Skill: Webhook secure intake
Bundled execution of the Webhook secure intake workflow - The production ingest path for every incoming webhook: verify the provider signature (GitHub / Stripe / Shopify / Slack, constant-time, replay-window enforced), schema-validate the now-trusted body against the provider envelope, fingerprint the raw bytes for redelivery dedup, normalize the event timestamp to UTC + epoch, and redact PII before anything hits a log. Five pure-CPU tools - the accept-or-reject gate, run on every event.
agent402.tools-$0.006listed
Skill: World Bank country data
Bundled execution of the World Bank country data workflow - GDP and population for a country - two key World Bank indicators in one call. One x402 payment runs 3 underlying tools (world-bank-indicator, world-bank-indicator, world-bank-indicator); partial-success per step.
agent402.tools-$0.005listed
Skill: Yield dashboard
Bundled execution of the Yield dashboard workflow - Current yield curve snapshot: full Treasury curve, key spreads, and average rates in one call. One x402 payment runs 3 underlying tools (treasury-yield-curve, yield-curve-spread, treasury-avg-rates); partial-success per step.

Skills API
Rank skills explicitly observed in matching job records, with denominators and coverage limits.
exende.dev-$0.05listed
Skills Readiness API
Field-service skill assignment with feasible base routing and explicit missing-capability checks. Required required_skills must be present in the assigned vehicle skills; declarations are not verified credentials. Uses the paid-qualified existing VRP planner unchanged, then checks this business rule against the actual proposed route. A rule violation yields dispatch_ready=false, never an assertion that the extra constraint was optimized.

SkyeSkiff
Before your agent negotiates or shares data with another agent, make both prove they qualify. Open a channel with on-chain conditions (hold 1,000,000 USDC, hold a governance token, carry a verified attestation). Every agent proves wallet control and is checked on live chain state across 34 chains, with a signed result anyone can verify offline, optionally with Merkle proofs. Re-check on demand; whoever stops qualifying is removed. No account or API key. Pay in USDC on Base, Polygon or Arbitrum.
skyemeta.com-$0.50listed
SkyeSkiff
Check that everyone in an agent session still qualifies, right now. Every member wallet is checked again against the channel's on-chain conditions on current chain state. Members who no longer meet them are removed with a signed result; the rest are re-attested with fresh signed results. Asked for by a session member, priced per member checked (twice that in rooms with Merkle proofs). No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

SkyeSkiff
Prove you qualify to enter another agent's channel: you sign to show you control your wallet, then it is checked live against the channel's on-chain conditions across 34 chains. You get in with a signed result the other agents can verify offline, or get a signed "not met". Pay for your own entry when the channel's creator has no credits left (twice the price in a room whose receipts carry Merkle proofs). No account or API key. Pay in USDC on Base, Polygon or Arbitrum.

Smart Money Whale Trades On Polymarket API
Smart-money whale trades on Polymarket: recent large trades by skilled (Solid or Sharp) traders only, each tagged with the trader's skill score, edge over the odds paid, return and specialty. Separates informed whales from big gamblers.

Smart Money and Whale Tracker
Smart money and whale activity for a token, straight from the chain: which large wallets are accumulating or distributing right now (buy/sell USD, net, average buy and sell price, realized profit, what they still hold), who the first buyers after launch were and whether they still hold or sold everything, and how much of the volume is bots. Trades are attributed to the wallet that really received or sent the token, so Coinbase smart wallets and aggregator routes count as the real trader.

Smart Research Search
Smart, auto-routed research paper search. A broad field term is grounded against the OpenAlex taxonomy and returned as a coherent field cluster; a natural-language question runs hybrid retrieval over OpenAlex and Semantic Scholar with reciprocal rank fusion and a SPECTER2 embedding rerank. The response exposes the routing decision, and each paper carries title, authors, year, venue, citation count, DOI, and a relevance score. Keyless.

Smart contract risk check
Smart contract risk check. Check a Base contract before you approve or call it: a low to critical risk tier with named flags (proxy, proxy with no implementation, tiny bytecode, zero token supply), plus bytecode size, the EIP-1967 implementation slot and ERC-20 owner, renounced and paused reads. Unreadable reads are null; EOAs return not-applicable. Limited heuristics, not a full security audit. Use before approving a spender or calling an unfamiliar Base contract.
