How to use the Adaptyv Bio Foundry API and Python SDK for protein experiment design, submission, and results retrieval. Use this skill whenever the user mentions Adaptyv, Foundry API, protein binding assays, protein screening experiments, BLI/SPR assays, thermostability assays, or wants to submit pr

Adaptyv Bio Foundry API Use this skill to turn protein sequences into experimentally measured data through Adaptyv's cloud laboratory. Confirm the target construct, assay conditions, controls, and replicate plan before submitting a batch; turnaround depends on the experiment. Reviewed against the deployed [OpenAPI schema](https://devs.adaptyvbio.com/api/v1/openapi.json) ( info.version: 0.0.2 ) and official SDK 0.1.0 at commit cdf207819ed5a58e0c127453626d2bce125c8064 . The schema version alone does not identify all changes. See the [endpoint reference](references/api endpoints.md) for current request/response details and discrepancies in upstream examples. Connect Base URL: https://devs.adaptyvbio.com/api/v1 . The schema is at /openapi.json ; never append that filename to normal endpoint requests. Create a bearer token in [Foundry](https://foundry.adaptyvbio.com/) under Organization → Settings → Tokens. Use Viewer for reads and Member for experiment writes. Read credentials from ADAPTYV API KEY ; the documentation's FOUNDRY API TOKEN is an alternative variable name for the same token. If using a project .env , explicitly call python dotenv.load dotenv() before SDK setup; the SDK does not load that file automatically. Never print or commit tokens. Resource endpoints require bearer authentication. The schema and liveness endpoint GET /info/health are public. GET /whoami reports the active organization and permissions; check it when account scope is unclear. Python SDK Install the reviewed revision in your project environment (requires Python 3.11+): Import from adaptyv , not adaptyv sdk . FoundryClient requires explicit api key and base url ; the lab convenience object reads ADAPTYV API KEY and ADAPTYV API URL . Set the latter to the base URL above to override the SDK's older hostname default. The following examples are illustrative for authenticated use. Their request construction and parsing were checked with mocked HTTP responses, not a paid lab run. Replace environment inputs with real, reviewed sequence data and catalog IDs. Browse, estimate, create a draft create(name=..., experiment spec=...) does not accept a single REST body dictionary. cost estimate(spec) wraps the spec itself; do not wrap it a second time. For an affinity experiment, the SDK additionally requires explicit antigen concentrations , even though REST supplies a default when omitted. Submit, then inspect and confirm the quote With a configured client and the saved experiment id : Confirmation creates/finalizes an invoice; it does not settle payment. Use the returned hosted invoice URL or the current REST payment pointer. SDK 0.1.0 does not expose invoice payment, organization webhooks, or whoami helpers. Avoid the reviewed SDK's lab.experiment(target="EGFR") shortcut: it passes only UUID shaped targets and does not resolve a target name. auto confirm=True and lab.confirm experiment() call submission, not the quote confirm endpoint. Use the explicit client methods above. The decorator also supplies method for non binding experiments, which the current API rejects. Retrieve every result without losing fields The SDK's generated models predate some live result fields and may discard them. Use REST JSON when archiving results, target references, or newer kinetic fits: Archive raw data packages when available, plus sequence/target identities, assay method, units, conditions, replicate measurements and fit quality. Null kinetic values are missing/unresolved measurements, not zero. A screening binding call is not a measured affinity. Compare KD values only under compatible assay conditions; the schema's kd mean averages strong binding replicates and is not an unbiased summary of every tested replicate. Experiment types and validation experiment type method target id Sequence count Replicates affinity Required: bli or spr Required At least 1 Optional, 1–5; default 3 screening Required: bli or spr Required At least 1 Optional, 1–5; default 3 thermostability Omit Omit At least 1 Optional, 1–5; default 3 expression Omit Omit At least 1 Optional, 1–5; default 3 fluorescence Omit Omit At least 1 Optional, 1–5; default 3 epitope binning Omit Required 4–28, multiple of 4 Omit enzyme activity Omit Omit At least 1 Optional, 1–5; default 3 Inapplicable fields are rejected. antigen concentrations is affinity only, in nM; REST's default is [1000.0, 316.2, 100.0, 31.6, 0.0] . parameters holds optional assay settings; coordinate any nonstandard configuration with the laboratory. Sequences accept full strings or rich entries such as {"candidate": {"aa string": "EVQLVESGGGLVQPGGSLRLSCAAS", "control": false}} . Use the 20 standard amino acid letters; inputs are case insensitive and stored uppercase. Colons separate chains. Ellipses are not valid sequence characters. Rich creation metadata is constrained by SequenceMetadata , not arbitrary JSON: use SingleChain , ScFv , FAB , or IgG ; ScFv needs VH and VL , FAB needs framework regions.ch and .cl . The SDK accepts the schema's Portal style enum values. Add sequences through POST /sequences only while status is draft . Lifecycle and updates Wire status values are lowercase snake case: canceled is also possible. results status is independently none , partial , or all . Inspect it before treating a result set as complete. Most experiment PATCH fields are editable in draft or in review ; webhook url remains editable at any status. A sequence PATCH replaces the sequence list; POST /sequences appends to a draft. Create time REST flags skip draft and auto accept quote enable automation; auto accept quote implies skip draft and requires full pricing. They can commit the batch to laboratory processing and billing, so use them only within the user's approved experiment/budget scope. The SDK's public create() method does not expose auto accept quote , webhook secret , or the payment selector; use the REST contract in the reference when these fields are needed. For signed delivery, set a per experiment webhook url and webhook secret (minimum 32 characters) at creation, or register an organization webhook. Store the secret when setting it; it is write only. An experiment webhook overrides organization delivery. Verify X Adaptyv Signature ( sha256=<hex ) as HMAC SHA256 over the raw body with constant time comparison. Events are experiment update customer facing updates, not a complete stream of status transitions. Deduplicate by data.update id ; delivery id identifies an attempt. Return 2xx ; network failures and 5xx retry up to three times, while 4xx is permanent. Continue to poll status/results if delivery is missing. Lists, filters and errors Paginated endpoints return {items, total, count, offset} ; use limit 1–100 (default 50) and offset (default 0). Fetch all pages. Query support varies by endpoint: sequence lists lack filter , token lists only paginate, and organization webhooks return an unpaginated array. See the endpoint reference. Where supported, filters use eq(field,value) , neq , gt , gte , lt , lte , contains , between , in , is null , is not null , combined with and , or , not . Example: and(gte(created at,2026 01 01),eq(status,done)) . Sorting accepts asc(field) / desc(field) (up to eight comma separated terms), field / +field , or field:asc / field:desc . Use the HTTP client's query encoder. Advanced expressions support at(field,key) and casts ( float , int , text , timestamp , date ), subject to each endpoint's allowed fields. Structured errors generally include error and request id ; record the x request id header for support. Handle non JSON transport failures too. Check status before retrying mutations after an ambiguous timeout: the server may already have created the experiment or accepted a quote. The SDK retries 429/5xx responses; its retries do not establish mutation idempotency. Token attenuation only narrows permissions. POST /tokens/revoke revokes the calling token's root family , including siblings descended from that root, even when authenticating with an attenuated token.
