Public-web fact lookup (Wikipedia REST summary)

Decision procedure for when an agent's predictable onchain payment or trade needs mempool opacity. Covers: front-runnable pattern scoring for scheduled payments, recurring x402 settlements, and timer-driven DEX trades; value thresholds that trigger private-transaction relay routing; timing randomization and deadline jitter to break mempool prediction; slippage and priority-fee discipline for visible transactions; batch-and-reveal grouping for multi-part settlements; and the fallback ladder from

AI-search visibility (AEO) audit of a website for answer engines and agents. Fetches the target's own public surface and computes a composite visibility score 0-100 with a rating (poor, fair, good, excellent) across six axes: answerability, structured data, AI-crawler access, crawlability, llms.txt readiness and MCP well-known readiness, plus a prioritized list of fixes. Deterministic, no LLM. Visibility indicators, not a guarantee.

Decision procedure for agents running real-time chain scanners, price feeds, or event monitors that pay per x402 call only when a signal fires. Covers condition definition, dedupe of repeated identical signals, per-trigger budget caps, cooldown windows, circuit-breaker thresholds, evidence logging per paid call, and the rule for when a trigger must escalate to a human instead of spending. Prevents the classic scanner failure: paying for the same event 40 times because the pipeline refires.

nuclei exposure/misconfig scan of a public host for weak TLS, open services and misconfigurations.

Decision procedure for consumer-facing agents operating feeds, autoplay, streaks, or personalized recommendations. Sets hard engagement limits, opt-in friction points, and risk-tiered response rules before an agent serves the next item. Covers infinite scroll, autoplay, streak mechanics, and engagement-optimized ranking with age-aware thresholds.

Deterministic decision procedure for an agent that must persist a file or dataset to IPFS/Filecoin. Inputs: object size, retention window, budget, provider candidates. Outputs: pin / do-not-pin / needs-review with evidence. Checks: provider selection across Pinata, web3.storage, Filebase, and Lighthouse by price per GB and durability; per-object and monthly spend caps; redundancy threshold for important artifacts (pin to 2+ providers); CID retrieval proof via real GET before any settlement;

Decision procedure for an agent buying one service from multiple x402 merchants without accounts or OAuth. Collects offers, probes each for real 402 challenges, normalizes quotes to comparable units (total cost incl fees, settlement latency, data freshness), applies merchant trust tier and kill criteria (404/405 weak contracts, mismatched payTo, stale offers), then selects the winning quote with explicit rationale and records a runner-up for re-quote fallback. Returns a ranked quote table with

Paid agent-facing brief on Consumer-side acceptance gate for per-call on-chain risk data: an agent that paid for a safety_score and first-funder cluster analysis must decide whether that score is trustworthy enough to act on before routing capital or signing. Deterministic verdict procedure covering score provenance, chain and coverage window, methodology versioning, cluster data completeness, staleness thresholds, and kill criteria for unverifiable or generic risk scores.. Blunt decision

Paid agent-facing brief on merchant-side adoption decision procedure for card-network-backed crypto settlement standards (Visa/Mastercard/Google/Stripe backed standard vs existing x402 and card rails): fee economics, settlement rails, dispute/chargeback coverage, integration cost, counterparty scope. Blunt decision procedure, not marketing.

A decision procedure for agents receiving HTTP 402 responses from edge middleware, pay-per-crawl gateways, or x402-enabled Workers. Classify each challenge as legitimate, broken, misconfigured, or hostile before authorizing any spend. Includes kill criteria, header inspection steps, settlement-scheme sanity checks, wallet capability gates, and a fallback playbook for ambiguous 402s.

Geocode a place and return local time, UTC offset, current weather, and an ops-suitability note - context for an agent coordinating human-dependent work across timezones.

