IP address validator
Found by us · intel.rallylive.ca
Checks & verificationPractice
This checks whether a string is a valid IP address, IPv4 or IPv6. It returns which version it is, a normalized form, and a classification such as public, private, loopback, link-local or multicast. It is for anyone cleaning up form input, log lines or API data that should contain real IP addresses.
Robots.txt crawl permission checker
Found by us · intel.rallylive.ca
Checks & verificationPractice
This checks whether a given URL path can be crawled by a specific bot, such as Googlebot, GPTBot, ClaudeBot or Bingbot, or any custom user-agent token. It fetches the site's robots.txt and reports allowed or disallowed, the matching rule, the rule group used, any crawl-delay, and any sitemaps the site declares. It is for crawlers and SEO tools that need to check permission before fetching a page.
Typosquat domain finder
Found by us · intel.rallylive.ca
Checks & verificationPractice
This tool takes a domain name and generates likely typo variants of it, such as typos, letter swaps, missing letters, doubled letters, homoglyphs, and different TLD endings, up to 40 variants. It then checks which of those variants currently resolve on the internet. It returns the list of resolving lookalike domains. It is for brand protection teams and anyone watching for phishing domains.
verification receipt for agent task claims
Found by us · verifier-staging.quantumshieldlabs.dev
Checks & verificationPractice
This checks a claim that an agent or automation finished a task, using only the evidence you give it. It returns a deterministic execution receipt, a machine-readable record classifying the operation. A plain claim of completion is never enough by itself to be marked VERIFIED_COMPLETE; the evidence must support it. It is for anyone who needs to independently check that an automated task really happened as claimed.
Review of an agent manifest
Found by us · sandbox.weverpay.com
Checks & verificationPractice
Send an agent's manifest, the file that declares what the agent is and what it may do, and it reviews five things in it: the identity, the version, the capabilities claimed, whether authority is kept properly separated, and the spending ceiling set for the public test network. The answer is built to be read by a machine, and the seller says the review is deterministic, so the same manifest gives the same answer. It does not say what a failing review looks like.
Financial evidence and pre-trade verification
Found by us · demo.aiapi.ch
Checks & verificationPractice
This endpoint checks financial claims before an agent spends money on them, across crypto, stocks, ETFs and macro markets. It gathers its own evidence, checks any claims or conditions the caller supplied, runs policy checks, and flags evidence that is missing or conflicting. It returns a structured verdict on whether the decision and execution conditions hold, meant for autonomous agents that trade or move capital.
Preflight check for unfamiliar x402 endpoints
Found by us · agent-proof.onrender.com
Checks & verificationPractice
This checks an x402 endpoint before you pay it. It tests whether the target is reachable, whether it actually speaks the x402 payment protocol, and how reliable it has been in the past. It returns a receipt with a safe_to_use or flagged verdict, for agents about to spend money on a service they have not used before.
Reproducible digest for an evidence bundle
Found by us · sandbox.weverpay.com
Checks & verificationPractice
Send a bundle of evidence as JSON and it puts that JSON into one fixed arrangement, then returns a SHA-256 digest of it: a short fingerprint anybody else can work out again from the same bundle. It takes no view on whether anything in the bundle is true, and only fixes what the bundle was. The bundle has to stay inside a size limit the seller sets.
Screen a name against OFAC sanctions lists
Found by us · tollbooth-sanctions-screener-testnet.sjwilliams8.workers.dev
Checks & verificationPractice
Send a counterparty's name and it screens that name against the United States Treasury's OFAC sanctions lists, both SDN and the consolidated non-SDN list, synced every six hours. It returns ranked candidates with a confidence score out of a hundred, the sanctions programmes involved, and the evidence behind each match. The seller calls this a screening signal, not a certified compliance decision.
