greyridge-x402-tools
Keyless x402 APIs for AI agents — USDC per call on Base, free preview on every route, no account and no key. Three product lines:
- DeFi & trading market data — decision-tagged, not raw rows: per-pool yield entry verdicts (SUSTAINABLE / DECAYING / OUTLIER / AVOID + risk score), 6-venue OI-weighted perp funding-rate arbitrage (best long/short venue, thin books screened out), and token spot prices with a confidence score. For DeFi, yield-farming and trading agents that need a go/no-go, not just a number.
- Jobs & hiring data — a live, maintained Greenhouse feed with a stateful change-feed, a per-run freshness SLA, and keyless company enrichment. For sourcing, recruiting-ops and hiring-intel agents.
- Agent safety gates —
mcpscan (vet an MCP server for prompt-injection / tool-poisoning before your agent trusts it) and rugcheck / swap-gate (honeypot + pre-trade checks for Base tokens).

DeFi & trading market data — decision-tagged, pay-per-call
Five keyless Python functions. Every call has a free preview, and the data routes return the complete result for your query 3×/IP/day with no wallet; the paid call ($0.001–$0.01 in USDC on Base) is unmetered.
from greyridge_x402 import (

)
# Ranked DeFi pool yields across chains — APY + TVL + risk-adjusted APY + trend
defi_yields(project="aave", limit=10)
# Should an agent enter THIS pool now? SUSTAINABLE | DECAYING | OUTLIER | AVOID
# (APY-decay forecast, outlier/trap + IL/liquidity flags, risk score, cited reasons)
yield_entry_verdict(pool="747c1d2a-c668-4682-b9f9-296708a3dd90")
# 6-venue perp funding (Binance/Bybit/OKX/Hyperliquid/dYdX/Gate) + OI-weighted arb verdict
funding_rates(symbol="BTC")
# Spot USD price + 24h change + confidence score (pycoingecko-compatible get_price alias)
token_prices(["bitcoin", "ethereum"])
yield_entry_verdict is the repeat-payment case: pass a poolId from defi_yields(...) to re-check an open LP every few hours as its APY decays. funding_rates screens thin-book venues out so the CEX/DEX arb is actually executable. These are the proprietary decision on top of the data — the judgement GoPlus / CoinGecko don't ship. Also as a CLI: greyridge-data yields aave · greyridge-data funding BTC · greyridge-data prices bitcoin,ethereum. Want typed framework tool objects instead of plain functions?

Jobs & hiring data — live, maintained, pay-per-call
A normalized hiring feed built on Greenhouse — read from the live board at run time, not resold from a stale database. Priced per call in USDC on Base; every route has a free preview, no account or key.
The incumbent (fantastic-jobs/greenhouse-jobs-api, ~1,000 users) resells a roughly six-month database refreshed twice-hourly, so it cannot authoritatively answer "is this role open right now." This feed reads the board when you call it, and adds three things the resold DB does not ship:
- Stateful change-feed — every run diffs against the previous one:
new | changed | open | closed, plus ghost-job detection (a role still open far past a configurable age threshold, default 60 days — a likely evergreen "ghost" post). No separate "new-only" scraper.
- Per-run freshness SLA — each response is stamped
OK | EMPTY | SCHEMA_DRIFT | DOWN, so an agent knows whether it got live truth or hit a broken adapter, instead of silently consuming stale rows.
- Keyless company enrichment (
includeCompany) — resolved domain, email provider, SaaS/tech stack, and domain age + registrar per board, derived live from DNS/MX/TXT and RDAP. The incumbent's equivalent fields come from a rented third-party key; ours use no paid API, and the domain is authoritative-or-verified (never guessed — null when it can't be confirmed).
Depth on every job: parsed location (city / state / country / remote), canonical employment type and seniority, salary when the posting states one, and a structured requirements block (a maintained skills taxonomy + minimum years + education level) — all parsed from the posting, no enrichment key.
