"## Overview\n\n**Grade D · 48.6/100 · rank #867 of 1076 · #11 in Health records \u0026 wellness data · not agent-ready · confidence medium**\n\n\n## Assessment\n\nParticle queries Carequality, CommonWell, eHealth Exchange and state HIEs for a patient and returns FHIR R4B, flat data or C-CDA, with project-scoped 60-minute tokens and OpenAPI fragments per endpoint. Credentials come through a representative, the free sign-up link was dead on 14 October 2026, and rate limits, SLA and changelog are unpublished.\n\n## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | Particle Health, Inc. (https://particlehealth.com) |\n| Kind | HTTP API |\n| Category | Health records \u0026 wellness data (https://www.anchorterminal.com/categories/health-data) |\n| Transport | HTTP |\n| Auth | OAuth · OAuth 2.0 client credentials. A Particle representative issues the first client ID and secret, after which the Management APIs can create service accounts and credentials, and creating new credentials expires the old ones. Each token request must name one project as its scope, and tokens last 60 minutes. Service accounts carry IAM roles such as `roles/project.owner`. |\n| Pricing | Paid (Paid) · No public prices. The developers page links 'play for free' to portal.particlehealth.com/signup, which did not resolve on 14 October 2026, and the docs ask developers to contact a representative for credentials. The sandbox allows 500 queries per organisation a day (checked 2026-10-14). |\n| x402 | No · No x402, MPP or L402 in the docs, llms.txt or the website (checked 2026-10-14). |\n| Licence | Proprietary service under customer agreements.

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.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 58 | 11.6 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 69 | 11.2 |\n| Agent ergonomics | 13% | 16.2 | 53 | 8.6 |\n| Security \u0026 auth | 14% | 17.5 | 57 | 10.0 |\n| Payments \u0026 pricing | 10% | 12.5 | 5 | 0.6 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 27 | 2.4 |\n| Transparency \u0026 trust (editorial 27, provenance 69) | 7% | 8.8 | 48 | 4.2 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **48.6 → D** |\n\n### Why each score\n\n- Reliability 58: Read with the hosted lines. status.particlehealth.com on Statuspage with 7 components and history (20). In the last 90 days, CommonWell traffic was disrupted for about five and a half hours on 5 August 2026, marked critical, and a Google Cloud zone outage on 1 September raised risk with no impact recorded. We read the first as a network-side outage, as for the other network listings (15 of 30). Rate limits exist per project with no numbers, apart from the sandbox's 500 queries a day (5 of 15). 429 with a backoff recommendation, no Retry-After or idempotency guidance (8 of 15). No SLA found in public (0). The v2 APIs are generally available (10).\n- 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.\n- Schema \u0026 documentation 69: OpenAPI fragments on each reference page, with no single specification file found (18 of 25). llms.txt and Markdown pages (10). A developer guide by path (Workbench, Signal) and global conventions for IDs, auth and pagination (14 of 20). Typed inputs in the fragments (11 of 15). A Postman collection and an error code table with context (11 of 15). Versioned /api/v1 and /api/v2 paths and legacy flows marked, but no changelog, which returns 404 (5 of 15).\n- Agent ergonomics 53: FHIR by resource type or ID, flat data filtered by domain, and Snapshot AI summaries where enabled (17 of 25). Continuation tokens and filters (16 of 20). Standard HTTP codes with some context (12 of 20). No idempotency keys or safe-retry guidance (3 of 20). No official SDK (5 of 15).\n- Security \u0026 auth 57: OAuth 2.0 client credentials with a mandatory project scope, 60-minute tokens, rotation that expires old credentials, and IAM roles on service accounts (27 of 30). Project-scoped tokens, roles beyond owner on request, purpose-of-use rules and a delegation of authority policy, with deletes allowed and no confirmation step (13 of 20). Records and AI summaries from outside organisations, with no prompt-injection guidance (3 of 15). No audit log for operators found (2 of 15). HITRUST and SOC 2 claimed for the API platform, a vulnerability submission form, no bug bounty or security.txt (12 of 20).\n- Payments \u0026 pricing 5: Read with the hosted rubric. No x402, MPP or L402 (0). No published prices (0). A sandbox with synthetic patients exists, but credentials come from a representative and the free sign-up link did not resolve (5 of 20). A person must be provisioned by Particle (0).\n- 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.