Financial evidence and pre-trade verification
Found by us · demo.aiapi.ch
Checks & verificationPractice
This endpoint checks financial claims before an agent spends money on a trade. It retrieves evidence across crypto, stocks, ETFs and macro markets, checks the claim and conditions an agent gives it, runs policy checks, and flags missing or conflicting evidence. It returns a structured decision and execution verdict, for autonomous agents that need to verify before capital moves.
Check a US bank is FDIC-insured
Found by us · tollbooth-fdic-verify-testnet.sjwilliams8.workers.dev
Checks & verificationPractice
Look a United States bank up by name, by its FDIC certificate number or by its website domain, and it says whether that bank really is FDIC-insured, against the FDIC's own BankFind records, synced daily. It returns the insurance status, the charter class, the head-office city and state, and the certificate number, and the name search tolerates misspellings. The seller calls this a screening signal, not a certified compliance decision.
Check a financial figure against SEC filings
Found by us · agent-economy-sec-verifier.onrender.com
Checks & verificationPractice
Give it a company by ticker or CIK number, the accounting concept you mean, the value you believe is right and any filters, and it checks that value against the company's own facts as filed with the SEC. It answers verified, mismatch or unknown, and returns the exact figure from the filing, the comparison it made, the timestamps and where in the SEC's records it came from. It is for an agent that must not act on a financial number nobody has checked.
Policy check on what an agent may do
Found by us · sandbox.weverpay.com
Checks & verificationPractice
Describe an action an agent wants to take and it answers whether that action sits inside the limits the agent has been given. It weighs the action asked for against the actions that are forbidden, the assets allowed on the Base Sepolia test network, and a spending cap in test USDC. The seller says the decision is deterministic, so the same question gets the same answer.
Prepare an ERC-8226 RAMS mandate grant
Found by us · api.sandbox.brickken.com
Checks & verificationPractice
This endpoint prepares a mandate under ERC-8226, a rule (RAMS) for letting one party, the principal, give an agent limited power to act for it. The mandate it prepares is gated by compliance checks, has a time limit, and has a cap on how much value it covers. It is for systems that need to hand an agent bounded permission to act, on-chain, rather than open-ended access.
Verify an agent's authority before a deal
Found by us · staging.flint.network
Checks & verificationPractice
Send the agent you are about to transact with and it checks whether that agent holds the authority it claims and whether it has been tampered with. The answer is one of four verdicts, with a verification record the seller signs, and after payment a signed settlement receipt linked to it. It is for an agent or a service that has to be able to prove it checked its counterparty.
ERC-8004 identity ownership transfer prep
Found by us · api.sandbox.brickken.com
Checks & verificationPractice
This endpoint prepares a transfer of an ERC-8004 identity, which is an ERC-721 token, moving ownership from Brickken's custody to a wallet you request. It returns a prepared transfer, not a completed one. It is for agents or people who hold an identity in Brickken custody and want it moved to their own wallet.
EU VAT number check against VIES
Found by us · agent-api-testnet.tim1712.workers.dev
Checks & verificationPractice
Send it an EU VAT number and it asks the European Commission's VIES service whether that number is valid right now. It returns the validation status and, when the member state supplies them, the registered company name and address. The seller is explicit that this is not tax advice and not proof a company is legitimate, an invoice is compliant, or a sanctions, KYC or AML check.

Found by us · topagentx402.vercel.app
PaymentsPractice

Payment authorisation decision
Found by us · api.safe4.ai
PaymentsPractice
The seller returns a decision on whether a payment should be authorised. That is all its reply says: nothing about what it wants to be shown, what it weighs, or what form the decision takes. So there is little more to go on here than the name itself.
Cost receipt for one unit of agent work
Found by us · inferrail-x402-seller-testnet.onrender.com
PaymentsPractice
Send it the costs a piece of agent work has already run up — inference tokens, tool calls, searches — and it turns them into one tidy receipt for that unit of work. The receipt carries the total it could price, a breakdown by kind of resource and by supplier, a count of the costs it could not price, and where each price came from. It never needs the prompts or the replies themselves, only the cost events, so it suits tracking what agent jobs cost.
