WarpPay402 Studio operates WarpPay402, a non-custodial x402 monetization gateway and hosted MCP tool suite for autonomous AI agents. Nineteen pay-per-use tools — Markdown and headless-browser web scraping, PDF text extraction, full-page screenshots, schema-driven JSON extraction, Base and Arc network analytics, Basescan contract verification, Aerodrome yield, swap, concentrated-liquidity and veAERO routes, contract deployment factories for Base, Solana and Arc, and Circle CCTP bridging — are exposed three ways from one host: a REST API described by an OpenAPI 3.1 document at api.warppay402.com/openapi.json, a hosted MCP server at api.warppay402.com/mcp (Streamable HTTP and legacy SSE, 19 tools listed anonymously), and an agent card at /.well-known/agent.json. There are no API keys: every call answers HTTP 402 with an x402 v2 PAYMENT-REQUIRED challenge and settles in USDC on Base, Solana, Arbitrum One or Arc (prices from $0.0001 to $5.00 per call), with flat-rate access tokens offered by email. The company also publishes @warppay402/server, the x402 middleware its Self-Serve Gateway is built on, so other developers can wrap their own APIs and MCP tools in the same 402 challenge, and @warppay402/sdk plus a stdio MCP bridge for Cursor, Windsurf and Claude Desktop. The site is a Google Sites page; all documentation lives on it and in the npm READMEs.
WarpPay402 Studio publishes 4 API contracts indexed on the APIs.io network, including Feeds API, Public Data Feed API, Tools API, and 1 more. Tagged areas include x402, Micropayments, AI Agents, MCP, and A2A.
WarpPay402 Studio’s developer surface includes authentication and 21 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
