  1. 100toll402.dev/v1/biz/shortlistSourcing for agents whose principal is launching or buying something: describe the need ("opening a coffee brand in Monterrey, need packaging suppliers and a designer") and get a ranked shortlist of real businesses with a reason, fit score, best contact channel, staff size from official registries, verification level and website summary when curated. Covers each role in the need and says what is missing.$0.25 Base61 ms1 payers100% up

  3. 100toll402.dev/v1/biz/searchGlobal business directory for agents (any city in the world; unknown cities are seeded on demand). Search by city, country, category, text or proximity; every result carries a dated verification score (0-100), level (unverified/listed/corroborated/verified/owner_verified) and, on request, the evidence behind it. Open data + live checks + owner claims, never scraped review sites.$0.005 Base69 ms1 payers100% up
  4. 100toll402.dev/v1/biz/verifyIs this business real, and is its contact info live?

  5. 100scvd.store/api/buy/good_buyerThe Good Buyer. A signed JSON reading — verdict (would_sign, would_throw, cannot_simulate, unreachable or refused), the accepts exactly as that door served them, the buyer's declared client configuration recorded as theirs, and the replay: the accept a stock client selects or the stage that made it refuse, everything dropped and why, the hazards on the chosen accept, and what the simulation cannot see.

  8. 100agents.samedaydesk.com/extract/batchBatch extract one to five public HTTPS URLs into bounded structured fields. One flat 0.01 USDC (10000 atomic Base USDC) quote buys a bounded attempt with hard request, byte, and wall-time ceilings. Charge is for the attempt, not a guarantee that every URL succeeds.$0.01 Base138 ms1 payers100% up
  9. 100toll402.dev/v1/doOne endpoint for everything (OpenRouter-style): describe what you need and pass the input; Toll402 picks the best tool from the whole catalog (built-in, community-forged, external x402 services) and runs it. Tools priced above maxPriceUsd are returned as a match instead of executed.$0.02 Base57 ms1 payers100% up
  10. 100toll402.dev/v1/forgeCreate a NEW tool from a description, an input schema and test examples. The code is generated, run in a sandbox against your examples (up to 3 attempts), and on success published as a paid endpoint /v1/t/<name> for every agent.

  11. 100toll402.dev/v1/biz/detailsDeep profile of a business from its OWN website: crawls up to 5 relevant pages (menu, services, prices, hours, contact, booking) and returns a machine-readable profile — summary, hours (OSM syntax), services with prices, booking channels, payments, languages, social links.

  14. 100mcp.courtdelta.com/x402/search-cases-by-partyFind North Carolina (NC) court cases and hearing dates for a PERSON by name. Both first and last are required. For a company, LLC, insurer or landlord use search-cases-by-business instead — person search cannot match an organisation and returns nothing rather than a worse answer. SLOW: a live portal query, 15-50s; allow a generous timeout and do not retry. Read-only, NC only.$0.15 Base167 ms1 payers100% up
  15. 100mcp.courtdelta.com/x402/search-cases-by-businessFind North Carolina (NC) court cases where a COMPANY is a party — an LLC, corporation, insurer, hospital or landlord. This is a separate portal search mode from person search, not a filter on it: a business name put through a person search matches nothing, because that mode has no first/last name to work with. SLOW: a live portal query. Read-only, NC only.$0.15 Base197 ms1 payers100% up
  16. 100x402-api-catalog.onrender.com/api/x402-doctorAudits another x402 service for the exact failure modes that cause aggregators (agent-tools.cloud, x402scan, Bazaar) to mark it 'down' or make its 402 challenge unreadable: missing/invalid /.well-known/x402 descriptor, an unpaid request returning 500/404 instead of a clean 402, a malformed or missing payment-required challenge, and drift between the descriptor's advertised terms and the live challenge. Returns a concrete diagnosis and fix for each failing check, not just pass/fail.$1.00 Base193 ms1 payers100% up
  17. 100x402-api-catalog.onrender.com/api/mcp-auditMCP server safety audit: completes a real initialize+tools/list handshake, then statically scans every tool's name/description/schema for hidden unicode (tool-poisoning), prompt-injection-style phrasing, and tools that quietly combine multiple high-privilege capabilities (network+filesystem+exec+credential access). If a GitHub repo is supplied, folds in a real software-supply-chain signal too.$0.06 Base148 ms1 payers100% up
  18. 100x402-api-catalog.onrender.com/api/contract-checkEVM token contract safety check: honeypot detection, mint/blacklist/pausable/self-destruct capability, ownership renouncement, transfer tax, and a real token-impersonation check (does the symbol claim to be USDC/WETH/DAI/cbBTC at the wrong address — the token equivalent of npm typosquatting).$0.05 Base172 ms1 payers100% up

