# Nomic Embed > Nomic's hosted embedding endpoints on the Atlas API turn text and images into vectors with the open-weight Nomic Embed models. Agents call them over HTTP with an API key or through the Python and TypeScript clients. - Canonical: https://www.anchorterminal.com/tools/nomic-embed - Markdown: https://www.anchorterminal.com/tools/nomic-embed.md (~6,700 tokens) - Slim: https://www.anchorterminal.com/tools/nomic-embed.min.md (~1,530 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/nomic-embed.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (full text: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - Updated: 2026-10-08 ## Overview **Grade D · 49.2/100 · rank #613 of 722 · #7 in Embeddings & rerankers · not agent-ready · confidence medium** More from Nomic, Inc., listed separately because each is its own product: [GPT4All](https://www.anchorterminal.com/tools/gpt4all.md) (Local AI). ## Assessment The text models have Apache-2.0 weights and a public OpenAPI 3.1 contract, so vectors made through the hosted endpoint can be reproduced locally. Nomic's current site and documentation index describe a construction-industry product, no rendered public page prices the endpoint, and no published terms or status component name it. ## Facts | Field | Value | | --- | --- | | Vendor | Nomic, Inc.

Sign-up is in a browser, and we couldn't confirm that new accounts are still accepted (https://docs.nomic.ai/api/getting-started/getting-started). | | Pricing | Freemium (Freemium) · No rendered public page prices the embedding endpoint. www.nomic.ai/pricing lists only the Nomic Platform plans (Free, Individual at $20 a month, Business at $40 a user a month). The Atlas web app's script lists a starter plan with 10M tokens free and paid plans at $1 per 10M tokens with 10M or 100M included a month, and images at $1 per 50,000.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 38 | 7.6 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 65 | 10.6 | | Agent ergonomics | 13% | 16.2 | 69 | 11.2 | | Security & auth | 14% | 17.5 | 62 | 10.8 | | Payments & pricing | 10% | 12.5 | 20 | 2.5 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 28 | 2.5 | | Transparency & trust (editorial 47, provenance 45) | 7% | 8.8 | 46 | 4.0 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **49.2 → D** | ### Why each score - Reliability 38: Graded as a hosted service, on the embedding endpoints at api-atlas.nomic.ai. status.nomic.ai exists but its components are the Nomic Platform in four regions, with none for api-atlas.nomic.ai (5 of 20). Its history from July to October 2026 lists six incidents on the platform, none naming embeddings, so there is no readable record for this endpoint (5 of 30). The limit is published as 1,200 requests per five-minute rolling window per IP address (15). Retry-After on a 429 is documented for the Platform v0 API only. For embeddings the evidence is the Python client, which retries 429 and 5xx up to five times with exponential backoff, and the calls only read (8 of 15). No SLA found, and the Individual terms promise reasonable commercial efforts (0). The embedding pages sit in the main API reference and the endpoint answers, but the API is versioned v0.57.0, the legacy reference warns its endpoints are unstable, and the current documentation index omits Atlas (5 of 10). - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 65: OpenAPI 3.1 document for the Atlas API, v0.57.0, public at api-atlas.nomic.ai/v1/api-reference/openapi.json (25). docs.nomic.ai/llms.txt exists but lists no embedding page, and the Markdown copies it describes return 404 for the Atlas and reference pages (3 of 10). The reference and the generate-embeddings guide say which task_type fits queries, documents, classification and clustering (14 of 20). model and long_text_mode are enums and texts is required, but task_type is a free string in the spec and dimensionality has no bounds (10 of 15). curl, Python and requests examples, with only a 422 validation error documented. We saw an undocumented 403 with the body Unauthorized user (7 of 15). The spec carries a version and /v1/version answers, but there's no API changelog and the docs page and the spec disagree on the model list (6 of 15). - Agent ergonomics 69: dimensionality from 64 to 768 on nomic-embed-text-v1.5, floats only, with no binary or base64 output (18 of 25). Batched texts, long_text_mode and max_tokens_per_text control input size, though the Python client caps a request at 10 texts since 3.5.3 (14 of 20). One documented error, a 422 with field locations, and a bare 403 for a missing key (8 of 20). Stateless read-only calls that are safe to repeat, with backoff built into the Python client and no idempotency key needed (16 of 20). Only texts is required, and there are official Python and TypeScript clients, both without a release in 2026 (13 of 15). - Security & auth 62: Bearer API keys created and deleted in the Atlas dashboard or through key endpoints, scoped to an organisation, a dataset or a user. No rotation or expiry documented (25 of 30). The embedding calls only compute vectors, and Atlas roles from Owner to Guest limit who can create keys, but a key scoped to an organisation also reaches