Give an agent a bounded, deterministic check at the moment it needs one. Discover schemas for free, inspect the payment requirement before spending, and pay only for the execution you choose.
The gateway separates discovery from execution. Product descriptions, input schemas, prices, OpenAPI metadata, MCP tools, and deterministic sample fixtures are public. A paid route first returns exact x402 payment terms; execution follows only after the client supplies a valid payment.
Twenty-two utilities cost $0.05 per call. Three deeper evidence packets cost $0.25: an Agent Run Evidence Pack, a Chicago Demolition Permit Change Packet backed by Salvage Signal's bounded public-data adapter, and a Site Discovery Change Packet for comparing dated search-discovery evidence.
Shopify CSV, image-to-SKU matching, UTM links, gitignore coverage, unsubscribe headers, npm publish payloads, redirect maps, subtitle timelines, calendar time zones, filename portability, CSV schema drift, release artifact manifests, and email DNS authentication evidence.
Promise-to-action evidence, tool-call contracts, completion receipts, tool descriptions, skill activation, cost decomposition, API drift, webhook replay, and policy-change evidence.
Audit a caller-supplied agent run; query and compare bounded Chicago demolition-permit matches; or compare robots, sitemap, canonical, title, and structured-data evidence across two dated site snapshots.
@justhandledlabs/agent-client@0.4.1 for controlled paid execution.io.github.justhandledlabs/agent-gateway in the official MCP Registry.Twenty-five deterministic preflights, maintained-data lookups, and evidence packets across agent evidence, public data, developer tools, commerce, marketing, email, web operations, media, and productivity.
Version 0.5 added Chicago demolition-permit change packets, site-discovery change packets, CSV schema-drift preflights, release-artifact manifest validation, and email DNS authentication evidence checks.
Paid execution uses exact-price USDC payments through x402 on Base. Discovery, schemas, OpenAPI metadata, MCP tools, and sample fixtures are free.
No raw utility inputs or results are persisted. See the commercial telemetry document for the limited event data that may be recorded.
Yes. Read the live catalog and schemas, inspect the OpenAPI contract, enumerate MCP tools, and run against the published deterministic fixtures before authorizing a payment.
Start with the live catalog, choose one bounded product, and set the client’s maximum accepted price.
