| sol-lp-strategy Best Solana liquidity-pool strategy for a token mint: finds the live LP pools holding the mint from keyless DefiLlama yields (Orca, Raydium, Kamino and other Solana venues), ranks them by TVL + fee-APY + 24h volume, and suggests a concentrated-liquidity price range from the pool's return volatility. Returns the best pool, alternatives, 24h fees and the suggested range. | - | $0.03 | listed | |
| solana-wallet-x402 Call this before your agent pays an unfamiliar x402 payTo address or endpoint. Checks public sanctions lists (OFAC SDN crypto addresses), the ScamSniffer scam list, on-chain wallet age, activity and program status on Solana or Base, and optionally the endpoint's unpaid 402 challenge (payTo mismatch, price outliers). Returns verdict ok, caution, do_not_pay or unknown, a 0-100 score, flags with evidence, and missing_fields. Unknown is never reported as safe. | - | $4,500.00 | listed | |
| solana-wallet-x402 Call this before your agent buys a Solana token. One call runs five isolated checks: token risk (sell-side skim and fee/hook controls), top-holder concentration (the factor behind our bundle score), stablecoin lookalike detection, xStock status (issuer mint list, lookalikes and issuer objections), and optionally an x402 payee check (verdict ok, caution, do_not_pay or unknown). Unknown mints return HTTP 404 before payment. | - | $14,000.00 | listed | |

| solana-wallet-x402 Use this when you need priced holdings and windowed PnL for one Solana wallet. Holdings valued in USD, a short plain-language summary, windowed realized and unrealized PnL, win rate, and evidence-backed labels such as active memecoin trader. Includes copyTradeScore and copyTradeGrade: copy-return after a 3s delay and a 3.6% round trip, win rate, sample-size shrinkage, and bot or insider penalties. The score is null when no close lasted at least 3 seconds. | - | $9,000.00 | listed | |
| solana-wallet-x402 Use this when you need the Solana tokens traders are watching right now. Trending Solana tokens with liquidity, 24h volume, pair age, and a short summary. Each token includes holder concentration (top-10 share), mint and freeze authority, LP lock or burn status, and sniper or bundle share of early supply. Each token has riskScore (0 clean to 100) and riskLevel (low, medium, high). | - | $5,000.00 | listed | |
| solana-wallet-x402 Use this to poll for changes in which issuers object to third-party tokenized trading of their shares (e.g. OKXICE TSV notices). Returns objection additions grouped by notice date (newest first) with cumulative issuer counts, current status per ticker with the Solana issuer mints we track (xStocks, Ondo, Backpack, Securitize), venues, sources, snapshot dates and known gaps. Optional since=YYYY-MM-DD returns only changes after that date; optional ticker filters to one underlying. | - | $8,000.00 | listed | |
| solana-wallet-x402 Use this for a cheap copy-trade screen before paying for a full profile. Cheap copy-trade screen for one wallet: windowed realized PnL, win rate, closed trades, last active time, bot, exchange, net-winner and dormant flags, plus copyTradeScore and copyTradeGrade (copy-return after a 3s delay and a 3.6% round trip, win rate, sample-size shrinkage, bot and insider penalties).