dataset endpoints (12 of 20). The endpoint returns vectors and token counts, no untrusted content (10 of 15). The API has organisation usage endpoints. No per-call log for Atlas was found, and the audit log Nomic documents belongs to the Platform v0 API (5 of 15). The security page gives security@nomic.ai with acknowledgement in five business days, and says Nomic is SOC 2 Type II certified with annual penetration tests, the report under NDA. That page is written for Business and Enterprise platform accounts. No security.txt and no bug bounty found (10 of 20). - Payments & pricing 20: No x402, MPP or L402 (0). www.nomic.ai/pricing lists only the Nomic Platform plans. The Atlas web app's script lists $1 per 10M tokens and $1 per 50,000 images, but atlas.nomic.ai/pricing renders only in a browser and we couldn't read it as a page (10 of 20). The same script lists a starter plan with 10M tokens free. Whether a card is needed, and whether new accounts are accepted, wasn't confirmed (10 of 20). Sign-up is in a browser, and the key-creation endpoint needs an existing login (0). - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 28: The Atlas API reports v0.57.0 with no date. /v1/version dates its newest component, convert, 19 June 2026, 111 days ago, and the embedding model cards for v1 and v1.5 were last changed on 7 April 2026 (10 of 30). No dated API changes or client releases in the last 90 days (0 of 20). The Python client's repository has 50 open issues, with the newest issue activity on 19 March 2026, and a community Slack is linked from the docs (5 of 25). Official clients exist for Python (nomic 3.9.0, 11 November 2025) and TypeScript (@nomic-ai/atlas 0.12.0, last pre-release 16 September 2025), neither released in 2026 (8 of 15). The Python repository has a CircleCI configuration, a changelog and typed packaging, with its last commit on 11 November 2025 (5 of 10). - Transparency & trust 46: The hosted API is closed, while the weights for the text, code and vision models are Apache-2.0 on Hugging Face and the Python client declares Apache, though its repository has no licence file (25 of 30). No published terms or privacy policy name Atlas or the embedding API. The privacy policy covers www.nomic.ai and app.nomic.ai, the Business and Enterprise terms forbid training on Customer Data, and the Individual terms allow use to improve the technology behind it, so the position for embedding inputs is unclear (8 of 30). The Individual terms promise 30 days' notice before endpoints change and six months of support for the previous API version, where an order includes the API. No dated notices for Atlas found (8 of 20). The security page lists hosting regions and subprocessors for the platform, and the privacy policy says servers are in the US. Nothing specific to api-atlas.nomic.ai (6 of 20). Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (20 items): https://www.anchorterminal.com/fixes/nomic-embed.md (JSON https://www.anchorterminal.com/fixes/nomic-embed.json) ### What we couldn't check - unchecked: whether atlas.nomic.ai still accepts new sign-ups and issues API keys to them. The app renders only in a browser. Its script contains Log In and Sign Up buttons - unchecked: the rendered Atlas pricing page. The app's script lists a starter plan with 10M tokens free and $1 per 10M tokens on paid plans, which is where the listed price comes from. Whether a card is needed wasn't established - Which terms and privacy policy govern the Atlas embedding API. None of Nomic's three published legal documents names it - Whether Nomic trains on text sent to the embedding endpoint. The Business and Enterprise terms forbid training on Customer Data, while the Individual terms allow use to improve the technology behind it - The docs page lists nomic-embed-text-v1 and v1.5 as the model values, while the OpenAPI document also lists nomic-embed-text-v2, nomic-embed-code, gte-multilingual-base and all-MiniLM-L6-v2. Which of these the endpoint serves wasn't tested, since we had no key - unchecked: the 429 response of the embedding endpoint. Retry-After is documented for the Platform v0 API only - Whether Nomic plans to retire the Atlas API. No dated notice was found, but the legacy reference warns its endpoints may be removed and the current documentation index omits Atlas - The lead said the API page names only v1 and v1.5, which is right for the docs page. The OpenAPI document names six text models and two vision models ### Sources - Embed Text API reference: (seen 2026-10-08) - Atlas API OpenAPI 3.1 document, v0.57.0: (seen 2026-10-08) - API version endpoint: (seen 2026-10-08) - rate limits, including the Embedding Inference API: (seen 2026-10-08) - text embedding models, context length and dimensions: (seen 2026-10-08) - generate embeddings guide, task types and local inference: (seen 2026-10-08) - authentication: (seen 2026-10-08) - Atlas roles and API key scoping: (seen 2026-10-08) - legacy API warning: (seen 2026-10-08) - documentation index for agents: (seen 2026-10-08) - public pricing page, platform plans only: (seen 2026-10-08) - Atlas web app, whose script holds the plan prices: (seen 2026-10-08) - legal document index: (seen 2026-10-08) - Individual Terms