198 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Pay-per-Verify: an agent pays $0.01 to verify a post-quantum (ML-DSA-65 / Dilithium-3 or Dilithium-2, NIST FIPS 204; scheme auto-detected by size) signature over a message against a public key. A generic machine-to-machi...
Use when an agent needs base block number. Returns Fetch the current Base mainnet block number from redundant public RPCs and return structured JSON with source and freshness metadata. $0.002.
Official USD/BRL and EUR/BRL exchange rates (PTAX, Central Bank of Brazil).
Compare up to 64 total extracted spans from at most 16 labeled tools against exact code-point slices of supplied source text and declared UTF-8 hashes. Group identical source spans to expose text disagreements. No OCR/PD...
Compare up to 24 public/synthetic feature summaries: mean differences, reference-standardized shifts and variance ratios. Explicitly flags zero reference variance. Counts and variance convention are declared, not verifie...
Compare up to 64 proposed Base-USDC calls with a declared total budget, per-call cap, allowed payees and human-approval requirement. Returns policy mismatches and exact arithmetic totals. Does not authorize, sign or exec...
Inspect a declared dependency graph of up to 64 nodes and 128 edges: exact cycle membership, source-root reachability, and deterministic graph digest. Duplicate edges and dangling references are rejected. Hash declaratio...
Compare bounded room requirements with supplied topology; report unknown and contradictory declarations, not architectural approval.
Classify up to 100 declared measurement intervals against tolerances as pass, fail or hold. Integer millimetres; uncertainty is an absolute interval half-width, not a confidence level. No sensor verification or engineeri...
Check up to 64 workflow steps for duplicate IDs, missing dependencies and cycles. Returns a deterministic topological order only when valid. No scheduling, tool execution, access approval or guarantee that the workflow w...
Check exact quotes at declared code-point offsets and enumerate overlapping exact occurrences in supplied text (first 32 offsets, complete count). Unicode/case/whitespace are not normalized. A matching quote does not est...
Check declared citation coverage of up to 64 claims against bounded source and locator inventories. Reject duplicate IDs and dangling references. Coverage is structural, not proof that a source supports a claim.
사업자등록번호를 넣으면 국세청 기준 사업자 상태(계속·휴업·폐업), 과세유형, 폐업일을 돌려줍니다. 한 번에 최대 100건, 인증키 불필요. Korea business registration status check: given Korean business registration numbers (사...
Trust evidence for any x402 seller origin: is it indexed, does its manifest parse, how many tools does it publish, which chains does it actually advertise, how many settled calls has it been observed receiving on-chain,...
Scores up to 20 product ideas or keywords against live demand: how many tools on the Apify Store already do it, monthly users of the top tools, the leader and its failure rate, tools that gained most users this month, x4...
Confirm a USDC payment actually settled: given a tx hash (and network), returns whether it succeeded and the USDC transfers it contains (from, to, amount). Optionally check it paid a specific address at least a minimum a...
Boolean verdict with reasons: is this address a real factory-issued B20 on Base? Checks the 0xB200 address prefix, ERC-20 readability, and whether the B20 feature set is activated on the registry.
Compare up to eight declared records per version, converting length units and comparing properties, XYZ poses and wrapped yaw against separate length/angle/ratio tolerances. Reports additions, removals, unit changes and...
Phone-number intelligence in one call: validity and E.164 normalization, line type (mobile, fixed line, VOIP, toll free, premium rate), country and region, carrier hint, timezones, and a deterministic 0-100 fraud/KYC ris...
Keyword and autocomplete suggestions for any seed query. Aggregates Wikipedia OpenSearch and DuckDuckGo autocomplete (both public, no auth) into a de-duplicated ranked list — useful for SEO keyword research, content-gap...
Verify one Ed25519 signature over up to 8,000 characters of exact UTF-8 receipt text using a supplied 32-byte public key. Returns cryptographic validity and message hash. Does not establish issuer identity, trusted time,...
Email validation API: verify an email address with syntax check, MX record lookup, SPF/DMARC, disposable and role address detection. Returns a deliverability verdict. No mail sent.
Check declared publication views before release. Compare 2-8 article, registry and API views against canonical URL, content, release and source-set digests; flag stale, withdrawn or substituted views. No live fetch, rele...
Review permission changes before an agent release. Compare two explicit allow-only sets by tool, action and exact resource; report additions, removals and wildcard additions. Does not resolve IAM inheritance or wildcard...
