Agentic gateway

Older “agentic gateway” links map to controlled agent access for 0xArchive market data: route map, auth boundaries, data-quality gates, and a narrow execution surface instead of free-form endpoint guessing. This is not the same as SIWE verification. SIWE verification is for wallet-signature account ownership checks before issuing X-API-Key credentials or browser sessions. An agentic gateway can use API keys, OpenAPI, docs, CLI, MCP Server, Skill, SDKs, REST, or WebSocket depending on the host.

Gateway Layers

Layer	Role	Docs
Route map	Prevent endpoint and namespace guessing	OpenAPI and Venue coverage
Context	Tell the agent how to choose routes and interpret fields	AI clients
Execution surface	Give the host a safe way to call or generate calls	AI interface map
Auth boundary	Keep keys out of prompts and checked-in config	Authentication
Data gate	Stop stale or incomplete data from becoming output	Data quality
Account verification	Use wallet-signature verification only when needed	SIWE verification

Gateway Boundary Checklist

Use this checklist before an agent writes a script, configures a tool, or widens a market-data job.

Boundary	Public rule
Market-data route	Choose the venue family in Venue coverage, then use OpenAPI or the matching REST family for the exact path and parameters.
Credential handling	Put keys in the host environment or secret manager, then send REST requests with `X-API-Key`; do not paste keys into generated source or prompts.
Execution surface	Pick one surface for the first run: REST, CLI, SDK, MCP Server, Skill, WebSocket, or OpenAPI codegen.
First request	Use one route family, one symbol, one small window, and request-ID logging before adding loops, storage, dashboards, or models.
Payment and wallet flows	Use Facilitator for x402 payment infrastructure and SIWE verification for wallet-signature account checks. Neither changes market-data route shape, schemas, or freshness checks.
Stop condition	If venue family, symbol format, credential path, route shape, or data-quality requirement is missing, resolve that before execution.

When To Use This Pattern

Use an agentic gateway pattern when a coding agent, analyst assistant, dashboard builder, or internal automation should fetch market data but should not invent routes, run unlimited loops, or ignore freshness. The gateway is the combination of context, auth, route contract, and bounded execution. This is an integration pattern, not a separate hosted agent product. Use the concrete 0xArchive surfaces above for route context, auth, execution, and data-quality checks.

Implementation Rules

Pin route context

Give the agent OpenAPI plus the page matching the job, such as Venue Coverage, Data Quality, REST, or WebSocket.

Choose one execution surface

Use CLI for terminal jobs, MCP Server for MCP-capable hosts, Skill for reusable workflows, SDKs for application code, or REST for direct HTTP.

Limit the first call

Require one route family, one symbol, one small window, and request-ID logging before widening.

Separate wallet access

Use SIWE verification only when the user explicitly needs wallet-owned account verification.

Next Step

Open AI interface map to choose the surface, then Coding agents for host rules. Use SIWE verification only for wallet-owned account verification workflows.
