Agent & Infrastructure

Parse major.minor.patch from a semver string. Call when you compare agent dependency versions without a full parser. Returns valid, major, minor, patch for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

PyPI package health API: dependency-hygiene facts from the official PyPI JSON API — latest version, upload time, total releases, yank status, declared dependency count, requires-python constraint, license, summary, and weekly downloads (pypistats). Names are PEP 503-normalized (dots/underscores/hyphens equivalent). Use for auditing requirements.txt and pyproject.toml, supply-chain security checks, and version freshness agents. Cached up to 1 hour per package.

Decision procedure for agents and their operators that answers the three questions every auditor asks after an AI agent spends money: who authorized it, what was the ceiling, and who carries the loss when the purchase is wrong. Covers cryptographic proof that an agent, not a human, executed a payment, signing intent with a held Ed25519 key before settlement so future audits can distinguish autonomous execution from manual action. Includes spend-authorization record schema, approval chain

Join URL or filesystem-like path segments without traversal escape — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that alre…

Map a value from one range into another. Call when you rescale agent metrics between UI and model ranges. Returns mapped value for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

Check whether an object has a key. Call when you preflight required fields before paid calls. Returns has boolean and key for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

Map object keys to JSON type names. Call when you audit agent payload shapes before schema checks. Returns types map for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

Count likely personal-data classes without echoing detected values. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

Detect removed OpenAPI paths and methods before an agent deploys a client-breaking change. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.

Live AI-citation check: runs fresh probes against major AI assistants and reports whether a domain is cited for its vertical's buying questions — citation rate per provider, list position, competitors named instead, and whether the domain's agent-card was discovered. Fresh probes per call (not cached). $0.50 per check. Free companion diagnosis: /api/x402/deep-scan.

Counterparty trust verification for agents: before transacting with a domain, verify its trust artifacts — DNSSEC + DNS-AID records, agent-card, live MCP endpoint, published JWKS, OASF record, x402/commerce declarations. Returns a 0-100 trust score with per-artifact evidence. $0.25 per lookup.

Macro economic indicators (inflation, GDP growth, unemployment) for major countries via World Bank API — no API key required.

State of Agent Commerce report data — full structured JSON, one query

x402 endpoint reliability pre-flight: factual service-delivery measurements of a target x402 endpoint before an agent pays it — reachability/uptime rate, valid-402 rate, response latency (p50/p95/p99), last status, and sampled paid delivery verification. Facts only (no trust score, no 'scam' label). Check whether an endpoint is live and delivers before spending on it.

Batch x402 endpoint reliability: factual delivery measurements (uptime, valid-402 rate, latency, last status) for an agent's whole tool list of x402 endpoints in one paid call. Endpoints with no stored history are probed live, so every billed URL returns real facts. Sweep every endpoint you depend on before relying on them. Billed per endpoint, with volume discounts at 10+/50+/100+ URLs. Facts only — not an endorsement or rating.

Python code execution as a service for agents: send code, get stdout/stderr/exit code. Isolated, hard limits. $0.01 USDC x402 Base.

Ensure a string starts with a required prefix without duplication — first-party local utility for agent preflight and proven micro-utils expansion.