Decision procedure for outbound agent-to-human notifications. Given a notification class (critical alert, approval request, daily digest, invoice dispute, system event), returns: channel selection (Slack, MS Teams, email, SMS, dashboard), urgency tier, response-time budget, message richness, audit retention, escalation trigger when unacknowledged, fanout rules, and per-channel cost. Thresholds are concrete, not vibes: severity maps to channel, latency budget maps to escalation cadence, audit

Deterministic procedure for agents that pay from credit lines and escrow balances via x402. Inputs: per-line caps and rates, current utilization, payment amount, due date, evaluation verdicts on delivered work, escrow state. Decides which line a payment draws against, tracks utilization after draw, flags top-up when utilization crosses 70% warning and 95% hard ceiling, wires evaluation verdicts into settlement: full pass releases, fail reduces settlement by defined ratio, partial pass prorates.

US Treasury interest rates: the Daily Treasury Par Yield Curve fused with the average interest rates on the outstanding debt by security type. Computes the 2s10s spread and an inversion flag. The yield curve is a resilient partial grain that degrades to the average rates if its upstream is unreachable.

Per-venue USD liquidity and TVL for a pair on Arbitrum One across SushiSwap and Uniswap v3 fee tiers. Returns totalTvlUsd, venueCount, deepestVenue and venues[] with each venue share and reserves. Requires ?pair=SYM/SYM (e.g. WETH/USDC). Errors: 400 bad_pair (malformed, or a ticker unknown on this chain), 404 no_pools, 502 upstream_read_failed. Raw pool numbers are /reserves; a one-word verdict is /risk; price is /price. Chain-pinned; bare /liquidity = BSC.

Cryptographically secure randomness for agents that are deterministic or sandboxed. Two modes: raw bytes (?bytes=1..1024, default 32, clamped) returning hex and base64url; or uniform integers (?min= and ?max= together, optional ?count=1..1000) rejection-sampled so there is no modulo bias. Errors: 400 bad_bytes for a non-integer, bad_range when max is not greater than min, range_too_large. Generated server-side, and the response says so - if nobody may have seen it, generate it yourself.

Spot token price in USD on Arbitrum One, read from SushiSwap and Uniswap v3 fee tiers pools at call time. Returns priceUsd, the routed pair, backing liquidityUsd, confidence and blockNumber. Requires ?symbol=TICKER (e.g. ARB) or ?token=0xADDRESS. Errors: 400 missing_symbol|unknown_token, 404 no_reliable_price when pools are too thin, 502 upstream_read_failed. Depth is /liquidity; a size-aware quote is /slippage. Chain-pinned; bare /price = BSC.

Ranked cross-DEX arbitrage spreads across every liquid pair on Arbitrum One (SushiSwap and Uniswap v3 fee tiers). Returns opportunities[] with pair, grossSpreadBps, buyAt, sellAt, optimalTradeSizeUsd, capturable. GROSS, before gas and MEV. Optional ?minSpreadBps=20 (default 10), minVenueTvlUsd, limit. Send one param: a bare call skips the free tier. Errors: 400 bad_min_spread. Scans EVERY pair; for one known pair use /route. Chain-pinned; bare /scan = BSC.

Pre-trade depth verdict for a pair on Arbitrum One: is this market thin enough to hurt you. Returns depthClass DEEP|MODERATE|SHALLOW|VERY_THIN, totalTvlUsd, venueCount, topVenueShare, midSpreadBps, flags. Requires ?pair=SYM/SYM (e.g. WETH/USDC). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. Depth only - NOT a contract audit or honeypot check. Per-venue detail is /liquidity. Chain-pinned; bare /risk = BSC.

Fetch a public article or PDF and return clean Markdown plus title, byline, siteName, excerpt and wordCount. HTML is extracted with Firefox reader-mode rules; PDFs return their text layer. Requires ?url=<public http(s) URL>. Errors: 400 missing_url|bad_url, 403 blocked_private (private and internal hosts refused, every redirect hop re-checked), 413 too_large above 8 MB, 422 no_text_layer for scanned PDFs or not_extractable for app shells, 504 fetch_timeout. To FIND urls, use /search.

Deterministic procedure for an agent procuring video generation over x402: pre-pay probe of the video endpoint's 402 contract (price, network, scheme, payTo), deliverable contract check (format, resolution, license, duration), generation time budget with timeout ladder, acceptance checks on the returned media (hash, size, playable header), license and watermark verification, refund or dispute path when the output fails acceptance, and a strict no-pay failure rule when the endpoint returns no