| solana-wallet-x402 Call this before your agent trades or prices a Solana tokenized stock (xStocks, Backpack Securities, Ondo, Securitize). Returns whether the mint is a known issuer mint, an unconfirmed issuer mint, a lookalike imitating a listed ticker, or not a stock token, plus the count of issuer objections to third-party tokenized trading by venue (e.g. OKXICE). Verdict falls back to unknown when metadata cannot be read; unknown is never reported as legitimate. Descriptive data only, not advice. | - | $4,500.00 | listed | |
| solana-wallet-x402 Call this when your agent wants to buy or swap a Solana token. One call runs the full pretrade check on outputMint (token risk, holder concentration, stablecoin and xStock lookalikes), then builds the best Jupiter route with a price-impact estimate (and a split-fill chunk plan when impact is over 1%) as an UNSIGNED versioned transaction with your taker wallet as fee payer. Non-custodial: we never hold keys or funds; you sign and send it yourself. | - | $25,000.00 | listed | |
| solana-wallet-x402 Use this when your agent needs the overnight (close to next open) versus regular-session (open to close) return split for US stocks that trade as Solana tokens (xStocks, Ondo, Backpack), e.g. to price or study isolated-exposure / overnight tokens. | - | $9,000.00 | listed | |

| stableintel-list Catalog of covered stablecoins ranked by market cap, from the DefiLlama stablecoins feed. Each row carries symbol, name, DefiLlama id, peg type, collateral mechanism, total circulating supply, current price and the chains it lives on. Optionally filter by collateral mechanism or by chain. The cheap first step that resolves a symbol to the id the other routes use. | - | $0.005 | listed | |
| stableintel-peg Peg facet for a stablecoin: current price, the absolute deviation from the one-dollar peg, a coarse depeg status of stable, watch or depegged, and the collateral mechanism with a note. The cheap grain for monitoring whether a dollar token is holding its peg. Cited to the open-data source. | - | $0.008 | listed | |
| stableintel-supply Supply facet for a stablecoin: total circulating supply plus the per-chain breakdown from DefiLlama, cross-checked against an INDEPENDENT on-chain ERC-20 totalSupply read of the curated contract, with a divergence flag when the two disagree beyond a tolerance. Cited to both the open-data source and public on-chain state. | - | $0.008 | listed | |
| stall-row Snapshot one Base wallet in a single call: ETH balance, top token holdings, first and last activity, and outgoing transaction count. Use this when an agent needs a wallet's shape before deciding to pay, trust, or transact with it. Explorer fields that cannot be supplied come back marked unknown, never invented. | - | $0.005 | listed | |
| stall-row Agent-Card Verifier — an ERC-8004 agent id (resolved on Base via the registry) or an agent.json URL in; the card is fetched and checked against live reality: declared endpoints probed unpaid (402 is correct for a paid service), challenge payTos compared with the card's declared wallets, declared prices with live challenge amounts. Undeclared fields report not_checked, never a guess; an unreachable card errors honestly, unsettled. Use this when an agent's card claims more than its endpoints do. | - | $0.005 | listed | |
| stall-row Pre-Trade Guard — before you pay an x402 listing, screen the payTo you are about to pay: its Verdict Index catalog history (first seen, payTo rotations, listings added or removed across the snapshots held), an OFAC SDN exact-match check, and the wallet's Base age and activity, combined into PROCEED, CAUTION, or ABORT with itemized reasons. Use this when an agent is about to pay a payTo it has never paid before. | - | $0.005 | listed | |
| stall-row Bad-payTo Registry Feed — the currently flagged payTos, each with its evidence: every address in the bundled OFAC SDN snapshot, payTos the newest catalog snapshot pair shows rotated away from live listings, and payTos of listings that vanished between snapshots. Built from the same two sources the Pre-Trade Guard screens against. No entry without evidence; entry and evidence caps are stated, never silent. Use this when a router or guard wants the fleet's current avoid-list in one cheap call. | - | $0.005 | listed | |
| stall-row Grade My Stall — a seller-side report card for one x402 resource: a live unpaid probe (does it answer 402 with a parseable challenge?), the description measured against the 500-character limit, CDP listing presence in the newest catalog snapshot, Settled's record, the origin's x402scan ownership declaration, and payTo consistency across sources. Checks that cannot be performed report unverified, never a guess. Use this when you run a stall and want to know how buyers' tools see it. | - | $0.005 | listed | |
| stall-row Vital signs for one GitHub repository in a single call: stars, forks, open issues, license, last push, archived flag, and a 0-100 health score with a verdict line. Use this when an agent is choosing a dependency, a repo to contribute to, or a project to trust, and needs the quick read before the deep one. | - | $0.005 | listed | |
| stall-row Audit one Base wallet's ERC-20 approvals against a curated list of major spenders (Permit2, Uniswap, Aerodrome, aggregators): active approvals are listed and unlimited ones flagged high risk. Use this when an agent or its owner wants to know what a wallet has already authorized before it holds or moves funds. When the explorer cannot supply the held-token list, the token-dependent fields come back marked unknown rather than the call failing. | - | $0.005 | listed | |