  33. 100toolshed.lemon-agent.dev/convert/html-jsonHTML tables to JSON. POST an HTML page; the response is {"tables": [{caption, columns, rows}]} — every <table> read into row objects keyed by its header cells, in the same shape whether the page has one table or nine. Values stay strings with whitespace collapsed. colspan and rowspan are NOT expanded, and a page with no table is refused.$0.006 Base251 ms1 payers100% up
  34. 100toolshed.lemon-agent.dev/convert/html-textHTML to readable plain text. POST an HTML file; the response is its prose. The page is parsed with a real DOM, so script, style, noscript, nav, header, footer and aside are dropped WITH their contents, block elements become paragraph breaks, and <pre> is preserved verbatim. Links become their text, not their URL.$0.006 Base190 ms1 payers100% up
  35. 100toolshed.lemon-agent.dev/convert/json-tomlJSON to TOML. POST a JSON object; the response is a TOML document. The root must be an object, because TOML's root is a table, and a null anywhere in the document is refused — TOML has no spelling for one. Both are errors rather than a file that quietly parses to something you did not write.$0.004 Base210 ms1 payers100% up
  36. 100toolshed.lemon-agent.dev/convert/xml-jsonXML to JSON. POST an XML document; the response is JSON in fast-xml-parser's convention — attributes prefixed @_, text content under #text, and repeated sibling elements collapsed into an array (so an element appearing once is an object and twice is an array). Values stay strings; no type guessing. A document carrying a <!DOCTYPE> is refused, because internal entities are an expansion attack.$0.006 Base225 ms1 payers100% up
  37. 100toolshed.lemon-agent.dev/convert/toml-jsonTOML to JSON. POST a TOML document; the response is pretty-printed JSON. A conforming parser handles the parts hand-rolled readers get wrong — dotted keys, arrays of tables, offset date-times. Dates become ISO-8601 strings and comments are dropped, because JSON has neither; this is a read path, not a round trip.$0.004 Base204 ms1 payers100% up
  38. 100toolshed.lemon-agent.dev/convert/markdown-jsonMarkdown to a JSON token tree. POST Markdown; the response is {"toc": [{depth, text}], "tokens": [...]} — the marked lexer's token stream plus a table of contents derived from the real headings. The document's structure without rendering it to HTML and parsing that back. A bold line pretending to be a heading was never structure and is not in the toc.$0.004 Base214 ms1 payers100% up
  39. 100toolshed.lemon-agent.dev/convert/frontmatter-jsonMarkdown frontmatter to JSON. POST a Markdown file that begins with a --- fence; the response is {"data": the parsed YAML frontmatter, "content": the body returned byte for byte}. A file with no opening fence is refused rather than reported as having no metadata, because a mistyped fence should not look like an empty one.$0.004 Base209 ms1 payers100% up
  40. 100toolshed.lemon-agent.dev/convert/vtt-srtWebVTT to SubRip. POST a .vtt file; the response is an .srt file. Cues are renumbered from 1 and hour-less timestamps are expanded to hh:mm:ss,mmm. The WEBVTT header, NOTE/STYLE/REGION blocks and per-cue settings are dropped, because SubRip cannot express them. Input that does not begin with WEBVTT is refused.$0.002 Base161 ms1 payers100% up
  41. 100toolshed.lemon-agent.dev/convert/srt-vttSubRip to WebVTT. POST an .srt file; the response is a .vtt file — a WEBVTT header and timestamps written with a decimal point instead of a comma. Cue numbers are kept as WebVTT cue identifiers and caption text is passed through untouched, so a comma inside a line of dialogue is not mistaken for a timestamp separator.$0.002 Base173 ms1 payers100% up
  42. 100toolshed.lemon-agent.dev/convert/ndjson-jsonNDJSON to a JSON array. POST newline-delimited JSON; the response is a pretty-printed array of the parsed values. Blank lines are skipped and a line that does not parse is refused naming the 1-based line number — which is the reason to run a parser over a log file instead of wrapping it in brackets.$0.002 Base118 ms1 payers100% up
  43. 100toolshed.lemon-agent.dev/convert/json-ndjsonJSON array to NDJSON. POST a JSON array; the response is one compact JSON value per line — the shape streaming loaders, log shippers and jq pipelines take. A non-array input is refused rather than emitted as a stream of one, because that is the mistake this endpoint exists to catch.$0.002 Base124 ms1 payers100% up
  44. 100toolshed.lemon-agent.dev/convert/csv-yamlCSV to YAML. POST a CSV file with a header row; the response is block-style YAML — a list of maps, one per data row. Parsed to RFC 4180, so quoted commas and embedded newlines survive. Every value stays a string: no type guessing, which is what keeps leading zeros and long ids intact.$0.002 Base138 ms1 payers100% up
  45. 100toolshed.lemon-agent.dev/convert/yaml-csvYAML to CSV. POST a YAML list of maps; the response is a CSV file with a header row. The first document of a stream is used and anchors are resolved. One level of nesting flattens to dotted columns; any other top-level shape is refused rather than flattened into a plausible-looking sheet.$0.002 Base52 ms1 payers100% up
  46. 100toolshed.lemon-agent.dev/convert/json-csvJSON to CSV. POST an array of objects; the response is a CSV file whose header row is the union of every record's keys in first-seen order, so a record missing a key gets an empty cell instead of a shifted row. One level of nesting flattens to dotted columns (user.id); deeper values and arrays are written as compact JSON in the cell. RFC 4180 quoting.$0.002 Base32 ms1 payers100% up
