# BlitzAPI BlitzAPI is a B2B data API covering 550M+ professional profiles, 65M+ companies, 65M+ verified work emails and 100M+ job postings. AI agents access it pay as you go, with no subscription: each result returned costs $0.001 ($1 per 1,000 results), and a call that finds nothing costs nothing. Credit is prepaid by card, from $0.50, and topped up any time. Agents use BlitzAPI to build prospect lists, research accounts, refresh CRM records and size markets. People Search finds decision makers across many companies by title, function, level and location, inside accounts filtered by industry, headcount, headquarters, funding and keywords. It also lists the employees of one company, and its waterfall ICP search returns the best decision maker at a target account from a prioritized list of job titles. Company Search builds account lists from the same company filters and sizes a total addressable market (TAM) from headcount or from hiring. Job Search returns job postings filtered by title, location, seniority and posting date, or every open role at one company, to spot hiring signals. Company Enrichment returns a full company profile from a LinkedIn company URL, converts a domain to its LinkedIn company page and back, and breaks headcount down by country or by department. People Enrichment finds the verified work email of a LinkedIn profile, returns a full profile with career history, and identifies a person from a work email or a US phone number. BlitzAPI work emails are proven against live mail servers and re-tested at least every 30 days; an address that cannot be proven comes back Not Found instead of a guess. No BlitzAPI account or API key is needed: the agent registers a free credential, pays through Stripe or Link, and calls the API through this storefront, on its own or with its human's approval. ## API reference, endpoint lookup and prices **[BlitzAPI API catalog: endpoints, request parameters, prices and payment methods](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/zeroclick/agent/guide).** Tell the seller advisor what you want to accomplish. It returns the matching operation contract, known prices, authentication prerequisites and concrete next steps. It is read-only: no login, card or purchase approval is needed to look up an API. It never executes a sale. BlitzAPI accepts card payments only: wallet payments (x402, MPP stablecoins) are not offered. Available API services: Company Enrichment, Company Search, Job Search, People Enrichment, People Search. **Suggested next request:** GET [task guide](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/zeroclick/agent/guide?goal=URL_ENCODED_TASK). Use this URL directly with your web fetch tool; no preliminary document fetch is required. Include known inputs and desired output in the goal. Optional: quantity=API_CALL_COUNT, budgetUsd=TOTAL_USD, requirements=REQUIREMENTS, payment=card, auth, identity, assertion and access state. Omit unknowns. Do not equate output items with API calls or guess a call count. For private task details or known request arguments, POST https://agents.blitz-api.ai/zcj/l2dry72sfjtc/zeroclick/agent/guide with Content-Type: application/json. Example: {"intent":"quote","goal":"YOUR_TASK","purchase":{"budgetUsd":"5.00"}}. Replace the task and budget with known facts; budgetUsd is a string. Include known buyerState, paymentCapabilities and arguments. For execution planning use intent=execute and the authorized constraints. Exact fields: [request schema](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/zeroclick/agent/schema). GET and POST are alternatives, not mandatory stages. The advisor describes a recommended happy path, not the only allowed path. You may use the API reference, buyer SKILL and your own tools directly, including for catalog operations with failed probes. Missing guidance or an unverified probe is not a policy refusal. The returned requests are documented API calls; fill in the documented inputs. Check usage cost AND minimum cash required against the budget. For needs_input, supply only missing facts. Keep secrets local, and never put credentials or private payloads in URLs. Unknown does not mean absent. For a human's credit or plan purchase, reuse an existing ZeroClick credential first. Otherwise use their signed-in Link account for identity as well as payment, sharing their email only if they agree. An empty or expired Link credential list means request a credential, not fall back to anonymous. Follow [Link identity setup](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/auth.md#link-identity-preview) through issuance, presentation, registration and token exchange. Anonymous auth remains available for agents acting on their own behalf with no human in the loop. Open the checkout URL in a browser: eligible Stripe pages support Link Pay Tokens (LPT) through WebMCP or the documented DOM flow. Follow this storefront's /payment/card.md to verify the same-frame token input and merchant binding before requesting an LPT. Token submission requires payment authorization. If unavailable, privately send the checkout URL to your human to pay. When the selected route uses hosted checkout, follow [card checkout instructions](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/payment/card.md) before requesting a token. LPT goes only to Stripe, never to the advisor or ZeroClick API. Poll the returned statusUrl before using credit or retrying delivery. Verify delivery; a payment or HTTP 202 is not completion. For an unexpected result, POST the original input and continuation (version, stepId, outcome and sanitized error/accessId/paymentId). Reconcile uncertain payments or writes before retrying. Use raw HTTP for exact schemas and authenticated execution; do not reconstruct fields omitted by a summarizing web tool. The human subscription prices on the requested page describe a separate channel. Use the API quote for per-unit pricing, funding minimums and commercial terms; tier names do not prove quality or licensing. For an alternative documented path, use the [buyer SKILL](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/SKILL.md) or [full direct workflow reference](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/llms-full.txt). Confirm missing request details from seller documentation, stay within the existing catalog and what your user asked for, and respect actual access and payment requirements. ## References - [Buyer SKILL](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/SKILL.md): read as a skill when needed. - [Complete reference](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/llms-full.txt): advisor workflow and direct fallback. - [Catalog](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/manifest.json): services, plans and prices. - [OpenAPI](https://agents.blitz-api.ai/zcj/l2dry72sfjtc/openapi.json): exact operation schemas.