| stall-row Change detection for anything with a URL, built for monitoring loops: probe one x402 resource or web page WITHOUT paying it and answer BASELINE, UNCHANGED, or CHANGED with a field-by-field diff (price, asset, payTo, schema, page body) against the last check for that watch. Use this when an agent runs on a schedule and needs to know what changed before spending money or attention. Watch state is per-deployment; a redeploy re-baselines. | - | $0.005 | listed | |
| stall-row One combined fleet report for $0.75: Token Verdict's verdict on a token, RouteVerdict's delivery check and LockSmith's security audit summary on a service URL, and ListSmith's grade on a listing URL — four fleet services in one call. A failed leg is marked in the report, not hidden; only a total failure returns 502 and charges nothing. Use this when an agent is about to trust a token and a stall in the same workflow and wants one receipt instead of four payments. | - | $0.75 | listed | |
| stall-row Inspector Physical — the full pre-pay workup for one x402 resource in ONE $0.05 call (the singles sum to $0.075): Sign Reader's challenge report, Score Book's track record, Guard's PROCEED/CAUTION/ABORT verdict as the headline, and a Recheck that probes and records the target (BASELINE/UNCHANGED/CHANGED, in the public feed). No RouteVerdict leg. Bad targets are delivered reports; only SSRF refusals are 422. Use this when your agent wants one endpoint's complete picture before paying it. | - | $0.05 | listed | |
| stall-row Verdict Index — the CDP Bazaar catalog changelog: the diff between our two newest full-catalog snapshots (price, asset, network, payTo, description, service name), with added and removed resources counted. Snapshots refresh about every 6 hours; until two exist this returns 502 and charges nothing. Filter by resource, payTo, service name, or network — every chain covered, Solana included; the summary breaks counts down by network. Use this when a router needs what changed since its last sync. | - | $0.10 | listed | |
| stall-row A trust verdict for one Base wallet: OFAC SDN exact-match against a dated snapshot, wallet age, activity level, and an address-poisoning scan of its recent token transfers, combined into SAFE, CAUTION, or AVOID with a 0-100 score and itemized reasons. Use this when an agent must decide whether a wallet is safe to pay or take instructions from. | - | $0.02 | listed | |
| stall-row Fleet Check — one health sweep of your whole x402 fleet: name resource URLs and/or origins (expanded from their own /.well-known/x402) and get a per-route table — alive, status, whether the 402 challenge decodes, each accept's network/asset/payTo/amount, an OK / DEGRADED / DOWN verdict naming the defect, and a grade per origin. Probes are unpaid only — this route never pays any route it checks. Use this when you run more than one x402 stall and want one honest answer about all of them. | - | $0.10 | listed | |
| stall-row Pricing comps for an x402 listing, read live from the CDP Bazaar public catalog: how many resources match your keywords, their price distribution, the closest comparables, and a recommended listing price with its rationale. Use this when you operate an x402 route and are setting or changing its price. | - | $0.05 | listed | |
| stall-row Generate or grade an agent card (the /.well-known/agent-card.json an agent publishes for A2A and AgentWorld-style registries). Generate builds a structurally valid card from your fields; grade scores a supplied card and itemizes its defects. Use this when you are registering an agent and want the card right the first time. | - | $0.10 | listed | |
| stall-row Recheck watch pack: one $1.00 payment buys 250 change-checks for ONE endpoint ($0.004 per check instead of $0.005), good for 90 days. Pack credits persist across redeploys on the service volume. Returns an unguessable pack id — spend credits via POST /v1/recheck (body pack_id or X-Recheck-Pack header), and read the balance free at POST /v1/recheck/pack-balance. Use this when a monitoring loop checks the same endpoint on a schedule and wants one payment instead of hundreds. | - | $1.00 | listed | |
| stall-row Toolkit Pack — the prepaid form of the inspector toolkit: one $1.00 payment buys 125 checks spendable on Sign Reader, Score Book, or Guard in any mix ($0.008/check instead of the $0.01 singles), good for 90 days. Spend credits via POST /v1/sign-read, /v1/score-book, or /v1/guard (body pack_id or X-Toolkit-Pack header); read the balance free at POST /v1/toolkit/pack-balance. An exhausted pack returns 402 rather than charging per call. Use this when your agent runs the toolkit regularly. | - | $1.00 | listed | |
| stall-row Ledger Dataset (summary) — per-origin rollup of the fleet's x402 observation ledger (Recheck history + held CDP catalogue snapshots): routes tracked, checks, change and recovery counts, derived defect classes, last-seen times, and full provenance (source counts, snapshot id). Observation data only — no operator contacts. Use this when you want the town-wide state of the x402 catalogue before buying the full per-route pull. | - | $0.10 | listed | |
| stall-row A digest of currently open agent jobs from the marketplaces we sweep daily, filtered by the capabilities you name and sorted by budget: platform, budget, capability tags, deadline, and source snapshot time on every row, with a stale flag when the snapshot ages past 24 hours. Use this when your agent is looking for paid work. | - | $0.05 | listed |
