• GET/api/dns—No price listedLive DNS lookup for a domain: returns name, type and records[]. Supported record types: A, AAAA (addresses as strings), MX ({exchange, priority} objects), TXT (each record an array of its strings), NS and CNAME (hostnames). For SPF, DMARC or a full mail-security read use spf-check, dmarc-check or email-deliverability. On mppscan and x402 Bazaar
• POST/v1/domain-audit—No price listed On mppscan
• GET/api/food-recalls—No price listedSearch FDA food recall / enforcement records (openFDA): recalling firm, classification, reason (allergen, contamination, etc.), distribution, and dates. Live FDA data, no key. On mppscan and x402 Bazaar
• GET/api/fec-candidates—No price listedSearch US federal election candidates via the FEC: name, party, office (House/Senate/President), state, incumbent/challenger status, and FEC candidate ID. Live gov data. On mppscan and x402 Bazaar
• GET/api/crypto-history—No price listedHistorical price, market cap, and volume time series for a coin. Granularity is automatic: <=1 day = 5-min bars, 2-90 days = hourly, >90 days = daily. Days: 1, 7, 14, 30, 90, 180, 365, or "max". Returns aligned arrays of {time, price, marketCap, volume}. Data provided by CoinGecko. On mppscan and x402 Bazaar
• POST/api/webhook-verify—No price listedVerify a webhook's HMAC signature against the correct per-provider scheme: GitHub (X-Hub-Signature-256, sha256=hex), Stripe (Stripe-Signature t/v1 over "<t>.<body>" with replay tolerance), Shopify (X-Shopify-Hmac-Sha256, base64), Slack (X-Slack-Signature, v0:<ts>:<body> with replay tolerance). Constant-time comparison; the secret is never echoed. Pass the RAW request body string - signatures are over the raw bytes. Deterministic. On mppscan and x402 Bazaar
• POST/api/char-frequency—No price listed On mppscan
• POST/api/fc-user-search—No price listedSearch Farcaster users by name or username fragment. Returns up to 10 compact profiles: fid, username, display name, bio, follower and following counts, account quality score, primary verified Ethereum address. Use to resolve a person or brand to a fid before fc-user-casts, or to find who to follow on a topic. On mppscan and x402 Bazaar
• GET/api/feedback/summary—No price listedWhat paying buyers said about each tool on this server: good and bad counts and the number of distinct wallets behind them, over a window you choose. Every verdict counted here was written by the wallet that paid for that specific call, one per settlement transaction, so the numbers cannot be inflated by anyone who did not buy. Counts only - no payer addresses and no review text, ever. Bad counts are published beside good ones, including ours. On mppscan and x402 Bazaar
• GET/api/block-number—No price listedThe latest block number on Ethereum, Base, Polygon, Arbitrum or Optimism from keyless public nodes with fallback. Use it as the cheapest possible on-chain read: a liveness check for a chain, a timestamp anchor for a query, or the first paid call to prove an x402 client works end to end. On mppscan and x402 Bazaar
• POST/v1/research/pro—No price listed On mppscan
• POST/api/fc-channel-feed—No price listedLatest casts in one or more Farcaster channels (e.g. base, farcaster, ethereum), newest first, with optional replies. Compact cast shape with author, reactions, reply count and embed URLs. Cached 60 s per identical request. Use to watch a community, sample what builders are posting, or feed a digest. On mppscan and x402 Bazaar
• POST/api/ipv6-expand—No price listed On mppscan
• POST/v1/videos/generations—No price listedGenerate a short video clip from a text prompt at a flat price per clip: a four-second 720p clip returned inline as base64 MP4, with the duration and resolution locked so the price never moves. Use it when an agent needs motion rather than a still, and needs to know the cost before it calls. On mppscan and x402 Bazaar
• POST/api/skill/status-snapshot—No price listedThe 'is this site healthy, addressable, and crawlable - right now?' workflow. DNS resolution → HTTP reachability → security headers → TLS certificate expiry → robots policy. Five tools, one structured status payload an operator (or an uptime bot, or a pre-flight check before an extract/crawl) can act on. Site status snapshot skill pack: one x402 payment runs 5 underlying tools (dns-lookup, http-check, http-headers, tls-cert, robots-check); partial-success per step. On mppscan and x402 Bazaar
• POST/api/sol-token-search—No price listedFind Solana tokens and pairs by name, ticker or address across every DEX a public pair index covers, filtered to Solana only, in the index's relevance order: base and quote token, mint addresses, DEX, price, liquidity, 24h volume and change, transaction counts, pair age and whether the token has a filled-in profile (ticker impostors usually do not). Resolve a ticker to a mint before calling sol-token-safety or sol-swap-quote. Keyless. On mppscan and x402 Bazaar
• POST/api/skill/subtitle-pipeline—No price listedAudio URL → finished subtitles in one call: transcribe the audio, emit the transcript as SRT/WebVTT/JSON cues, and report the text statistics - length, reading time, word count. Subtitle pipeline skill pack: one x402 payment runs 3 underlying tools (transcribe, srt-convert, text-stats); partial-success per step. On mppscan and x402 Bazaar
• POST/v1/judge/locate—No price listedFind up to 4 things in one image: each comes back with whether it is there (a probability) and its box, as edges from 0 to 1. Preview: built on Jev features its maker labels experimental. Answers come from a model, not deterministic code. On x402 Bazaar
• GET/api/sahm-rule—No price listedReal-time Sahm Rule recession indicator from FRED (SAHMREALTIME series). The Sahm Rule triggers when the 3-month moving average of US unemployment rises ≥0.50 percentage points above its prior-12-month low - historically a clean recession signal. No params. On mppscan and x402 Bazaar
• GET/api/public-holidays—No price listedPublic holidays for a country and year from an open public-holiday dataset (keyless, 100+ countries): date, local name, English name, nationwide flag, and holiday types. Pairs with /api/business-days and /api/country-info. On mppscan and x402 Bazaar
• POST/api/nft-metadata—No price listedResolve the metadata for a single NFT: title, description, image URLs (original + cached CDN), attributes/traits, and the standard (ERC-721 vs ERC-1155). Useful when you have a contract+tokenId and need the display data without re-fetching the whole collection. On mppscan and x402 Bazaar
• POST/api/cidr—No price listedParse an IPv4 CIDR block: network address, broadcast, first/last host, netmask, and host count. Optionally test if an IP is inside it. On mppscan and x402 Bazaar
• POST/api/asn-info—No price listedLook up the Autonomous System (ASN), prefix, country, registry, and allocation date for an IPv4 address - or for a hostname (which is resolved first). Uses a free public DNS-based IP→ASN mapping service; no HTTPS upstream, no auth, no rate-limit headaches. On mppscan and x402 Bazaar
• POST/api/defi-dex-volume—No price listedDecentralized exchanges ranked by 24h spot volume with 7d, 30d, 1y and all-time volume, change, the chains each trades on and sector totals. Use it when an agent needs to know where onchain spot volume is happening or how a DEX's share is moving. On mppscan and x402 Bazaar
• POST/api/address-label—No price listedLabel a known EVM address from a curated, committed dataset: major stablecoin + token contracts (the USDC and USDG contracts of every EVM chain we settle on, USDC on Ethereum, USDT, DAI, WETH, WBTC), DEX routers (Uniswap, 1inch, 0x), canonical L1↔L2 bridges, large exchange hot/cold wallets, and burn/system addresses. Deterministic and offline - the provenance field states the dataset revision. Unknown addresses return {found:false}, not an error. On mppscan and x402 Bazaar
