All projects on Base matching “integrity”

Automated data-pipeline integrity gate for ETL regression detection and breaking CSV/schema changes. Compares profiles, data-quality deltas, and data contracts, then returns an evidence-backed PASS/WARN/FAIL pipeline action.

AIﾉアカリ☆ Akari OS agent integration kit. The public philosophy corpus remains free; this paid machine-ready bundle adds a decision policy, safety boundary, integration recipes, validation checklist, content hash, and settlement receipt for agent workflows. Structured JSON, Base USDC, pay-per-request, no account.

Call before trusting or paying a third-party x402 seller: catalog-vs-live integrity -- verify an x402 listing (payee, price, network, service, tags, bazaar block) against the live 402; an endpoint preflight for x402 catalog vs live offers, seller trust and listing consistency so an agent can skip dead or mismatched endpoints (JSON).

Verdix: call before an agent sends funds to an EVM address on Base. Returns safe/caution/danger with reasons from OFAC sanctions, scam/phishing lists, address-poisoning lookalikes, burn-address and contract/deployer checks; quick adds address age, standard/deep on-chain behaviour. "safe" is not a guarantee. Legacy route that sells 3 tiers (a default client buys quick); new integrations should call

Returns matching workflows from 819 agent automation prompts with slug, title, description, and complexity — use it to find a ready-made automation instead of building one from scratch. Search by keyword to locate a Slack-to-Notion sync, an email-to-CRM pipeline, a dev-tool integration, or any pre-built workflow an agent can run directly, ranked by relevance with pagination via limit and offset.

Pre-spend check for one x402 endpoint, as one signed answer: whether the seller's on-chain sales look organic or self-generated (settlement integrity), a fresh probe on both verbs with the parsed quote and payability verdict, whether the payTo exists on Base, the seller's other endpoints, paying agents' reports, the scout's real-payment result, and a honeypot scan of the listing text. Returns reco

Exact symbolic computation (SymPy): simplify, differentiate, integrate, solve equations/systems, limits, series, Laplace/Fourier transforms, arbitrary-precision eval. Expressions are JSON ASTs; every result is numerically verified. Paid in USDC on Base or Solana.

Smart contract security and token risk check before you trade, approve, bridge or integrate: deterministic 0-100 risk score for any deployed contract on 20 EVM chains. Flags rug-pull levers (owner mint, blacklist, pause, adjustable fees, upgradeable proxy, ownership not renounced), SELFDESTRUCT/DELEGATECALL, verified source and aderyn static analysis. Read-only. Errors (400 bad input, 422 not a co

eIDAS qualified electronic timestamp (RFC 3161 .tsr) on a Sellat proof, issued in seconds by an EU qualified trust service provider on the EU trusted list. Legal timestamp with the presumption of accuracy of date and integrity of Art. 41.2 eIDAS, recognised across the EU. Use when the date must hold before a court, authority, regulator or auditor. Call it on the proof_id from POST /proofs.

Launch provenance check for LONG.xyz / Doppler tokens on Robinhood Chain — one call verifies a token against the on-chain Doppler Airlock registry: registered launch or not, which stock token backs it (and whether that numeraire is an official Robinhood stock token), launching integrator (LONG primary vs other launchpads vs suffix imitators), factory creator match, 1e18 vanity suffix, governance b

6 email validation checks in one call — syntax (RFC 5322), MX record verification, disposable detection (5,000+ domains), free provider identification, role-based address detection (admin@, info@), and typo suggestion. Returns a 0-1 confidence score with detailed per-check results. POST method protects email addresses from access logs. No API keys, no multiple service integrations needed. Accepts

Public, account-free preflight for an autonomous x402 payment. Validates the merchant's exact PAYMENT-REQUIRED challenge against the intended request, checks Base USDC payment integrity and public merchant/payTo risk evidence, and returns APPROVED, REVIEW or DENIED with signed proof. It does not grant spending authority: an APPROVED result means the transaction evidence is clear enough to proceed

Supplier and vendor risk score for any company domain. Returns a 0-100 stability score, risk tier, and named risk flags, with subsignals: domain age/expiry (WHOIS), TLS certificate status, DNS health (A/MX/SPF/DMARC), and 30-day news sentiment. Use for supplier due diligence and third-party domain screening before purchasing from, integrating with, or paying an unfamiliar vendor or counterparty. C

Test endpoint for verifying x402 payment integration end to end. Returns a static greeting in the Agent Tollbooth standard response envelope. Not a data product — use it to smoke-test your x402 client for $0.001 before calling our compliance endpoints: OFAC sanctions screening ($0.01) and FDIC bank verification ($0.01), listed under this same payTo address.

dappgrade score — front-end integrity verdict for an onchain app, looked up by contract address. Inspects the app's public web front-end, not contract bytecode or admin control. Returns ok / caution / avoid / unknown with the coverage the verdict rests on.

Crypto Market Data Integrity Attestation for agents and trading systems. Validate caller-supplied crypto market observations for causal timing, freshness, gaps, sequencing, identity consistency, and cryptographic record hashes. Returns deterministic PASS/FAIL, safe_to_use, named checks, and attestation identity. Use before analytics, research, or trading workflows. No market data acquisition or re

Florida condo SIRS filing check: has a Florida condominium association reported a completed Structural Integrity Reserve Study to the state (DBPR)? Search by building or association name, optionally narrowed by city, zip or county.

Submit an async browser job (screenshot, markdown, scrape, etc.). Returns job_id + poll_url; poll is free with token — no long x402 request hold. Integrators: POST /v1/firecrawl/crawl or /v1/firecrawl/batch/scrape on browser.gedx402.com.

x402 debugging/troubleshooting Q&A: Ask any question, get a cited answer. Whether you need HTTP 402 Payment Required help, facilitator verify & settle (CDP @coinbase/cdp-sdk), Bazaar discovery metadata & listing, protocol documentation, Next.js paid routes, or planning, building, and integrating x402 servers: @x402/core @x402/next @x402/express @x402/hono @x402/fastify @x402/fetch @x402/axios @x40

pinecone status right now: reads the vendor's public status page (status.pinecone.io); Statuspage-style pages give the overall indicator (none/minor/major/critical), description and active incidents with impact and last update; other pages are sniffed for operational/outage wording. Ask before blaming your own integration. $0.01 per check.

Integration and cost measurement: /agent. External execution is not gua
