Registry code: d02804508e7520f3

411data is a lead and business-data enrichment API. MCP tools mirror the REST surface — enrichment lookups and lead search are paid; account tools are free with a bearer token. Billing: every paid call first debits virtual USD balance (~$0.20 starting credit at wallet mint via /connect). When balance is exhausted, calls return 402 with an x402 envelope for wallet USDC settlement on Base. Bill-on-match routes refund the charge when no usable match is found. 402 responses include billing_reason, virtual_balance_usd, connect_url, topup_url, and llm_user_message — read those fields and tell the…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

enrich_person unknown never probed

PAID ($0.500): Person search: find phones (including mobile), emails, and addresses by name, reverse phone, or address. Use for residential/person leads. Bill-on-match. Use when: Residential or person-shaped lead — find phones, emails, and addresses.

submit_enrich_job unknown never probed

Queue async enrich routes (websearch, lead-session, slot-rerun, slot-person, slots-rerun, synthesize-patch, finding-rerun, sic-rerun) with deferred billing. With bearer: pre-charges bill_up_to_usd from virtual USD (route catalog default when omitted; max $50) → 202 + poll_bearer (billing_mode virtual_balance). Without sufficient balance / anonymous: not supported via MCP (use REST + CDP upto). Poll with get_enrich_job. Recipe: /cookbook/async_enrich_jobs.

enrich_lead_session unknown never probed

PAID ($1.500): Enrich leads with deep research: paste a CRM record as JSON in lead (one export row or [{…}] array). Finds decision makers and their contact information via directory phone/people hunt, research_web fallback, company pass. Returns summary_markdown (user-facing cited summary — show to the user with links intact) + lead_enrichment_v1 backfill JSON. Auto-persists to the audit store when phones or contacts are found (see persist block). Bill-on-match when no usable fields found. Same lead (company+address, or CRM contact_id when supplied) in a new session warm-seeds from this agent's latest persisted backfill (skips completed tools) unless refresh=true. Follow-ups: same bound lead (keep contact_id; never swap in discovered legal entity names) + prompts: [user follow-up]. refresh=true only for explicit scratch re-hunts. See cookbook lead_session_followups. Use when: Deep research on a CRM record to find decision makers and their contact information.

Use instead of refresh:true full session when the user names a single slot. model_id accepts public ids (data411-hunt-forge) or provider slugs (x-ai/grok-build-0.1).

export_profile_save_version unknown never probed

FREE with bearer — publish a new immutable version of an export profile's columns, instructions, settings, and mapper model (201). Column set, hints, instructions, and model form the mapping_hash that makes re-exports free; column order and CSV output settings are excluded, so reordering costs nothing.

export_stock_columns unknown never probed
FREE with bearer — the flattened lead-graph columns available for an enriched batch, i.e. the columns its stock CSV download would have, each with a sample value and how many sampled rows carry one. Store a returned source_ref on a profile column to copy that value instead of asking the model for it: that is excluded from mapping_hash, so adding one never re-bills an already-mapped file. A lead graph is sparse, so a path missing here may exist on a row outside the sample. Recipe: /cookbook/custom_export_builder.

FREE with bearer — quote an export mapping run: per_lead_usd, rows_billable, total_usd, mapping_hash, and shortfall_usd + topup_url when the balance is short. rows_cached rows cost $0.00; is_rebuild=true means the whole run is free. Quote with the same file_instructions you will submit — they feed the mapping_hash. Always call this before export_run_submit.

Precharges at submit and refunds the unused remainder on settle or cancel. Rows already mapped under the same mapping_hash cost $0.00, so a re-export of the same leads with the same mapping semantics is free (scope_kind=rebuild).

export_run_preview unknown never probed
PAID per cache-miss row at the same per-row price as a run — debited from virtual USD balance first, wallet x402 only once that balance is exhausted. Maps 1–5 rows and returns each cell beside the deterministic hint ranking (hint_rank null = the ranker never offered that value). Cache hits are free; misses are banked to the map cache so the later full run does not re-charge them, and degraded rows are refunded. Use to sanity-check instructions before paying for the whole file. ASYNC: rows map in parallel but one row can take over a minute, so this returns a preview_id — poll export_preview_get until status is completed. Only a fully cached preview returns the result inline.

FREE with bearer — upsert up to 500 durable cell overrides (201). No LLM call and no re-run needed. CSV assembly precedence is a contract: row override, then file override, then the mapper's output_json, then empty. output_json is never mutated, so revoking restores the mapped value. literal values are human-typed and bypass the no-invention validator, so downloads count them in the X-411data-Human-Literal-Cells header.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
