: none of these has been security-reviewed by Sato Hub, and a listing with no earned verification is self-reported.

“Differs on” is derived from the records — type, chains, openness and deployment — and states a difference, never a preference. ✓ marks an earned state named as what was checked; none of them is a safety claim.