\n- Maintenance \u0026 community 27: No dated release was found. Docs pages were updated on 13 October 2026, and v2 subscription endpoints sit beside v1, which we read as recent change without a release record (20 of 30). No changelog (0). Support through a representative, with no public record (5 of 15). No official SDK found (0 of 15). A maintained Postman collection (2 of 10).\n- Transparency \u0026 trust 48: Closed service. The public terms date from 2020 and cover only the website, and no developer or API terms were found (10 of 30). The privacy policy (July 2026) covers the site only and keeps de-identified aggregate data, with no retention periods or public DPA (8 of 30). Legacy flows are labelled as supported for existing customers, with no dates (5 of 20). Google Cloud is named as the platform, with no sub-processor list or regions (4 of 20).\n\nFix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (15 items): https://www.anchorterminal.com/fixes/particle-health.md (JSON https://www.anchorterminal.com/fixes/particle-health.json)\n\n### What we couldn't check\n\n- portal.particlehealth.com, the target of the 'play for free' link, had no DNS record on 14 October 2026, so the free route could not be checked\n- Production base URL not confirmed in the pages read, which show the sandbox host\n- No developer terms, SLA or DPA were found in public\n\n### Sources\n\n- documentation index: \u003chttps://docs.particlehealth.com/llms.txt\u003e (seen 2026-10-14)\n- getting started for developers: \u003chttps://docs.particlehealth.com/docs/getting-started-for-developers.md\u003e (seen 2026-10-14)\n- auth and keys: \u003chttps://docs.particlehealth.com/docs/auth-and-keys.md\u003e (seen 2026-10-14)\n- rate limiting: \u003chttps://docs.particlehealth.com/docs/rate-limiting-and-quotas.md\u003e (seen 2026-10-14)\n- sandbox: \u003chttps://docs.particlehealth.com/docs/test-patient-sandbox.md\u003e (seen 2026-10-14)\n- API getting started: \u003chttps://docs.particlehealth.com/reference/getting-started.md\u003e (seen 2026-10-14)\n- handling errors: \u003chttps://docs.particlehealth.com/reference/handling-errors.md\u003e (seen 2026-10-14)\n- developers page: \u003chttps://particlehealth.com/developers\u003e (seen 2026-10-14)\n- status incidents: \u003chttps://status.particlehealth.com/api/v2/incidents.json\u003e (seen 2026-10-14)\n- security: \u003chttps://particlehealth.com/security\u003e (seen 2026-10-14)\n- terms of use: \u003chttps://particlehealth.com/terms-of-use\u003e (seen 2026-10-14)\n- privacy policy: \u003chttps://particlehealth.com/privacy-policy\u003e (seen 2026-10-14)\n\n## Who's behind it (provenance 69/100, checked 2026-10-14)\n\n| Check | Finding | Points |\n| --- | --- | --- |\n| Legal entity named | Particle Health, Inc. | 20/20 |\n| Domain age | particlehealth.com, registered 2017-11-22 (8 years) | 11/15 |\n| Endpoint on the vendor's domain | particlehealth.com | 15/15 |\n| Terms of service | read, states 6 of the 7 things a reader expects, and has 2 clauses that cost points | 5.1/10 |\n| Privacy policy | read, states 5 of the 8 things a reader expects | 7.8/10 |\n| Status page | status.particlehealth.com | 10/10 |\n| Changelog | not found | 0/10 |\n| security.txt | not found | 0/10 |\n\nThe terms of use (effective 15 October 2020) cover the website, forbid users to 'harvest or scrape any content or data from the Site', and may change without notice.

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.\n\n## Strengths\n\n- Connected to all three national networks plus Healthix, Manifest MedEx and Surescripts\n- Tokens scoped to one project and expiring after 60 minutes, with credential rotation that retires old secrets\n- FHIR R4B, flat datasets and C-CDA from the same query\n- Sandbox of synthetic patients across every production workflow, 500 queries a day\n\n## Weaknesses\n\n- Credentials come from a Particle representative, and the 'play for free' sign-up domain did not resolve\n- Rate limits vary with load and have no published numbers\n- No changelog, SLA or developer terms in public\n- No audit log for operators was found\n\n## Before you call it (notes for agents)\n\n1. Pass `projects/\u003cproject_id\u003e` as the scope when requesting a token, and request a new one every 60 minutes\n2. Poll Get Query Status, or wait for the query-complete webhook, before reading FHIR or flat data\n3. Back off on 429, since limits change with system load\n4. Pass continuation tokens back verbatim when paging\n5. Use the published synthetic patients in sandbox, and stay under 500 queries a day\n\n## Connect\n\nFirst request:\n\n```bash\nPOST https://sandbox.particlehealth.com/api/v2/patients\nAuthorization: Bearer \u003caccess-token\u003e\nContent-Type: application/json\n```\n\nThrough letme (picks today, calling later): https://letme.dev/particle-health. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.