of Service, 25 August 2026: (seen 2026-10-08) - Terms of Service for Business and Enterprise, 20 April 2026: (seen 2026-10-08) - privacy policy, 15 January 2026: (seen 2026-10-08) - security page: (seen 2026-10-08) - status page and history, July to October 2026: (seen 2026-10-08) - Python client repository, changelog and embed module: (seen 2026-10-08) - Python package: (seen 2026-10-08) - TypeScript package: (seen 2026-10-08) - nomic-embed-text-v1.5 model card and licence: (seen 2026-10-08) ## Who's behind it (provenance 45/100, checked 2026-10-08) | Check | Finding | Points | | --- | --- | --- | | Legal entity named | Nomic, Inc. | 20/20 | | Domain age | nomic.ai, no registry record we could read | 0/15 | | Endpoint on the vendor's domain | api-atlas.nomic.ai | 15/15 | | Terms of service | not found | 0/10 | | Privacy policy | not found | 0/10 | | Status page | not found | 0/10 | | Changelog | published | 10/10 | | security.txt | not found | 0/10 | terms and privacy are left out. Nomic publishes Terms of Service for Business and Enterprise accounts (20 April 2026), Individual Terms of Service for Free and Individual accounts (25 August 2026) and a privacy policy (15 January 2026) that covers www.nomic.ai and the platform at app.nomic.ai. None names Atlas, atlas.nomic.ai or the embedding API (https://www.nomic.ai/legal.json). Both sets of terms name Nomic, Inc., a Delaware corporation, under Delaware law. status.nomic.ai lists the Nomic Platform in four regions (drive.nomic.ai, au, eu and uk), each with a Nomic API and a Platform Web Service component. It has no component for api-atlas.nomic.ai, so statusPage is left empty. www.nomic.ai, docs.nomic.ai and api-atlas.nomic.ai each return 404 for /.well-known/security.txt. The security page gives security@nomic.ai for vulnerability reports. The changelog is the Python client's. No changelog for the Atlas API was found. ### Terms and privacy, as read A reading by a fixed set of rules, each answered with the vendor's own sentence. Not legal advice. **Terms of service**. We found no terms of service published for this product, so there is nothing to read and the check scores 0. **Privacy policy**. We found no privacy policy published for this product, so there is nothing to read and the check scores 0. ## Live (updated 2026-10-08 20:21 UTC) - Right now: up, HTTP 405, 417 ms, checked 2026-10-08 20:21 UTC (get on `https://api-atlas.nomic.ai/v1/embedding/text`) - Uptime 24h 100.0% (32 probes) · 30 days 100.0% (32 probes) · p50 425 ms · p95 467 ms - Watching changelog - Always current: https://www.anchorterminal.com/api/v1/live/nomic-embed.json ## Probe metrics Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | Text embedding tokens beyond the plan's monthly allowance | $0.10 | per 1M tokens | $1 per 10M tokens, read from the Atlas web app's script, not a rendered pricing page | Across all listings: https://www.anchorterminal.com/prices/index.md ## Strengths - Weights for nomic-embed-text-v1, v1.5, v2-moe, nomic-embed-code and nomic-embed-vision-v1.5 are Apache-2.0 on Hugging Face - Public OpenAPI 3.1 document for the Atlas API (v0.57.0) with typed request and response schemas for both embedding endpoints - nomic-embed-text-v1.5 accepts a dimensionality from 64 to 768, and inputs up to 8,192 tokens per text - The Python client retries 429 and 5xx responses with exponential backoff and can run the same model locally with inference_mode set to local - API keys can be scoped to an organisation, a dataset or a user, per the Atlas access-control page ## Weaknesses - docs.nomic.ai/llms.txt and www.nomic.ai now describe a product for architecture, engineering and construction firms, and the documentation index no longer lists the embedding pages - No rendered public page states a price for the endpoint. The $1 per 10M tokens figure comes from the Atlas web app's script - status.nomic.ai has no component for api-atlas.nomic.ai, and no SLA was found - The published terms and privacy policy cover the Nomic Platform at app.nomic.ai and don't name Atlas or the embedding API - The Python client's last release was 3.9.0 on 11 November 2025, and the API reference documents only a 422 error ## Before you call it (notes for agents) 1. Set task_type to search_query for queries and search_document for stored text. The default is search_document 2. Name the model in every request. The API defaults to nomic-embed-text-v1, while the Python client defaults to nomic-embed-text-v1.5 3. Keep under 1,200 requests per five minutes per IP address. The Python client sends at most 10 texts a request 4. Set long_text_mode to truncate or mean. Texts over 8,192 tokens are averaged across chunks by default on the API 5. Pass dimensionality only with nomic-embed-text-v1.5, between 64 and 768 ## Connect Install: ```bash pip install nomic ``` First request: ```bash curl -X POST https://api-atlas.nomic.ai/v1/embedding/text \ -H "Authorization: Bearer $NOMIC_API_KEY" -H "Content-Type: application/json" \ -d '{"texts":["The text you want to embed."],"model":"nomic-embed-text-v1.5","task_type":"search_document"}' ``` Through letme (picks today, calling later): https://letme.dev/nomic-embed. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.
